Specifications
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
