The psychrometer can be connected to up to four external temperature and humidity modules. The temperature measurement range at the sensors by the thermometer is 32.0 ... 122.0 °F and the humidity measuring range is 0.0 ... 99.9% RH. The power supply itself is effected in the thermometer via a power supply of 110 ... 220V AC. The integrated sensor can supply the connected sensors in the thermometer 12 or 24V DC supply.

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

Both the psychrometer and the sensor module are mounted on a wall. If necessary, the thermometer can be mounted on a monitor bracket with the mounting dimensions 75 x 75 mm. This allows the thermometer to be ideally aligned. The thermometer can optionally be equipped with an ISO calibration certificate.
