The colorimetric gas detection tube system is a simple and accurate solution composed by a manual sampling pump and a specific gas detection tube. They are designed for use together.
Accurate: the sampling pump features a mechanical accuracy piston which creates a vacuum then enables direct reading on the colored tube (colorimetric tube)
Swift: one or two pump strokes are enough to draw sample and the value can be directly read on the tube
User-friendly: no knowledge, no specific process and no technical competence are required
