KwikDraw detector Tubes formerly known as MSA/AUER detector tubes are a reliable method of testing more than 200 hazardous gases and vapors. A sample is drawn by connecting the detector tube to a special bellows-type pump that draws a known volume of air with each stroke. The Sensing Chemical in detector tubes will change color if target gas is present in the sample air. The length of this discoloration indicates the concentration of the hazardous gas or Vapour and can be measured by a printed scale on most of the tubes.

KwikDraw Detector Tubes are pre-calibrated and provide quick, economical monitoring for wide range of various Toxic and Hazardous gases. The Kwikdraw Deluxe pump and Gas Tester II offer automatic stoke counter with unique end of stroke indicator.
