The Draeger X-AM 2500 Gas Detector is a specially developed gas detector featuring a combustible gas Ex sensor for Zone 0 which has a high resistance to silicone and hydrogen sulphide. This 1 to 4 gas detector reliably detects combustible gases and vapours, as well as O2, CO, NO2, SO2 and H2S. The X-AM 2500 displays constant gas level readout on a large, clear screen, perfectly suitable for confined space entry.
