NAPRO PC-Multigás Gas Analyzer

Complete emissions diagnosis in one compact unit

The PC-Multigás is a compact, portable automotive gas analyzer developed and manufactured by NAPRO. It uses non-dispersive infrared (NDIR) technology for simultaneous measurement of the main exhaust gases, and is suitable for diagnosing gasoline, ethanol, CNG and flex-fuel engines.

It can be powered by the vehicle's own 12V battery or from the mains (110/220V), allowing measurements to be taken with the vehicle in motion using a laptop.
