Sensistor® XRS9012 Hydrogen Leak Detector

The Sensistor XRS9012 Hydrogen Leak Detector is a fast, reliable and robust instrument for utilities leak detection such as telecom cables and water pipes. The Sensistor XRS9012 offers a highly sensitive and flexible leak detection system in a heavy-duty, smart and ergonomically designed package.


The unique method involving the use of inexpensive forming gas (5% hydrogen and 95% nitrogen) as tracer gas, combines unparalleled locating properties with user-friendly technology, low costs and minimal service requirements.

To be able to detect both minor and major leaks the Sensistor XRS9012 features a sensitivity adjustor to instantly adapt to any detection condition. The electronic sensor mounted in the probe tip responds instantaneously to the tracer gas. The sensor is also highly sensitive and selective to hydrogen gas. Additionally, the instrument has a very short recovery time to enable new measurements to be performed immediately.
