The device measures the temperature and humidity from an external probe on the cable - you can choose it from an optional accessory. In comparison with sensor W3811 the sensor W7811 is additionally equipped with an internal sensor of atmospheric pressure. The sensor is characterized by a simple and compact design with the possibility of installation directly into the measured space. Model with external cable probe is also suitable for measurements in areas where the risk of poor reception sigfox. The probe can be placed at the measurement point and the device itself where is able to reach a better signal. The probe length must not exceed 30 meters. The probe can be used with a suitable sensor cap even in more demanding conditions.

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 via e-mail to the selected user. The device is suitable for applications that tolerate the delay of information delivered by Sigfox (max. 10 min).

Highlights:

• wireless transmission of measured values and alarm states
• battery power with low battery indication (battery life 4 months to 7 years)
• external power with optional accessories
• remote setting of the device from COMET Cloud (maximum once a day)
• IP65
• traceable calibration certificate in accordance with EN ISO / IEC 17025
