ATEX certificate "EU Type Examination Certificate" confirmed according to EN 600079-29-1, EN 50104 and EN 50271.

MSR creates absolute safety for plants and people working in hazardous work areas of ATEX zone 1/2. Taking into account the ATEX directive, gas detectors that comply with the EN 60079-29-1 standard protect against explosion hazards caused by combustible gases and vapours in these areas.

Hydrogen is a very reactive gas, which absolutely requires continuous monitoring by a gas warning system throughout its life cycle. Leaks can occur at any time during research work, on test benches and during the production of the gas, causing catastrophic damage in the event of ignition.

The requirements for ATEX gas sensors for the measurement of combustible gases and vapours include general requirements such as construction and fault indications. In addition, the following are tested, among others: Calibration curve, drift and vibration behaviour, influence of humidity, flow rate or even air pressure.

The product requirements placed on ATEX gas sensors for measuring O2 are described in the EN 50104 Standard. This European Standard considers different types of application for gas detectors. One possible application is, for example, the monitoring of the oxygen concentration with regard to deviations from the normal atmospheric value, both in the case of oxygen deficiency and in the case of oxygen excess. Furthermore, applications are considered in which gas detectors are to monitor low oxygen limit values, e.g. during inerting.

EN 50271 specifies minimum requirements for electrical apparatus for the detection and measurement of combustible and toxic gases and oxygen using software and/or digital technology.

MSR-Electronic offers gas sensors for the detection of methane, hydrogen and propane (in the measuring range 0–100 % LEL, -25 °C to +60 °C) as well as for the detection of oxygen (in the measuring range 0–25 % vol, -25 °C to +60 °C).

Numerous application areas benefit from this, such as the oil, gas and food industries or research with hydrogen.

Further information on MSR Products can be found here in the current MSR-Electronic online catalog or in the webshop:

MSR-Electronic is a manufacturer of fixed gas warning systems with decades of experience in the field of building automation and gas measurement technology. The international company with headquarters in Germany has a wide range of methods for the detection of toxic and combustible gases. On this basis MSR-Electronic develops individual gas sensors, controllers and warning devices for many applications, such as parking garages, tunnels, petrochemical industry or shipping. The products meet more than the general standards and regulations and can therefore guarantee the safety of the plant.
