Real-Time Monitoring Solutions for -80°C ULT Freezers and Cryopreservation
Maintaining the integrity of biological samples stored in ultra-low temperature (ULT) freezers and cryogenic units is paramount. Telemetry2U offers advanced real-time monitoring solutions utilizing LoRaWAN technology, providing instant alerts and comprehensive data tracking to safeguard your valuable assets.
Reliable LoRaWAN Monitoring for Ultra-Low Temperature Freezers
Monitoring Ultra-Low Temperature (ULT) freezers and cryo storage systems (liquid nitrogen storage at approximately -180°C) is essential for preserving sensitive biological samples. Even slight temperature variations can lead to compromised integrity and significant scientific and financial loss.

LoRaWAN Hardware That’s Simple, Reliable, and Cost-Effective
We use LoRaWAN (Long Range Wide Area Network), a low-power, long-range wireless communication protocol designed specifically for IoT applications. In a laboratory setting, LoRaWAN provides reliable, real-time data transmission across long distances, even in complex indoor environments. Its low energy consumption means sensors can operate for years without battery replacement. The robust signal and scalable architecture make it ideal for monitoring multiple ULT freezers and cryogenic storage units.
1. LoRaWAN Gateway
A LoRaWAN gateway communicates with sensors using long-range RF and sends data securely to the cloud via Ethernet, Wi-Fi, or 4G. It supports hundreds of sensors with strong noise immunity and range. Telemetry2U provides easy-to-follow network setup guides to help with integration—even if IT support is needed. A 4G backup with battery ensures reliable cloud connectivity.
2. Dragino LTC2-LT LoRaWAN Temperature Sensor
The Dragino LTC2-LT temperature sensor is ideal for long-term ULT monitoring. Its 10+ year battery life and LoRaWAN compatibility allow efficient data transmission. It’s easy to install via a freezer’s insulated port or cryo store thermowell, and the optional magnetic mount simplifies positioning. Fully integrated with Telemetry2U, it ensures reliable, accurate readings even at extreme temperatures.
3. NATA Calibration Certificate
Accurate sensor readings are essential in healthcare and laboratory environments. NATA (National Association of Testing Authorities) calibration confirms sensor accuracy using controlled environments. If needed, adjustments are made before certification is issued. Certificates are stored in the cloud and can be accessed anytime. In many cases, future recalibrations can be performed onsite to suit your operational needs.
Optional Monitoring via 4–20 mA Signal Integration
Some -80°C freezers, including Thermo Fisher’s TSX, TSU, and RDE models, offer a 4–20 mA analogue output scaled from -105°C to 50°C via the alarm port at the rear of the unit.
At Telemetry2U, we support seamless integration of this output using LoRaWAN or NB-IoT nodes, such as the Dragino PS-LB-NA (LoRaWAN) and the PS-NB-NA (NB-IoT). This provides an alternative method for monitoring ultra-low temperature freezers with accurate, real-time data that matches the freezer’s display.
The integration is non-invasive and simple to install—no need to power down or defrost the unit.
Remote Door Monitoring with Reed Switch
These nodes also include a digital input for reed switch monitoring. This allows you to track door open/close events and duration, helping staff decide whether overnight alerts need urgent action.
