TH-2007 Zero gas generator

1. provide pure gas that will contain or interfere the elements to be measured. 2.a patent number of 200920173411.5

Applications

Zero gas is the gas that does not contain and interfere with the elements to be measured.

The common used zero gas is the dry air that has removed the interfering elements with the 

elements to be measured. 

TH-2007 Zero Gas Generator is a new model developed by Wuhan Yuhong Environment

Protection Co., Ltd which has a patent number of 200920173411.5. As an ancillary equipment

or the calibration of monitoring and analyzing instrument for TH2000 Ambient Air Automatic 

Monitoring System, it can provide pure gas that will contain or interfere the elements to be

measured. It is used for the TH-2000 Ambient Air Automatic Monitoring System which can

effectively remove water, O3,NO,NO2,CO,HC, methane and non-methane gases. 

Working principle

 The outside air of vapour removed by air compressor is purificated into the purification unit. The purification unit is removed water aganin by obtained patent molecular sieve. The gas dew point which can get to -15°C goes through the patented CO, HC reaction chamber, then passes special three kinds of activated carbon filters. Then all various of air pollutants can be removed effectively.
