Temperature and humidity indicator for ambient monitoring, measures 32-122 deg F and 0-99.9% RH

The thermometer 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 deg 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 thermometer. 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 thermometer 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.
