Gas Leak Detector for Hydrogen (H2)

Handheld gas leak detector for the selective detection of hydrogen (H2). Specific metal-oxide(MOX)-semiconductor gas sensor element (GGS 1000 and GGS 6000 series). Flex arm between device and sensor head (length 300 mm / standard). Display of the detected H2-concentration value from the lower ppm-range up to the LEL 4 Vol% H2 (LEL... Lower Explosive Limit). Automatic switching of detection range. Additional linear, cumulative display of the level of the detected concentration values up to 10000 ppm / 1 Vol% by bar graph (20 steps/ segments, from left to right) on LCD. Display of reached or exceeded concentration threshold values (≥ 10 ppm, ≥ 100 ppm, ≥ 1000 ppm and ≥ 1 Vol%) by LED. Concentration-dependent increasing intermittent acoustic signal tone (can be switched off); continuous tone ≥ LEL 4 Vol% H2 (cannot be switched off). Automatic zero setting on air after switch on. Suppression of background concentrations up to 250 ppm by SET-key.
