The NB-IoT wireless low temperature data logger is designed for accurate temperature recording in environments with extreme cold or fluctuating temperatures. This logger is ideal for cryogenic applications, pharmaceutical storage, food processing and laboratories, where reliable temperature monitoring is essential.
The logger measures temperatures from -200 to +200°C with an accuracy of up to 0.5°C at +200°C and 1.3°C at -200°C. Thanks to the 1-metre external, waterproof sensor, the logger can remain outside the measuring zone while the probe is placed in the controlled environment. The probe is available in a standard version or a variant suitable for food contact.
The logger sends data via the NB-IoT mobile network, so no WiFi or extra gateways are needed. Configuration is easy via the free mobile app using Bluetooth Low Energy (BLE).
