Cosber Industrial | Emission Gas Analyser

Emission Gas Analyser

The KWQ 4/5 Automotive Emission Gas Analyzer be made in our company that is designed to measure the concentration CO, CO2 and HC by using non-disperse infrared (NDIR) method and to detect O2, NOx by using electrochemical cell method. The bench is import from Japan and the sensors are import from UK.

Be sure to read this Manual before using the KWQ 4/5. Store this manual safely so that it is readily available whenever necessary.

Trolley For Emission Gas Analyser
