HERTH+BUSS ELPARTS 95980006 Leak Search Set, Air Conditioning

Selective hydrogen gas detector for effective and environmentally friendly leak detection in air- conditioning and cooling systems using forming gas. The SelectH2 is fitted with a suction pump and two sensors. These operate like an artificial nose and suck in the test gas. With the SelectH2 you have a time-saving and environmentally sustainable alternative solution, which can be used for testing even large HGV and bus air-conditioning systems economically. The forming gas 95/5 (95% nitrogen, 5% hydrogen) is also used as inert gas in welding and is generally readily available from any gas retailer. The leak detection method using forming gas also complies fully with directive 2006/40/EU on emissions from air- conditioning systems in motor vehicles. The manufacturer recommends annual calibration to guarantee the high precision of the device in the long term. • maximum hit rate even with the smallest leaks • recognise defective heat exchangers even without removing the dashboard • only reacts to hydrogen and therefore prevents misdiagnoses due to oil and petrol vapours • automatic zero-point calibration in fresh air • concentration-dependent signal • automatic sensor check with error detection • plastic case with cushioned lid and gas-free insert (important for storage)
