SO2,NO2and O2in smoke can be measured
The Environmental Agency of Japan recommends this kit as a means of exhaust gas detection. This kit is in use primarily at such smog generating sources as turbines and diesel engines. The GASTEC SG-1/SG-2 measuring system has been approved for three gases : sulphur dioxide, nitrogen oxide and oxygen.
Sulphur dioxide (5M, 5L), oxides of nitrogen (11HA, 11S), oxygen (31B) * In addition to these substances, there are about 300 types including CO and CO2.
