This manual provides user information for installing and operating the Sensistor ISH2000 HySpeed unit. For start-up installation advice please contact the supplier. The Sensistor ISH2000 HySpeed is a development of the ISH2000 range of hydrogen leak detectors adapted for rapid automated leak detection in packaging lines. The leak detection process is built on the Sensistor technology that uses diluted hydrogen as tracer gas.

Reference section The Getting started part consists of step by step case examples, explaining how to use the Sensistor ISH2000 HySpeed 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.
Description of equipment Sensistor ISH2000 HySpeed Sensistor ISH2000 HySpeed is a leak test detector optimized for high speed leak testing. The model is particularly aimed at testing packages, but possible to use for other applications as well where the time allowed for a LEAK/NO LEAK decision is extremely limited.

Hydrogen leak detector Sensistor ISH2000 HySpeed 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 HySpeed 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.
Gas sensor Technology The Sensistor ISH2000 HySpeed 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.

Hydrogen leak detector Sensistor ISH2000 HySpeed 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).
Hydrogen leak detector Sensistor ISH2000 HySpeed Operating Instructions Hint: It is good practice to detect a leak, locate it, and immediately remove the probe to avoid saturation. The probe is not damaged by the exposure but it will recover more slowly.
Hydrogen leak detector Sensistor ISH2000 HySpeed Operating Instructions Calibrate the leak detector Introduction The leak detector is the instrument and the probe together. This section of the user manual consists of step by step examples about how to calibrate the detector in the most common cases. For more about the calibration routine see the reference section.
