Gastec GOM-3A Multi Gas Detector

Gastec GOM-3A Multi Gas Detector for Oxygen, Flammable Gas One unit performs two roles, realizing highly efficient and safe control at the same time. Can simultaneously measure oxygen and a flammable gas.

GASTEC Detector indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavour to achieve highest quality detector tubes for analysing airborne gases/vapours, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society. Tubes are now available for more than 500 different applications.
