Detector of flammable, explosive, combustible or toxic gases and vapors


Our company offers various types of detectors. These are equipped with semiconductor-, electrochemical- or infra-based sensors, the resistance of which changes as a function of the flow quantity of gas molecules. The changes in resistance are processed and eveluated electronically.

The advanteges of detectors with semiconductor-based sensors are their long service life, unconditional response, ease of handing and last but not least its favourable price. As for their weakness, we should mention their modest selectivity. On the basis of our experiences gathered so far as well as the satisfaction level of our customers, we can recommend these detectors for a wide range of applications. Electrochemical sensors provide greater selectivity but have a limited lifespan. Infrared sensors enable the most modern and selective detection, the only drawback being the currently even higher price.

Our products are continuously innovated on the basis of 30 years of detector manufacturing experiences.

The adjustment of equipments is carried out in compliance with safety standards and sanitary regulations. The sensors have two preset indication levels /WARNING and ALARM/.

In compliance with EU regulations, underground garage gas detectors are calibrated to 4 level evaluation. (the individual level: Level I - 60ppm, Level II - 90ppm, Level III - 150ppm, Level IV -250ppm). On customer’s requirement, we can provide devices with different preset levels.
