This portable unit is lightweight, rugged, and capable of on-the-spot, precise detection of numerous gases and vapors

• Measures gas and vapor concentrations in work area as easily as reading a thermometer
• Calibration marks indicate gas concentration
• Synthetic rubber sheath allows pump to be held firmly, even with wet gloves
• Fail-safe handle locks in two positions (50 or 100cc)
• Flow finish indicator makes viewing instantaneous and easy

Also available are hydrogen sulfide detection tubes with various measuring ranges for quick, accurate, and quantitative detection. The reagents in the detection tubes contain fine-grain silica gel, activated alumina, or other absorbing media inside a constant inner diameter, hermetically-sealed glass tube. Reagent will change color as it makes contact with the gas. Length-of-stain indicates quantitative results.

System uses a high-precision, piston-type, volumetric pump and reliable, direct-reading detection tubes. Just insert tube, pull pump handle, and tube changes color.
