Gastec GOA-40D-5 Hand-held oxygen detector

Gastec GOA-40D-5 Hand-held oxygen detector can quickly and accurately measure oxygen concentrations at a variety of different work sites subject to host of complicated and varying factors.
All come with a high performance galvanic cel sensor.

Fresh air contains 21% oxygen. Lower concentrations can cause unconsciousness and may even become life threatening. Since oxygen is colourless and odorless, human senses cannot detect changes in concentration levels.

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.
