Automotive Emission Analyzer

The MEXA-584L simultaneously measures CO, HC, CO2 (non-dispersive infrared: NDIR) and air-to-fuel ratio (AFR) or excess air ratio (A) in idle state. lt optionally measures O2, NO, engine speed (RPM) and oil temperature (TEMP). Lightweight and compact with a clear LCD and effortless operation, it can be used as a simple measurement instrument in any work situation.
