Description
The logger is equipped with a waterproof probe with a Pt1000 sensor which has a very high accuracy in low temperatures.
Efento NB-IoT sensors transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
- Temperature: -200 to +200°C, accuracy: up to 0.5°C in +200°C and 1.3°C in -200°C
- Measurement period: 1 minute – 10 days (configurable by the user)
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Battery ensures up to 5 years of maintenance-free operation
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
- NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.
- Sensor is equipped with 1 m long external probe
