Drager Gas Detectors – Portable & Fixed Gas Detection

Drager Gas Detectors

Gas Detectors & Sensors

Drager gas detectors, sensors and detection equipment (portable and fixed) are used for monitoring a wide variety of flammable and toxic gases in many industries.

Portable gas detectors protect workers while fixed gas monitors provide plant detection of harmful gases all year round.

Drager gas detectors help to save lives and protect plant by early detection and notification of toxic and flammable gases in industrial and hazardous area industries, with ATEX and IECEx.

Since 1889, Drager has been researching and developing the most innovative gas detection equipment in order to provide the highest level of industrial performance and safety in industrial and hazardous area industries – providing an early warning defence against toxic gas inhalation and the hazards associated with gas leaks.

Drager gas detectors are in operation in over 190 countries globally and can provide a solution for almost any gas detection situation within any industry. The mission statement set out by the company is “Technology for Life” which is their guiding principle.

Drager gas detectors and detection equipment is separated into two categories – fixed and portable. They are simply as their name suggests, portable (personal) and fixed (plant) detectors which are specified dependent upon industrial processes which produce toxic and flammable gases or vapours.

Drager gas detection equipment has been used in many industries in many forms for over 100 years and still provides the most cutting edge, reliable and safe gas detection, monitoring, protection and warning.

Without the use of detection monitors serving as an aid, humans are unable to detect the presence of many gases which can be extremely harmful and even fatal. One example of this is hydrogen sulphide (H2S) gas which can be detected by humans in low concentrations due to the distinctive rotten egg smell.

In high concentrations however the hydrogen sulphide gas cannot be detected by smell which can be fatal and escaping into areas that are assumed as safe can be equally as dangerous as the gas cannot be smelt.

Even non-hazardous gases such as argon, helium and nitrogen can become dangerous as they displace the oxygen in the atmosphere leading to a personal suffocation risk. The protection of any working area depends entirely upon the quality of the gas detection system and the correct specification and selection of gas monitors into these areas.

Polytron 8700 – Fixed Gas Detector


Drager Polytron 8700 fixed gas detector is a permanent gas detection device that is hard wired and fixed in place within a potentially hazardous working area to provide constant, 24 hour gas detection.

Polytron 8700 offers quick and reliable detection of hazardous gases and vapours and the microprocessor features a new, innovative IR sensor with drift free and resistant optics – the gas detector also offers simple management with the digital communication display.

Remote access is also available using the Polysoft 8000 software for quick and convenient evaluation of the instrument status. In addition it is possible to integrate the Polytron 8700 into existing management systems using DTM. Polytron 8700 also has two mounting options and contains a library of over 100 gases that can be detected.

Hazardous Area Zone 1 & Zone 1

The correct gas detection equipment is vital in any working conditions and industry – within hazardous areas, the correct selection of gas detection depends on several factors. Identification of gas risk is essential to the safe specification of a gas detection system :

  • What are the potential worksite hazards?
  • What alarm time is most appropriate given the gas hazards present?
  • Does the project require portable or fixed gas detection?
  • What environmental conditions must the detection system withstand?
  • How do my employees work best and what type of gas detector will allow for ease of use?
  • Do we need to look at a single worksite or multiple locations?
  • What training will be most effective for my employees?
  • What classification of hazardous area equipment is required?

3 categories of gas detection that must be detected reliably in order to protect human life, assets and the environment :

  • Ex – risk of explosion by flammable gases in Zone 1 or Zone 2 hazardous areas
  • Ox – oxygen; risk of asphyxiation by oxygen displacement or risk of increase of flammability by oxygen enrichment
  • Tox – risk of poisoning by toxic gases

Infrared gas detector PIR 7000 

Drager PIR 7000 is a SIL 2 approved explosion proof infrared gas detector for the continuous monitoring of flammable gases and vapours in hazardous area and safe area offshore locations.

Early gas detection can mean personnel have enough time to take the correct action and put the right safety procedures in place. For many industries and people working within hazardous areas the threat of gas leaks is a daily challenge that must be planned for in advance.

Portable & Fixed Gas Detectors : Drager PIR7000 – SIL 2 explosion proof infrared gas detector for continuous monitoring of flammable gases and vapours in hazardous areas.

Explosive atmospheres can be caused by the presence of flammable hazardous gases and vapours being released into the atmosphere which are often undetectable by humans without the use of auxiliary gas detection equipment.

Industries such as oil and gas, petrochemical and power are likely to have Zone 1 and Zone 2 hazardous areas where an ATEX or IECEx certified gas detector (flameproof) should be used.

When selecting the correct gas detector there are many factors to take into consideration in order to make sure the correct detector is installed and it is safe and will perform the task as expected.

First, it is vital to fully evaluate the working area and decide whether a fixed or portable gas detector is necessary. A fixed gas detector provides constant detection and can give early warning signs, however a portable gas detector can be easily carried around from zone to zone.

Furthermore, other points to consider include the types of gas likely to be present, the levels of concentration, whether the detector is point or open path and the presence of any other gases that may affect the reading.

Flammable gas detectors improve safe working practices – used to trigger alarms if a specified concentration of the gas or vapour is exceeded. Early warning of gas exposure levels provide improved worker safety. Typical work tasks include :

  • removal of flammable materials from tanks and pipes in preparation for entry, line breaking, cleaning or hot work such as welding
  • evaporation of flammable solvents in a drying oven
  • spraying, spreading and coating of articles with paint, adhesives or other flammable solvents
  • manufacture and storage of flammable gases
  • manufacture and mixing of flammable liquids
  • solvent extraction processes
  • gas or oil combustion
  • combined heat and power plants
  • heat treatment furnaces in which flammable atmospheres are present
  • battery charging
