The NB-IoT wireless high temperature logger is designed for accurate temperature monitoring in environments with extremely high temperatures. This data logger is ideal for applications such as bakery ovens, industrial drying ovens and production processes requiring constant high temperatures.
The logger measures temperatures from -70 to +450°C with an accuracy of up to 0.3°C at 0°C and 1.8°C at +300°C. Thanks to the 1-metre external Pt1000 sensor, the logger can remain outside the measuring zone while the probe sits in the hot environment.
The logger automatically 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).
