Product Description


 ACO2 is a kind of easy install, low cost co2 sensor. Specially design for building automation and other places where needed co2 detecting. Measure density of co2 in the air, measurement range is 0-2,000ppm. With linerity output: 0-10V,0-20mA.  ACO2 is for energy conservation and improve indoor air quality.




ACO2  is specially designed for ventilation control in building automation. In this application, indoor co2 level can be achieved interior of the fresh air requirement.

Adjust the fresh air requirment accoding to the indoor people.

Engergy conservation





• CO2 measurement: 0-2,000ppm CO2

• Output Signal:

OUT 1: 0-10V

        OUT 2: 0-20mA

• Low cost design, best choice for DDC control

• non-specific application enviroment no need calibration





24V AC/DC (+)






lineary voltage output, 0-10V correspond 0-2000ppm



Lineary currancy output, 4-20mA correspond 0-2000ppm
