Sensistor® Sentrac Hydrogen Leak Detector

The Sensistor Sentrac Hydrogen Leak Detector is a modern leak detector for industrial use. Based on the highly selective and sensitive Sensistor sensor, the instrument offers leak locating in a variety of situations both on the production and repair lines. Thanks to its unique ability to handle small and large leaks as well as high background levels of tracer gas, this leak detector is highly adaptable.


The leak detector’s hand probe is designed for maximum ergonomics and efficiency. The unit is controlled by a multi-function button for fast access to frequently used functions. It is equipped with LED lamps illuminating the area tested for leaks for more reliable pinpointing. The probe is also equipped with an easy-to-read OLED display to provide information about the entire leak detection process directly in the palm of your hand.

For added flexibility, the Sensistor Sentrac leak detector is available in both desktop and battery operated models.
