KwikDraw (Formerly MSA AUER) :Gas Detection Tubes

The combination of KWIK-DRAW™ detector tubes and pumps offers a quick yet precise measuring system to detect hazardous gases and vapours.
The filling material in detector tubes is calibrated and adjusted to the required test gas and will change colour if this gas is present.
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.
