Portable 5 Gas Analyzer

In order a workshop to be complete in terms of diagnosis, a gas analyzer is a necessary tool. Some inaccurate readings in HC or CO could reveal a problem in the engine. AVS offers this equipment in portable form, since most measurements must be done while the vehicle is moving and engine is under load.

The Auto 4-2 & 5-2 portable gas analyzer Series sets new standards in ease of use and comfortable operation. They provide you with the ability to measure CO, HC, O2, CO2, NOx and Lambda (AFR). Weighing just 1 pound, the device fits comfortably in the palm of the hand and achieves with an autonomy of 4 hours, thanks to the rechargeable battery available. It is ideal for diagnosis of pollutants and calculation of values. Compatible with OIML Class 1.
