  • Page 4 Dear customer, You have just bought an INFICON Hydrogen Leak Detector Sensistor ISH2000. The Sensistor ISH2000 is an extremely sensitive and selective detector for hydrogen gas (H It is especially designed for leak detection using Hydrogen Tracer Gas (Hydrogen diluted with Nitrogen down to a safe concentration) which is the most effective and economical tracer gas for leak testing.

  • Page 5: User Information

    Reference section The Getting started part consists of step by step case examples, explaining how to use the Sensistor ISH2000 in a variety common situations. The Reference section consists of in depth explanation and additional information, which completes the user manual with all relevant information.

  • Page 6: Description Of Equipment

    Hydrogen leak detector Sensistor ISH2000 Operating Instructions Description of equipment Sensistor ISH2000 can be purchased in one of three versions. A desktop model (Sensistor ISH2000), a battery operated model (Sensistor ISH2000C), and a panel mount model (Sensistor ISH2000P). Sensistor ISH2000 Sensistor ISH2000 is equipped with a number of powerful functions making it very easy to integrate in a semi or fully automatic test system.

  • Page 7: Sensistor Ish2000P

    The panel mount model, Sensistor ISH2000P, has identical features of the Sensistor ISH2000. The difference is that the Sensistor ISH2000 can be installed in the operator’s panel or any other flat surface. Also it operates on +24 VDC. Mounting brackets and a panel rubber seal are delivered with the detector.

    Hydrogen leak detector Sensistor ISH2000 Operating Instructions Pressure shocks might cause strong sounds which can cause impairment of hearing. Check that all relevant legislation and safety standards are complied with before putting Sensistor ISH2000 into service. Hydrogen Tracer Gas for leak detection When pure hydrogen gas is released in air its flammability range spans from 4% to 75% of hydrogen in air.

  • Page 14: Working Principle

    Operating Instructions Working principle Gas Sensor Technology The Sensistor ISH2000 leak detector is using an extremely sensitive hydrogen gas sensor based on a microelectronic field effect transistor (MOS-FET). The gas sensitivity appears when hydrogen absorbs into the sensor through a metal alloy (metal hydride) layer.

  • Page 15: Operating The Detector

    Hydrogen leak detector Sensistor ISH2000 Operating Instructions Operating the detector To Detect leaks If all you wish to do is to detect the presence of a leak, that is, find out whether there is a leak or not, then use the Detection Mode (or use the detection bar in Combined Mode).

  • Page 16: To Quantify Leaks

    CAUTION! • Do not open detector! Service of this equipment may only be carried out by ser- vice organisations authorised therefore by INFICON, Sweden. • If the detector gets outer damage it must be controlled and repaired by service organisation authorised by INFICON.

It is very important that all delays in gas exposure as well as reaction time of sensor are taken into consideration when setting the calibration time.
  • Page 24 There is always some hydrogen gas in the background. In fresh air this is as low as 0.5 ppm (parts per million). Sensistor ISH2000 actively adjusts itself to the background. This is done automatically at start-upand thereafter, it slowly adapts itself to slow variations in the background concentration.
