HERTH+BUSS Leak detector "SelectH2"

Selective gas detector for air conditioning and refrigeration systems, gooseneck: 320mm
Aluminium housing, the device is equipped with a suction pump and two sensors. The leak detection takes place by forming gas 95/5 (95% nitrogen, 5% hydrogen, is also used by gas shielded welding and can generally be obtained without difficulty via any gas trade). Defective heat exchangers can also be detected without dismantling the dashboard. The device responds only to the hydrogen contained in the forming gas and thus eliminates fault diagnosis by oil and gasoline fumes. Also suitable for large truck and bus air conditioning systems. With automatic zero calibration in fresh air, switchable concentration-dependent signal, automatic sensor check with fault detection and high quality NiMH batteries without memory effect. Complies fully with Directive 2006/40 / EC on emissions from air conditioning systems in motor vehicles.


Scope of delivery: mains charger in plastic case with lid padding and gas-free insert (important for the bearing). To ensure the high precision of the device in the long term, an annual calibration is recommended by the manufacturer.
