Gas in potentially explosive atmospheres – SG350ex and SG5100ex

gas cylinder

The GSA measuring devices SG350ex and SG5100ex have been specially developed and certified for use with gas in potentially explosive atmospheres with the suffix “ex” .

When it comes to measuring occupational safety in such a hazardous environment, it makes sense to use the GSA SG350ex or SG5100ex measuring device if contact with flammable gases is possible.

Cyclone in GSA measuring device FSP2 for dust measurement

FSP cyclone FSP2

GSA ‘s FSP2 personal sampling system is equipped with a cyclone. This is a licensed sampling system that is used, for example, for particle measurements of dust fractions of A-dust or E-dust at the workplace in order to determine the dust load there.

Measuring dust exposure at the workplace is always useful when occupational limit values must be complied with.

GSA room air measuring devices detect solvents

Solvent indoor air measuring-devices

GSA SG350ex, SG5200 and SG5100ex room air measuring devices for sampling solvents

GSA indoor air measuring devices reliably detect the presence and harmful quantities of solvents in the home. If, for example, an unpleasant odor develops in the course of new furniture or other furnishings, or if symptoms only occur in one room, there may be solvent pollution.


The GSA measuring device SG350ex is particularly suitable when it comes to escaping gases. These room air measuring devices therefore provide more information about the gases present in the room under investigation.

Wood preservative test with PM4-2

Wood preservative test with GSA measuring devices PM4-2

A wood preservative test is advisable if a health hazard is suspected. The GSA measuring device PM4-2 is recommended for a wood preservative test.

The measuring device PM4-2 can provide meaningful measurements due to its relatively high air flow rate, even at locations with low levels of pollution.

After the wood preservative analysis, you can be sure whether there is a potential risk to health. Our measurement technicians will be happy to create a customized measurement concept for you.

Measure asbestos fibers with SG12

Asbestos fibres wall

Measure asbestos fibers with measuring device SG12 to determine health hazards

The measuring device SG12, specially developed for asbestos measurement, can be used to precisely measure even very low concentrations of asbestos fibers. It is suitable for sampling inorganic fibrous particles in accordance with VDI 3492 and ISO 14966 as well as asbestos or AMF. It can also be used to measure the various dust fractions such as A-dust or E-dust.

An analysis of asbestos is then carried out to determine the concentration of this hazardous material in the building.

If it is suspected that material containing asbestos was used in the construction of buildings, a measurement is advisable.

The GSA Messgerätebau GmbH manufactures its own suitable measuring devices for measuring hazardous substances. In addition, every asbestos hazard situation is unique. For this reason, we are happy to develop a suitable measurement strategy for sampling asbestos for you.

Testing mold infestation

Testing mould infestation

Testing for mold infestation is often a necessity

In order to obtain clarity about a mold infestation situation, a precise analysis of the mold infestation should be carried out. In addition to self-testing, a professional analysis after testing can provide precise results that often initiate further important measures. GSA Schadstoffanalytik carries out this precise analysis after sampling for mold infestation testing.
