GASTEC CORPORATION - For all types of gas and vapour

Flue gas measuring kitSG-1/SG-2

SO2,NO2 and O2 in 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.

  • Measurements of SO2,NO2, and O2, in smoke and soot
  • Measurement is completed in less than 60 seconds, enabling the measured results to be known on the spot.
  • No special technology, knowledge or skill are required.
  • Excellent repeatability. The difference in results obtained by different persons is small.
  • Both the initial cost and running costs are low, and maintenance is unnecessary.
