Herth+buss leak detector selecth2 leak detector select h2 h b

Selective gas leak detector for air conditioning and refrigeration systems, gooseneck length 320 mm, aluminum housing, equipped with a suction pump and two sensors that draw in the test medium. Leak detection is carried out using forming gas 95/5 (95% nitrogen, 5% hydrogen, also used as a shielding gas in welding and can usually be obtained without problems from any gas specialist retailer). Defective heat exchangers can be detected even without removing the dashboard. The device only reacts to the hydrogen contained in the forming gas and thus excludes misdiagnoses due to oil and petrol vapours. Also suitable for large truck and bus air conditioning systems. With automatic zero point calibration with fresh air, switchable concentration-dependent signal, automatic sensor check with fault detection and high-quality NiMH batteries without memory effect. Fully complies with Directive 2006/40/EC on emissions from air conditioning systems in motor vehicles. Scope of delivery: Delivery includes mains charger in a plastic case with lid padding and gas-free insert (important for storage). To ensure the high precision of the device in the long term, annual calibration by the manufacturer is recommended.
