Fast Hydrogen Leak Detection to Find All Leaks
A leak can be microscopic, large, or even enormous. The challenge is that even when searching for small leaks, they can unexpectedly be large, and your leak detector must be capable of detecting them without saturating.
The need to find all leaks influences the choice of the perfect leak detector for each situation. With the renowned Sensistor Sentrac hydrogen leak detector, this choice is considerably simplified. Known for its high sensitivity, wide leak dynamic range, and short recovery times, the Sensistor Sentrac has proven to be a perfect instrument for leak detection in production and maintenance.
Detects a Wide Range of Leak Types
The Sensistor Sentrac is the perfect solution for industrial applications where rapid leak localization is crucial and where production flow leak testing should not be hindered by any single large-volume tracer gas leak. The instrument detects leaks from very small to enormous and is the ideal choice for testing products that must be fluid-tight.
With its Strix™ sensor, the Sentrac offers not only even faster response times but also much quicker recovery than its predecessor. This means you can now detect the smallest leaks more easily, without compromising your ability to detect the largest ones. It also means you will be prepared to detect a small leak immediately after detecting a large one.
Low Cost of Ownership
The Sensistor Sentrac uses a low-cost formation gas (5% hydrogen in nitrogen) as a tracer gas. Furthermore, thanks to the longer sensor life, absence of moving parts, and no maintenance requirement, the instrument reduces the total cost of ownership, making it an excellent option.
Key Advantages:
- ✔️ Higher performance in localization tasks
- ✔️ Reduces the risk of missing small leaks
- ✔️ Detects and supports the widest range of leak sizes
- ✔️ Battery-powered model for true portability
- ✔️ Truly intuitive search modes
- ✔️ Resistant to high tracer gas levels
- ✔️ More effective than aerosol soap
- ✔️ Longer sensor life
- ✔️ Low cost of ownership
