ZG-100 Zero Gas Generator

Description

At present, daily calibration or zeroing process before vehicle measurement of exhaust gas analyzers in some detection station will use ambient air for zeroing, not completely meeting purity requirement of zero gas(especially for NO detection based on infrared principle, which will exists oisture interference). In addition, some other detection ststions use zero gas for zeroing but the amount is too large, which increases operation cost of detection. The zero gas prodeed by generator meets the purity requirement and can replace zero gas cylinders to minimize operating cost.

ZG-100 Zero Gas Generator Smoke meter consists of external oilless air compressor(optional), pressure & flow controller, water removal system, NO & NO2 remover, etc. It is based on condensation and molecular sieve adsorption filtering method to remove factors that will affect calibration of exhaust analyzer and output dry and clean gas.
