Protecting from the invisible danger: gas detectors from Compur Monitors

We focus on your safety

Nothing matters more to us than your safety. As a medium sized company we are particularly close to our customers. Finally our mission is to provide gas detection for your safety.

In this context our entire team stands for first class advice, first class products and first class service.

gas detectors usage

Gas detectors must be installed wherever legislation or local safety standards require to monitor potentially dangerous atmosphere. As soon as the alarm threshold limit is exceeded, they generate a visible and audible alarm. This helps to increase as well plant as personal safety and industrial hygiene. Professional health and safety protection contributes to protect the environment and reduce cost. Any identification of a leakage is significant cost reduction in terms of building, plant, cooling or heating, as well as absence due to illness.  In any respect the operator of a plant is responsible for its safe and reliable function. Seamless industrial standard gas detection is an important tool to achieve this.

Examples for fixed systems:


Statox 505

The stationary gas detection system compliant with SIL 2 srandard

Statox 503

The fixed gas detection system for toxic and combustible gases. The Statox 503 Controller operates with 4 – 20 mA transmitters as well as with catalytic sensors.

It complies with SIL 2 requirements, even if operated as stand - alone unit. Therefore it can also be used with frontends of other suppliers.

Statox 501 Infratox

The fixed gas detection system for combustible gases uses the infrared absorption method of gas detection. It features on site display and non intrusive one- man calibration. The reliability of this system is unmatched. The measuring range varies from ppm to % LEL.

Statox 501 IR LC

The low - cost version fixed gas detection system for combustible gases uses the infrared absorption method of gas detection in. The Statox 501 IR LC sensor heads are backward compatible to systems using catalytic sensors. They can be used to upgrade such systems without replacing existing hardware.

Frequently asked questions

Are the gas detectors protected from explosions?

Yes, all of our gas detectors have a pressure-proof encapsulation which means they are intrinsically safe thereby contributing to a higher degree of safety. Even in case of an imminent gas explosion or one that has already occurred, you can trust in your gas detector without reservation.

Do they test the general limits of toxic gases, e.g. HCN, phosgene or VOC ?

Yes, one gas detector in our range also detects toxic gases. Potentially poisonous gases can be measured in both ppm range and the ppb range.

Do you measure combustible gases in the LEL range, i.e. the lower explosive limit?

Yes, our gas detectors are designed exactly for these types of measurements. With the integrated display of the devices, you will obtain an overview of the area of the LEL in which a gas leak has occurred or is occurring with a range of 0 to 100 percent.

Do you have any sensors based on the principle of infrared absorption?

Yes, every gas detector is equipped technically accordingly. With this, our gas detectors are also suitable for measuring hydrocarbons and carbon dioxide in the ambient air of your company.

Do the gas detectors have electrochemical sensors?

Yes, with the right equipment, a gas detector we have produced also allows inorganic, toxic gases to be measured. Just as with the toxic gases mentioned above, measurement accuracy in both the ppm range and the ppb range is assured.

Is it also possible to use the gas detectors in the field of plant safety?

Our gas detectors are, of course, also suitable for this application and make a valuable contribution to safety in your company. You may rest assured of an exact measurement and inspection of toxic and non-toxic gases which may escape from your plants or factory machinery in this area as well.

The right gas detector for any gas and any application

Compur Monitors is manufacturer of high – end gas detectors, as well fixed and portable. Most instruments comply with functional safety requirements level SIL 2. Highly sensitive and specific sensor technology make sure that no deviation in ambient air quality can endanger the health of personnel or the environment. Highly specific sensors reduce the risk of false alarms to zero.  Elaborate selection and positioning of gas detectors protect the ambience in the chemical, energy, pharmaceutical, food and oil industry, but also in greenhouses, wastewater treatment, drinking water supply, airports, hospitals, malls and machinery compartments. We the manufacturer of gas detection systems provide best accuracy of measurement in the LEL as well as in the ppm or even ppb range. No matter if you need to detect toxic gases, combustible gases, VOC or even multiple gases simultaneously, we provide the appropriate sensor technology: catalytic, (Cat) infrared (IR), photoionization (PID) or electrochemical (EC).

Important: Sensor positioning

Stationary gas detectors monitor hazardous areas around the clock. As point monitors can only detect gas in their vicinity, it is important to position them in a strategic manner: Close to potential leakages such as valves flanges, pumps and vessels, but also spread well in the plant. Sensors for gases with higher specific density than air should be placed close to the floor (protect from rain splash - back!), sensors for gases with lower density should be located close to the ceiling. Our instruments feature high intrusion protection ratings, so that they can be used as well indoors as outdoors. Perfect personal protection gives the multi gas detector Micro 5. Its sampling system can aspirate gas from a distance of more than 20 m.

The lifehood of gas detection is functional safety

Gas detector must be proof – tested or calibrated in regular time intervals by trained and authorized personnel. We provide useful tool for bump – testing, such as the Compur gas generator, but also appropriate calibration equipment and accessories. The latest member of the gas detector family is the Statox 560. With its built – in gas generator it can perform an automatic self - test every 24 hours. In case of a problem, our instruments will generate an alarm with absolute reliability.
