Fast Hydrogen Leak Detection for Finding All Leaks
A leak can be microscopic, large, or even huge. Even when searching for small leaks, they can be unexpectedly large, requiring a leak detector capable of handling them without saturation. The need to find all leaks impacts the choice of the perfect leak detector. The INFICON Sensistor Sentrac hydrogen leak detector simplifies this choice.
Known for its high sensitivity, wide dynamic leak range, and short recovery times, the Sensistor Sentrac is a proven instrument for leak detection in production and maintenance.

Detect a Wide Range of Leak Sizes
The Sensistor Sentrac is ideal for industrial applications requiring quick leak location and where leak testing must not be impeded by large tracer gas leaks. It detects leaks from very small to huge, making it perfect for testing products that must be leak-tight for fluids. The Strix™ sensor offers quicker reaction and recovery times compared to previous models, allowing for easier detection of smaller leaks without compromising the ability to find larger ones. It also ensures readiness for detecting a small leak immediately after a large one.
Low Cost of Ownership: The Sensistor Sentrac uses inexpensive forming gas (5% hydrogen in nitrogen) as a tracer gas. With a longer sensor lifetime, no moving parts, and no need for maintenance, the instrument significantly lowers the total cost of ownership.
