Trace400 Portable helium detector

The Trace400 helium leak detector is a state-of-the-art helium detector, using the proprietary and patented Selective Ion Pump Detection (SIPD) method. The Trace400 SIPD sensor incorporates a quartz capillary tube maintained under high vacuum by an ion pump. The quartz tube is heated with a platinum filament and becomes permeable to helium. As the partial pressure of helium in the ion pump increases, so does the current drawn by the ion pump (proportional to the pressure).

The onboard processor converts the current draw to the corresponding helium concentration present in the Trace400 test probe.

The Trace400 helium leak detector weighs only 2,6 Kg (5.7 lbs), including the battery. Its compact size allows it to be easily carried anywhere and the ergonomic design allows comfortable use for extended periods of time.
Since the Trace400 helium leak detector is capable of detecting both very small and large leaks, an automatic backflow valve prevents helium saturation. This ensures fast response times as well as a longer life for the sensing element.
