DESCRIPTION

Air humidity meter with robust aluminium frame / Digit height 100 mm (3.9") /
Temperature measuring range 0 ... 50 °C / Humidity measuring range 0.0 ... 99.9% RH /
Connection of up to four sensors at the same time / Optionally with ISO calibration certificate

The air humidity meter can be connected to up to four external temperature and humidity modules. The temperature measuring range for the sensors of the thermo-hygrometer is 0.0 … 50.0 °C and the humidity measuring range is 0.0 … 99.9% RH. The power supply of the thermo-hygrometer is via a mains connection of 110 ... 220 V AC. The integrated sensor supply can supply the connected sensors from the thermo-hygrometer with 12 or 24 V DC.

As soon as the sensors are connected, they are automatically recognized by the air humidity meter. The communication between the sensor modules and the thermo-hygrometer takes place via an analog 4 … 20 mA signal. If several sensors are connected, the average reading of all sensors is displayed on the thermo-hygrometer. Thus, the thermo-hygrometer is used, for example, in event halls, restaurants or in public buildings to monitor the ambient conditions.

Both the air humidity meter and the sensor module are mounted on a wall. If necessary, the thermo-hygrometer can be mounted on a monitor bracket with the mounting dimensions 75 x 75 mm (2.95 x 2.95"). This allows the thermo-hygrometer to be ideally aligned. The thermo-hygrometer can optionally be equipped with an ISO calibration certificate.
