Detect Unknown Gases

In many situations on-site or at the scene of an incident, determination of potential air borne contaminants is critical. To identify a wide range of chemicals with just one tube and a pump stroke, use Gastec Polytec tubes from A1 Cbiss (UK) – Eliminate the need for using multiple numbers of standard Gastec tubes.

Gastec Polytec detector tubes can be used at the scene of an incident by rapid response teams to provide the detection of multiple unknown substances by a single test of air quality and toxic levels.

They are also ideal at sites such as tanker crashes, chemical spills and building fires to prevent further escalation and injury to rescue personnel.

This type of gas detection tube is a cost effective solution ideal for any newcomers to gas detection or for those looking to identify which gas they need to detect in the long-term. It could also be used by existing users of traditional technologies looking for an alternative method of detection.

Polytec tubes simultaneously measure up to 15 gases during a single test, providing cost-effective monitoring and chemical identification.

Gas detector tubes are used with a handheld air sampling pump. The pump utilises a piston design. The pump connects to one end of the gas detector tube and the user draws a sample of 100ml of ambient air per pump stroke.

As the gas sample works its way up the tube towards the pump, it reacts with the chemical reagent within the tube such that the change produced is proportional in length to the concentration. By using the calibration scale printed on the tube, the concentration may be read immediately, without the need for laboratory analysis. The point where this reaction stops is easily read off against markings on the detector tube.
