Gastec Detector Tube - Hydrogen Sulphide High Range (10-4,000 ppm), 10 Tests

A detector tube system that performs measurements using the GV-100/GV-110 gas sampling pump. The handle on the gas sampling pump is pulled all the way back to create a vacuum inside the cylinder, drawing the gas sample through the detector tube. This can be used by anyone, anywhere, and at anytime to quickly and easily make an accurate concentration reading. GASTEC Detector Tubes indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavor to achieve highest quality detector tubes for analyzing airborne gases/vapors, as well as pollutants in soil and water through our advanced state-of-the-art research and development.
