The maintenance-free, microprocessor-controlled AERASGARD® RFTM – LQ – CO2 – Modbus and RCO2 – Modbus/ RLQ – CO2 – Modbus with Modbus connection, with/ without optional display, in an elegant housing, plastic, with snap-on lid, base with 4-hole attachment, is used to to monitor the entire room climate. For this purpose, measurands air humidity, temperature, CO2 concentration as well as air quality (VOC) are measured. By using a single device to monitor all four measurands, it is possible to effectively monitor and regulate the entire room climate.

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).
