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

TECHNICAL DATA

The instrument measures the temperature and humidity of the external probe.

Integrated atmospheric pressure sensor.

It has a simple and compact design and is positioned directly in the measured area.

The measured values ​​are displayed on the screen and are sent regularly, in an adjustable time interval (10 min to 24 h), by radio transmission from Sigfox to the Cloud.

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

The device includes a traceable calibration certificate with declared metrological traceability of standards based on the requirements of EN ISO / IEC 17025.
