Colorimetric Reagent Tubes

Colorimetric reagent tubes, It is particularly suitable for spot measurements of gas or where conventional devices are not available to detect or measure certain substances. It is simple to use, accurate and economical. They do not require any special technical skills. In industry (for exotic or rare gases reagent tubes ) and in the tertiary sector (to measure pollutants passive badges or smoke tubes air flow detectors using ) can be used.

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

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.

Pyrotec tubes for the detection of Freons and Anesthetic gases

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.

Area Gas Monitor

Area tracking devices It concentrates the advantages of a fixed detector in a portable, robust and easy-to-use device. They aim to protect response teams in “gas” risk areas during limited-term development or maintenance work. They have a very long autonomy, up to 100 days for some, and can be interconnected to secure very large environments (oil depots, tunnels, pipelines, etc.).

Field gas monitor: Technical advantages

Unlike portable gas detectors, which are Personal Protective Equipment (PPE), field monitors are collective protective equipment that secure a defined area where several individuals can evolve. These are multi-gas detection equipment that are heavier and more robust than individual detectors, but are easy to transport and implement.

These vehicles, which have a very long autonomy of up to 100 days for some, are often used during technical stoppages in the chemical and petrochemical industries, during the construction or renovation of public works (tunnels, earthworks, drilling), during sewerage or interventions in narrow spaces (sewage, manholes). They are found.

In addition to their large size, field monitors offer many technical advantages: the warning performance is often comprehensive, with strong sound alarms from 100 to 120 dB and a light signal that is visible from a distance and 360°. Some even feature customizable action messages such as “Ventilate” or “Evacuate”, thus strengthening the safety device in case of risks associated with the presence of gas.

Field monitors: gas detected

The most common configurations are 4-gas (explosive gases, O2, CO, H2S), 5-gas PID (explosive gases, O2, CO, H2S, VOC) or 6-gas tunnel (CO, CO2, NO, NO2, O2, SO2).

Various configurations are possible , among them AsH3, B2H6, Br2, Cl2, ClO2, CO, CO2, F2, H2, H2O2, H2S, HBr, HCl, HCN, HF, HNO3, NH3, N2H4, NO, NO2, O2, O3, PH3, SiH4 , SO2 gases as well as all VOCs (acetylene, benzene, butadiene, ethanol, ethylene, isobutylene, ethyl acetate, ethylene oxide, perchlorethylene, styrene, toluene, xylene) and explosive gases (natural gas, LPG, hydrocarbons, alcohols and solvents). There are measurement cells for ).

For calibration, periodic checks or gas testing of gas detectors, we offer a wide range of calibration gases in disposable cylinders complying with the ISO6142 standard.

Portable Multi Gas Detector

Portable multi gas detector It can detect up to 7 gases simultaneously and is available in diffusion mode or with a gas sampling pump. It is a must-have item for operators working in harsh environments. The most widely used model, mainly found in sanitation, steel industry, public works and indoor applications It is a 4 gas detector (explosive gases, O2, CO and H2S).

Portable multi gas detector

A multi-gas detector can measure concentrations of many different explosive gases, volatile organic compounds (VOCs), freons, and many toxic gases. Compact in size for low weight but at a higher cost than a single gas detector , it offers much more detailed features. It can archive gas concentrations or alarms and calculate average and limit values ​​of exposure or traceability of events.

It may include accessories such as a gas sampling pump for access authorization measurements or leak searches in confined spaces (sewers, manholes, tanks, etc.).

4 gas detectors

It is one of the most widely used portable 4-gas detectors in the industrial sector (metallurgy, steel production, petrochemical), public services (construction, drilling) and water treatment sector. Offering good value for money, this device simultaneously detects explosives (natural gas, LPG, hydrocarbons, alcohols and solvents), H2S, CO and O2 deficiency. We recommend performing a daily crash test before each use to check that the sensors and device are working correctly. This device continues to be a favorite in the sanitation and tight space working industry. It is also recommended (and mandatory) as part of CATEC training (certificate of proficiency in working in confined spaces) to protect against the following risks:

  • Asphyxia, anoxia or hypoxia: temporary or permanent lack of oxygen
  • Poisoning: Inhaling or absorbing toxic substances such as hydrogen sulfide or carbon monoxide
  • Explosion and fire: Flammable methane can cause fire and explosion

Gas detection area monitoring

They are also called field monitors or area monitors, which are larger in size than traditional portable gas detectors. These are field protection devices, not personal protective equipment. Therefore, field monitors provide accurate gas detection within a defined environment. Workers can move safely within the gridded area (see ” LENS Wireless technology “).

“All-inclusive care” concept

Almost all of our products that detect four or more gases are available with the “2-year maintenance included” option. This innovative concept includes calibration and periodic sensor maintenance for two years from the date of purchase (about a hundred euros for a conventional 4-gas device). At the end of these two years, it will be possible to renew this service for another two years and so on…

In addition to this option, companies should regularly perform on-site crash tests to check that the detector is working correctly before each new use, especially when operating in tight spaces.

It is compact and lightweight, and can be placed at respiratory tract level without impeding the user's mobility. It is suitable for industrial operating situations such as explosive gas detectors (explosimeters) as well as for the tertiary sector, for example as CO2 detectors or oxygen deficiency detectors (oxygen meters).

waste gas detector

Once it is opened we can no longer turn it off. Disposable gas detector It works continuously for two years. It is as simple and effective as a traditional (non-disposable) single gas detector. The biggest advantage of the disposable gas detector is that it requires almost no maintenance. On the other hand, after two years the device shuts down permanently and becomes unusable.

Disposable gas detector It is mainly used as an oxygen meter (oxygen deficiency detector), hydrogen sulfide (H2S) detector or carbon monoxide (CO) detector. However, they can also be used for ammonia (NH3) or nitrogen dioxide (NO2). To evaluate concentrations of other gases it is necessary to switch to a non-disposable gas detection device.

Portable single gas detector

This personal protective equipment is battery-operated or rechargeable and has more elaborate functions than a disposable detector, for example archiving measured concentrations and alarms. This security device has a much longer lifespan than a disposable detector. It therefore requires daily crash testing, regular calibration and periodic checks.
