Wireless thermometer, hygrometer, barometer for external probe, Sigfox IoT

code: W7811

The wireless sensor measures temperature, humidity and pressure from external sensor on the cable (not included). It features a simple, compact design and is positioned directly in the measured area.

Measured values are displayed on the display and are regularly sent, in an adjustable time interval from 10 min to 24 h, by radio transmission in Sigfox to COMET Cloud. After  the emergence  of  a  new  alarm  (or  the  extinction  of  an  alarm  in progress),  an  extraordinary  alarm  message  is  sent  at  the  latest  within 10 minutes.

The temperature and humidity probe is not included in delivery, probe of the appropriate length and design you can choose in optional accessories.

 

The wireless meter includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

Included in delivery:

Radio configuration zone RCZ1. More information about Sigfox Radio Configurations (RC).
