Hydrogen Leak Detector – Sensistor Sentrac

INFICON

Ideal for finding small and big leaks
Detects a wide range of leak sizes
Fast reaction and recovery time for small leaks
Low cost of ownership
Intuitive interface with touch display

The Sensistor Sentrac Hydrogen Leak Detector is a high-performance hydrogen leak detection system designed to identify both small and large leaks with exceptional sensitivity and a wide dynamic leak range. It features the innovative Strix sensor, which enables faster reaction and recovery times, making it ideal for industrial applications where quick and accurate leak detection is crucial. The device is available in three models: desktop, portable, and panel, offering flexibility for various production environments. It uses forming gas (5% hydrogen in nitrogen) as a tracer gas and has a low cost of ownership due to its long sensor lifetime and minimal maintenance requirements. The system includes an intuitive interface with a large, bright full-color touch display and multiple modes (Locating, Measuring, and Combined Mode) for efficient leak detection. It also supports integration into automated systems through accessories like the R50 Robot Probe and AP29ECO Sampling Probe, enhancing its versatility in industrial settings.

Use Cases

Truly intuitive search modes

INFICON INFICON, a global supplier of leak detection and gas analysis solutions with decades of expertise identifying hydrogen gas at the lowest concentrations, provides advanced leak detection technology enabling both quality assurance of hydrogen production systems and components as well as real-time hydrogen detection of even the smallest leaks, minimizing accident risk and ensuring production system integrity. The company's Sensistor Sentrac Hydrogen Leak Detector locates and quantifies a wide range of leaks faster and more accurately than soap spray or helium leak detection methods, serving critical applications across hydrogen electrolyzer stacks (where numerous cells with membranes, electrodes, and seals must be monitored to prevent dangerous leaks), compressed hydrogen storage (regularly inspecting compressor housings, seals, and pistons), and piping/gas manifolds where hydrogen's tiny molecular size can escape through the smallest holes in fittings, joints, and valves. INFICON's Strix hand probe, introduced for automotive applications including engine assemblies, air-conditioning systems, battery cases, brake lines, and fuel systems, is 30% lighter and 12.5% smaller-tipped than previous handheld probes, using complex algorithms to shorten measurement times, improve accuracy, and speed recovery times when connected to the Sentrac Hydrogen Leak Detector with a non-flammable hydrogen-nitrogen tracer gas mixture. As hydrogen production and applications continue expanding globally, INFICON's comprehensive leak detection portfolio -- spanning production, transportation, and storage pathways -- supports the safe deployment of hydrogen infrastructure by identifying potential leak points before they develop into major hazards or resource losses.
