HYGRASGARD® AFTM- ⁄ KF TM - LQ - CO2 - Modbus
G
The maintenance-free microprocessor-controlled on-wall or duct sensor with Modbus connection with/without optional display is an all-in- one device used for det ecting all rele vant measured values, such as humidity, temperature, CO and control of the ent ire room climate. It measures C O / HIGH, temperatures in the range from –35...+80 °C as well as relative air humidity of 0...100 % r.H. Relative humidit y (% r.H.) is the quotient of water vapour partial pressure divided by the sat uration vapour pressure a t the respective gas t emper atur e. A digital, long-term stable sensor as a measuring element for relative humidity and temperature guarantees exact measurement results. T he CO sensor (non-dispersive inf ra-red technology). The detection range of the sensors is calibr ated f or sta ndard applica tions such as monitoring residential rooms and conf erence rooms. Room ventilation on an as-needed basis, improved well-being and cust omer benefit, increased co mfor t as well as reduced operating costs through energy c onser vation are just some of the benefits of employing the AERASGARD there are applications for C O crucial fact or in this respect is that both of these measurands are not convertible into each ot her and derivations An NDI R - CO
measuring instrument measures selectively and cannot det ect any VOCs; a VOC mixed gas sensor cannot detec t CO2 molecules.
