Term Main definition
In gas detection, a device that draws an air sample into a detecting agent (colorimetic gas sampling tube or gas detector). Colorimetric gas sampling tubes require a pump, manual or electronic, to draw a sample through them. For electronic gas detectors, pumps can be integrated, clip-on or hand aspirators. Gas detectors with an integrated pump are suitable to sample confined spaces for gas hazards through a sampling hose. Photo Ionisation Detectors (PID) should always be equipped with a pump. A pump generally shortens the response time to gas hazards, but also consume electricity, shortening the battery life.


7Solutions has its own service and maintenance department where we can service any gas detection instrument, no matter what brand or age.
