Gastec Polytec Tubes

Gastec Polytec Tubes

Polytec tubes are used in situations where it is unknown which hazardous gases are present. The Polytec tubes take a number of measurements to determine present hazardous substances.

The Polytec tubes are commonly used by firefighting HazMat teams or occupational hygienists going into a situation where they need to quickly establish which gases they are faced with, take a quick reading then use the correct gas detection equipment.

The Gastec Polytec system consists of the Model GV-100S Gas sampling pump and the Polytec tubes.

The Gastec Polytec tubes are unique detector tubes, each having 1 to 8 reaction layers to determine multiple unknown substances in the sample simultaneously. When you pull the handle of the Pump and wait for a predetermined sampling time, the colour (s) of the Polytec tube’s layer (s) change uniquely according to the contents of the sample.

Five types of Polytec tubes are available: Polytec I (No.107), Polytec II (No.25), Polytec III (No.26), Polytec IV (No.27), Polytec V (No.28) and Qualitative tubes for fire investigation (No.108). Detailed descriptions are given in the instruction sheets included with individual Polytec tubes.
