The industrial wall mount CO2 Sensor & Controller is designed for fast & accurate measurement of CO₂ level, humidity and temperatures of air, dew point and wet bulb. It monitors CO₂ concentration level and can controls ventilation system such as air conditioning to operate only when its necessary without the need for occupant intervention. With CO₂ Monitor & Controller you are ensured with a healthy workplace requiring minimum energy consumption while simultaneously maintaining Indoor Air Quality (IAQ). It has 100V-240V power input and Power Adaptor with US, UK, Australian and European plug.
Themeter is designed with a built-in relay, which can be connected to an IndoorAir Quality (IAQ) system to control the opening andclosing of the system. It also allows you to set 2 limits,upper limit or the maximum CO₂concentrationand the lower limit or the normal CO₂concentrationlevel. In addition it also has an audible & visualalarm that gives warning whenever the CO₂concentration level exceeds the limit and will onlystop when CO₂ goes back to normal level ora key has been pressed.
Forexample, the main unit is connected to a ventilationsystem (eg: air-conditioning). When CO₂readings goover the upper limit, beeps will heard, LED light willbe flashing and the relay will automatically turn onand sends an output signal so the fan will be turn on.And once CO₂reading fall under the lower limit or reachesthe normal CO₂concentration, the beeping will stop,the flashing will stop and the relay will send out anoutput signal again to close or turn off the fan.
Whenthe unit gets a high reading of CO₂and there is noventilation system attached, the user will notifiedvia the beeping alarm and flashing LED light and willautomatically stop once CO₂ concentrationgoes back to its normal level or a key has been pressed.
Inaddition, it has PC Link that can send gathereddata directly to your PC for on-line logging and dataanalysis via the optional RS-232 interface andsoftware (not included in set).
Areasof Application:
Hospitals, Offices, Schools, Theaters, Indoor SportsArenas, High Rise Buildings, Indoor Area Quality, CommercialBuildings, Residential Housing, Public Buildings, DemandControlled Ventilation, Clean Rooms.
Poorindoor air quality in rooms can lead to fatigue, lackof concentration and illness (Sick Building Syndrome)due to high concentration of CO₂ level.
