Schematic diagram
Zero point calibration
The sensors are pre-set and calibrated at the factory.
Each measuring channel has a separate offset
potentiometer for subsequent adjustment of the
measurement. The adjusting range is ± 10 % of the
measuring range.

2
content
The maintenance-free microprocessor-controlled room sensor with Modbus connection with/without optional display, in elegant plastic housing, with snap-on
lid, base with 4-hole attachment
is an all-in-one device used for detecting all relevant measured values, such as humidity, temperature, CO
2
concentration
and air quality (VOC), thus enabling effective monitoring and control of the entire room climate. It measures CO
2
in the range from 0...5000 ppm, VOC in
one of three selectable sensitivity levels LOW / MEDIUM / HIGH, temperatures in the range from 0...+50°C as well as relative air humidity of 0...100 % r.H.
Relative humidity (% r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. A
digital, long-term stable sensor as a measuring element for relative humidity and temperature guarantees exact measurement results. The air quality is
determined based on a (VOC) mixed gas sensor. The CO
2
content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology).
