power consumption: less than 1W co2 sensor linerity output: 0-10V,0-20mA life time: more than 5 years 0-2000ppm co2 sensor

Introduction 

 

 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.

Application:

 

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
