Multifunction Indoor Air Quality

A single device to monitor all four measurands humidity, temperature, CO2 concentration as well as air quality (VOC).


Taishio Multifunction IAQTransmitter AQ-TSRCO2 with Modbus connection, with/ without optional display, in an elegant housing, plastic, with snap-on lid, base with 4-hole attachment, is used to monitor air humidity, temperature, CO2 concentration as well as air quality (VOC) are measured. A setpoint potentiometer is optionally available as an operating element. By using a single device to monitor all four measurands, it is possible to eectively monitor and regulate the entire room climate. It measures CO2 in the range of 0…5000 ppm, VOC at one of three selectable sensitivity levels LOW / MEDIUM / HIGH, temperatures in the range of 0…+50°C, as well as relative air humidity from 0…100 % r.H. A digital, long-term stable sensor used as measuring element for relative air humidity and temperature guarantees exact measurement results. The air quality is determined based on a (VOC) gas mixture sensor. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology).
