Description

The device measures temperature and CO2 concentration from internal sensors.

The measured values ​​are sent at an adjustable time interval (10 min to 24 h) by radio transmission on the Sigfox network to the COMET Cloud, from where the user can view them using a personal computer or mobile device.

The instrument can monitor up to 2 alarm limits of the measured variable. Exceeding these limits is indicated by sending an emergency message. COMET Cloud transmits this alarm message by email to the selected user. The device is suitable for applications that tolerate the delay of the information delivered by Sigfox (maximum 10 min).

Highlighted features:

Wireless transmission of measured values ​​and alarm states
Two battery slots for longer operating time
Battery powered (size C 3.6 V) with low battery indication (battery life up to 7 years)
Input for external power supply
Remote configuration of the device from COMET Cloud (maximum once per day)
IP20
Traceable calibration certificate according to EN ISO/IEC 17025
