TH-500 Automobile Emission Gas Analyzer adopts NDIR and Electrochemical Sensor to analyze the main component of automobile gas emission: CO,CO2,HC, O2 and NOx.
Instrument Characteristics
1. Test analysis and data management integration. This instrument can store data 300-600 group which can be viewed and print momentarily.
2. Connected onto PC and equipped with special software, TH-500 can realize the PC workstation operation mode. The data can be processed through RS-232 and imported to software of upper computer.
3. Adopting DC-AC. DC can be used into vehicle battery DC12V for power supply directly.
4. Optical components are with long service life.
5. Wide measuring range, the instrument is applicable to motorcycle and various of automobile emission test.
6. Adopting special filtering device to dehydrate and remove dust, which insures gas path far from pollution.
7. Analyzer has printer, which can automatically print the average of test data.
8. Analyzer has USB, so the stored monitoring data can be directly copied into the computer for reference and analysis.
