 Wireless Ultra Low Temperature Sensor LoRa SPY T3

The long-range wireless data logger LoRa® SPY T3 measures and records ultra-low temperature thanks to an external probe

Designed to monitor low temperature in ultra-low freezers and LN2 tanks, the LoRa® SPY T3 can be placed on the outside thanks to its magnet allowing to visualize data measurement.

Data are sent to the JRI secure Cloud by LoRaWAN™ network of the telecom operators members of the LoRa Alliance™, or by a Micro Gateway private network data transmission module.

In case of threshold excursions, real-time alerts are sent.

Temperature measurements are managed on the JRI MySirius temperature monitoring web application
