Easy to use high performance leak testing
Fast, easy to use, and durable. Hydrogen Leak Detector H2000 PLUS - a breakthrough in leak detection and tightness control.
Searching for leaks using hydrogen, called the Hydrogen Method, is today an established method in the industry. Sensistor launched its first leak detection and tightness control system, based on the hydrogen gas method, more than 20 years ago. Many different types of industry all over the world use this method today. The reason is that hydrogen as a tracer gas has several advantages compared to helium, for example. And now there will be even more advantages. Sensistor has developed a new generation of leak detectors that add new advantages and qualities to the Hydrogen Method.
Unique and reliable
The hydrogen leak detector H2000 PLUS is a unique instrument for industrial leak detection and tightness control. It is small, robust, and extremely sensitive to hydrogen gas. It can be used to detect leaks as small as 5x10-7mbarl/s. It is also insensitive to other gases and has a unique capability of handling background levels of hydrogen gas. In other words, everything required for sensitive and reliable testing.
The optimal tracer gas
Leak detection using the hydrogen method is becoming more common in industry. One reason for this is that hydrogen is the cheapest tracer gas available. The actual gas mix used is a safe mixture of 5% hydrogen in nitrogen. Another reason is the inherent characteristics of hydrogen. Hydrogen is the lightest and least viscous of all gases. It spreads very quickly throughout the test object and seeps quickly through the smallest leak. Background interference is easily minimized because of the speed with which hydrogen dissipates. The method requires no pumps or vacuum and thus needs a minimum of maintenance.
Gives more possibilities
When using the hydrogen method and the H2000 PLUS, leak detection is no longer a choice between a water bath, pressure testing, and a mass spectrometer. Now you can customise your solution to suit your requirements and budget. Hydrogen gas detection with the H2000 PLUS offers flexible solutions that have not previously been available. For example, you can measure pressure drop in order to disclose leaks and localise them with hydrogen gas. Or you can use hydrogen gas and the H2000 PLUS to detect leaks with high sensitivity, independent of temperature. A modern method Leak testing using gas is used when it is unsuitable to put the test object in a water bath, when pressure decay cannot be used because of temperature interference or when the test object is elastic. Taking the step from water bath to leak detection with a tracer gas is considered to be a major one, both as regards price and complexity. But with the Hydrogen Method and the H2000 PLUS, the step to modern and efficient leak testing is much smaller.
With the H2000 PLUS you minimise problems with background interference, because hydrogen gas is dissipated much quicker than other gases like helium and because the H2000 PLUS has dynamic background compensation.
H2000 PLUS is entirely electronic. No pumps, valves, or other things that require maintenance. No service is thus needed. If the probe is damaged, the operator himself can replace it in just a couple of minutes.
H2000 PLUS is small and robust. It is easy to move around when searching for leaks on a large object, e.g. an aircraft. It can also be easily transported in a suitcase when travelling, e.g. for a service engineer.
H2000 PLUS is very easy to use. Switch on the power and wait just one minute. Then start searching for leaks. If the standard settings are unsuitable, change them simply by browsing through the menus on the display.
H2000 PLUS is suitable for leak detection in tough factory environments. The standard H50 probe has no sample suction and can thus be used without worrying about dust. The probe can be equipped with a protective cover that allows leak detection on wet objects.
H2000 PLUS is based on modern digital technology and does not require trimming or calibration other than by simply pushing buttons. It can be calibrated with a reference gas or a reference leak.
Facts about the tracer gas
Pure hydrogen is never used as a tracer gas because it is highly inflammable. A gas mixture comprising 5% Hydrogen gas and 95% Nitrogen gas is used instead. This gas mixture is not inflammable (see ISO 10156) and is not toxic or corrosive, nor dangerous to the environment. Both hydrogen gas and nitrogen gas are present in all biological systems. Some gas suppliers have their own trade name for this gas mixture.
