We manufacturers best quality Continous Emission Monitoring System. Gas Sample in flue gases passes through the probe, primary filtration, sampling ball valve and secondary filtration in the chassis, then reaches to measuring cell. After analysis the density and humidity of all components the sample gas will be drained through sampling pump. By controlling sampling ball valve and back-blowing solenoid valve, the system can regularly back –blow to the probe. It can also realize the regular calibration of the analyzer by controlling and calibration solenoid valve.
