Sensistor® ISH2000
Hydrogen Leak
Detector
Ideal for Finding Big and Small Leaks

Fast and Cost Effective
Industrial Leak Detection
The Sensistor ISH2000 is a robust
instrument for professional leakdetection, both manual and automatic.
The unique method involving theuse of inexpensive forming gas (5 %hydrogen and 95 % nitrogen) as tracer
gas combines unmatched measuring
properties with user-friendly technology,
low costs and minimal service
requirements.
This makes the Sensistor ISH2000 the best
option for a wide range of production andmaintenance applications. It is especiallysuitable for finding leaks of a size thatwould leak liquids such as water, fuel andoils or in environments with occasionallarge leaks.
With its unique tolerance to high gas
concentrations, the Sensistor ISH2000
is superior in precisely pinpointing leaklocation, irrespective of leak size.

A PPLI CAT I O N S
The optimal system solution for avariety of demanding applications:n Automotiven Refrigeration and Air Conditioning (RAC)nAerospacenPackagingn Manufacturing industry, e.g. pipes,valves, couplings, hoses, containersSENSISTOR SENSORT E C H N O L O GYSensistor ISH2000 incorporates the provenSensistor Sensor Technology developedfor using forming gas (5% hydrogen innitrogen) as tracer gas. This hydrogengas sensor, which relies on diffusion, isextremely sensitive and selective. It isplaced in the probe tip and can be easily
water protected to allow for leak locating
on wet objects. Sensor replacement isperformed easily within seconds.

A DVA N TAG E S AT A G L A N C E■ Smart accessories adapt the detector to a wide range oftesting situations - from manual sniffing to fully automaticchamber testing■ Low maintenance thanks to no moving parts■  High sensitivity combined with excellent performance inhigh concentrations, makes it easy to locate leaks■ Short recovery time reduces downtime when detecting
gross leaks■  Easy sensor fitting allows the operator to replace thesensor in a matter of seconds

The ISH2000P is designed for panel mounting,perfect for automatic leak testing.

FACILITATE FOR THE OPERATOR■ High sensitivity – detects smaller leaks
and shortens the time for each test cycle■ Combined screen display for “Measure”
and “Locate” improves the efficiency ofthe operator’s work■ Alternative alarms through different types
of audio signals and/or visual indicators on
the screen■ The audio alarm can be clearly heard
even in noisy environments, and in cases
where the measurement point and theinstrument are far apart■ Adjustable audio indication makes themeasurement procedure easier. Choose
between continuous audio signal, audio
signal only at alarm level, or audio signal ata defined percentage of the alarm level■ A choice between pre-definedmeasurement units for leak flow, PLUS
programmable unit, supports the setting upof the instrument for different measurement
situations■  Multi-point measurement withaccumulation of the values makes it
possible to add several leaks and comparewith the total threshold value

ERGONOMIC HAND PROBE WITH BUILT-IN INTELLIGENCE■  Easy sensor fitting makes it simple to replace the sensor in a matterof seconds■ Short recovery time reduces downtime when detecting gross leaks■ Built-in illumination source of the probe helps precisely position theprobe tip■ LED Leak indication in the hand probe provides the operator withfast information during the leak detection process■ Automatic Zero setting eliminates problems with high backgroundlevels of tracer gas

PROBE CABLES■  Probe cables in lengths of 3, 6 and 9meters (9.8, 19.6 and 29.5 ft.) for a varietyof test situations■ Robust, for use in tough industrial
environments
