MaxLinc makes smart environmental data loggers that track temperature, humidity, CO2, air quality, pressure, current and more — and instantly call, text or email you if a reading drifts out of range. Every EDGE and BLOCK logger is designed and built in Vancouver, BC and includes a free cloud dashboard.

EDGE is the everyday line for temperature, humidity and air quality — with an on-device screen, buzzer and visible alarm — in matched WiFi and Cellular versions. BLOCK is the industrial/retrofit line with plug-in sensors for pressure, current, pulse counting and 4-20 mA loops, where the calibration lives with the swappable sensor.

WiFi connects to your existing 2.4 GHz network and keeps a free cloud tier forever. Cellular has a built-in eSIM and works with no WiFi (first year included, then $3/month or $36/year). NFC loggers are single-use, disposable tags for cold-chain shipments that you read with a phone tap.

Essential (room temperature + humidity), Essential PLUS (enhanced accuracy), Thermo (two external temperature probes down to -55 °C / -67 °F, for fridges and freezers), Pharma One and Pharma Two (one or two buffered, NIST-traceable probes with calibration certificate, for vaccine and pharmacy fridges), and Air (CO2, VOC and air quality).

Each industry page on maxlinc.com (food service, pharmacy, HVAC, cold chain, museums, healthcare, property management, industrial) recommends a configuration, and the shop's picker helps you choose. Or email Support@MaxLinc.com and we'll spec it for you.

No — on WiFi, devices keep working free forever on the Standard tier: live data, all alarms, 45 days of history and Excel export (email and push alerts are free; texts and calls use the $5 alert credit included with every device). Every device includes its first year of Premium; after that, Premium is optional on WiFi at $2/month for advanced reports and full history. Cellular devices include everything for the first year, then $3/month or $36/year per device, with no contract.

Cellular units include a built-in eSIM that pays for its own mobile data, so the roughly $3/month after year one covers the network. WiFi units use your own internet, so there's nothing to pay. Many competing systems charge around $25/month per device, forever.

On WiFi, nothing critical — the device keeps recording and sending alarms, and you keep live data, the most recent 45 days of history and Excel export. Premium adds advanced reports (Create Report and Automatic Report), full history and sharing a device with new users. Cellular devices need their $3/month plan after the first year to stay connected.

No. It's a progressive web app that runs in any browser on a phone, tablet or computer — nothing to download from an app store. On a phone you can optionally add it to your home screen so it behaves like an app.

On Canadian cloud servers, with daily backups and redundancy — a deliberate data-residency and privacy choice. The dashboard interface is available in more than 20 languages.

Yes. Devices are shared by role: Owner (full control), Editor (settings and thresholds), Viewer (read-only), Silent Viewer (read-only, no alarms) and Service & Maintenance (for technicians). You can share with unlimited people and add unlimited alarm recipients.

Yes. On the free Standard tier you can export raw readings to Excel. With Premium (included for each device's first year), any report exports to PDF, Excel or CSV and can be scheduled to email automatically. For integrations, data APIs and real-time alarm webhooks can push readings into an ERP, BMS or SCADA system.

Tool-free and quick. For WiFi you connect the device to your network in the app and you're monitoring in minutes — no installer needed. Cellular units connect themselves over the built-in eSIM.

The device joins any standard 2.4 GHz network (it does not use 5 GHz). During setup you briefly connect your phone to the device's temporary hotspot, a setup page opens, and you pick your network and enter the password. A short beep pattern confirms success.

No SIM to insert and no carrier contract. The eSIM is built in and works across 170+ countries with no roaming charges. Year one of connectivity is included; after that it's covered by the roughly $3/month plan.

Yes. Cellular units can also connect to WiFi and roll over between the two automatically, so you keep coverage if one path drops.

Alarms are effectively real-time — a threshold breach uploads and alerts you immediately. Routine readings upload on a sync interval you choose (1 minute to 24 hours), set separately from how often the device records, so more frequent syncing gives finer data at the cost of battery.

No. The logger keeps recording to internal memory while offline (tens of thousands of readings) and uploads everything it missed as soon as it reconnects, so your history has no gaps.

About 2 years on 4 standard AA batteries for EDGE WiFi models, about 1 year for EDGE Cellular and about 2.5 years for BLOCK WiFi. Real-world life depends on how often it syncs, how much alarm activity there is, signal strength and temperature.

Yes — EDGE and BLOCK units accept USB-C power and switch to it automatically when plugged in, falling back to batteries if external power is lost. That's ideal for permanent installations.

Yes. The device shows a low-battery indicator and the cloud sends a low-battery email alert. Always replace all the batteries at the same time with fresh, good-quality AA cells.

By SMS text, automated phone call, email and mobile push notification, plus an audible buzzer and visible alarm on the device itself. Alerts repeat until the reading is back within your limits; anyone can acknowledge an alarm with a note, and the log keeps their name, the time and the comment.

Yes — you can add an unlimited number of alarm recipients. Each person is added by sharing the device with them, and each controls their own text, call and push preferences.

No — the system has a four-level alarm engine: instant (threshold cross), persistent/delayed (only if the condition holds), trend/drift (warns before a limit is breached), and event-based (flood or door contact). Cumulative time-weighted alarms are also available, such as an 8-hour average CO2 exposure.

Email and push alerts are always free and unlimited. Texts and automated phone calls draw from a prepaid credit on the device: every device ships with $5 of credit (about 250 texts); each text costs $0.02 and each call $0.05. You can top it up from My Profile. If credit runs out, texts and calls pause but email and push keep working. You verify your phone number once first.

Yes. A no-connection alarm notifies you if a device hasn't reported within an expected window, and low-battery and power-change alerts are also available.

Yes. When someone acknowledges an alarm, the who, when and why is written to a tamper-proof, read-only record that can't be edited or deleted — built to support FDA 21 CFR Part 11 and insurance requirements.

Every product page lists that model's temperature, humidity and CO2 accuracy. EDGE Pharma probes are NIST-traceable and come with a calibration certificate, valid up to 5 years on the shelf and 3 years in use.

The certificate is issued to the sensor/probe, not the whole device, and ships with the probe. You can look one up without logging in — enter the probe's ID or scan its QR code to see the issue date, valid/expired status and download the certificate PDF.

No. Because calibration lives with the sensor, you just buy a newly calibrated probe and plug it in — no downtime and no shipping the whole unit away. The cloud emails you before a certificate expires.

Up to five years from its issue date while the probe is still on the shelf, and three years once the probe is put into service. The exact expiry date is printed on the certificate and tracked automatically in the cloud.

MaxLinc is built to support record keeping for HACCP, FDA 21 CFR Part 11, VFC/CDC vaccine storage and GxP/GMP/GDP workflows, with immutable audit logs and NIST-traceable certificates tied to each EDGE Pharma probe. Your own procedures and validation determine compliance.

With Premium (included for each device's first year): HACCP and food-safety logbooks, vaccine temperature reports, Mean Kinetic Temperature (MKT), Vapor Pressure Deficit (VPD), transport and cold-chain logs with GPS, temperature-mapping studies, and min/max/average summaries — all exportable to PDF, Excel or CSV and schedulable by email. The free Standard tier on WiFi keeps a raw Excel export of the last 45 days.

Through PayPal, which securely handles Apple Pay, Google Pay and Visa / Mastercard / American Express. You don't need a PayPal account to pay by card, and we never store your card details.

All orders are charged in Canadian dollars (CAD). US and international visitors can toggle the header to see approximate USD prices, but checkout always bills in CAD and shows a 'billed in CAD' note. Canadian visitors see CAD only.

No — checkout is guest-friendly. Canadian sales tax (GST/HST/PST) is calculated once you select your province.

Yes — signing up through the welcome offer gives 10% off your first order (a minimum order applies). The welcome code can't be combined with other promotions or stacked on already-discounted sale items.

To Canada and the United States. Flat shipping is $15 CAD, and it's free on orders over $100 CAD within Canada (free over US$100 for US customers). For orders outside these regions, contact Support@MaxLinc.com.

Orders are processed and shipped within 1-3 business days, and standard delivery within North America generally takes 3-5 business days (not guaranteed).

We accept returns and exchanges up to 30 days after delivery, for both defective and non-defective items in new, unused condition with original packaging. Return shipping is free and there are no restocking fees; refunds go to your original payment method within about 7 days. Email Support@MaxLinc.com to start one.

Every MaxLinc EDGE and BLOCK logger carries a 24-month limited warranty, counted from the date the device is claimed (registered) to your MaxLinc account. It covers defects in materials or workmanship under normal use and maintenance. If a product or part is found to be defective during the warranty period, we repair or replace it at no charge.

The warranty does not cover consumable parts, such as batteries or hanger stickers; cosmetic damage, including scratches or cracked or broken enclosures; damage caused by accidents, abuse, misuse, liquid contact, fire, earthquakes or other external causes; or defects caused by tampering or repairs performed by unauthorized persons.

Whichever is longer: the remaining warranty of the original product, or 180 days from the date of replacement or repair. For example, a logger replaced in month 23 of its warranty is still covered for 180 days after the replacement, not just the one month that was left.

Hardware loggers ship from Canada, so US customers generally avoid the duty and monthly-fee surprises common with imported alternatives. The one exception is the disposable NFC tag pack, where US import duties and customs fees are the customer's responsibility (noted at checkout).

They're disposable, single-use temperature loggers you drop into a parcel or shipment. On arrival, anyone can tap the tag using an iPhone or Android phone with the free NFC app to read the full temperature history and keep it with your shipping records — no gateway, and no account needed by the person scanning.

The free LoggerFlex NFC Tag Reader app (on the App Store and Google Play). Activate a tag by pressing the button three times within two seconds; it records temperature every 10 minutes, holds about 4,000 readings (roughly four weeks) and runs 2-3 months. No login is needed to scan — a registered email routes the data to your MaxLinc cloud account.

Yes for our EDGE and BLOCK loggers and the Modbus Bridge: designed and built in Vancouver, BC, with data hosted on Canadian servers. The NFC tags, accessories and water meters are made by manufacturing partners, and sold and supported by MaxLinc from Vancouver. The battery-life power management is patented (US Patent US11455877B2).
