Colorimetric Reagent Tubes

Colorimetric reagent tubes are devices for instantaneous measurement of gases. They thus measure the concentrations of the gas present quickly (a few seconds) and precisely. This measuring system consists of a manual or automatic pump and reagent tubes specific to the gas to be detected, all forming an integral measuring unit.

It is an attractive solution for measuring the presence of toxic or suffocating gases when a gas detector is not available. Colorimetric reagent tubes allow the detection of a large number of common, rare or exotic gases (approximately 500 gases or vapors).

For some gases there are different measuring ranges to meet individual needs.

See our FAQ page on reagent tubes.

Dosimetric tubes measure the amount of a gas over a period of time (usually 8 hours) to check the average exposure value (AVE) of gases and substances present. They are commonly used to measure concentrations of benzene, formaldehyde, and carbon dioxide in public buildings. They also monitor chlorine, isocyanates (TDI, MDI), mercury, or hydrazine gases in industries.

Small and very lightweight, the dosimetric tubes are supported by a clip that allows them to be placed close to the respiratory tract to make measurements as close as possible to inhaled concentrations. Therefore, they are extremely vigilant and act as “informants” on the total amount of gas inhaled during the shift.

The Pyrotec 840 pyrolyzer is a plug-in module. When gas measurement requires pyrolytic sample preparation to enable detection of chlorofluorocarbons (most refrigerant or freon gases), halogenated hydrocarbons (acetonitrile, methyl chloride, methyl sulfide, etc.) and anesthetic gases With Pyrotec tubes should be used together.

Airtec tubes or Dräger Aerotest systems, breathing air quality related Compliance with EN 12021 standard Particularly suitable for testing. These devices use reagent cylinders and quantitatively measure potentially hazardous substances that may be present in compressed air cylinders (self-contained breathing apparatus SCBA, supplied air systems, breathing air carts, scuba diving, etc.).

They measure carbon oxides (CO and CO2), nitric oxide (NO and NO2), water and oil vapors that may be produced by the air system or compressor and pose a health hazard to the user.
