| Specification: | Model: Four GAS Description
Autochek Model 4/ 5 is a portable automobile exhaust gas analyzer that uses single beam, non dispersive infrared( NDIR) determine CO, CO2 and HC concentration, O2 and NOx are detected by electro-chemical sensors.
Autocheck 4/ 5 also calculates LAMBDA and AFR ( Air Fuel Ratio) and exceeds the performance requirements of ASM/ BAR 97 and OIML Class 1& 0.
The Korean government Approved No.OEC-Lamda-2000-2, Patent pending
