In industrial gas systems, even micro-leaks can lead to catastrophic failures—safety hazards, regulatory fines, and costly downtime. Traditional detection methods (electronic sensors, soap solutions) often miss these risks due to:
Result: Companies face unplanned shutdowns (avg. $100K/day in lost production), safety incidents, and non-compliance penalties.
⚠️ Industry Alert: The IEA’s 2025 Global Hydrogen Review reports that 40% of hydrogen leaks in industrial systems are undetected by conventional methods, contributing to $2B+ in annual losses.
Our solution? Bubble leak detectors with military-grade precision—no false alarms, no missed leaks.
While electronic methods dominate marketing, bubble leak testing remains the gold standard for:

|---|---|---|---|
| Detection Sensitivity | ≤0.01 cc/min (Class 1 per ASTM E1003) | ≤0.1 cc/min (Class 2) | ≤0.5 cc/min (Class 3) |
| Gas Compatibility | All gases (H₂, He, CH₄, SF6, etc.) | Limited ( Conductive gases only) | All gases |
| Environmental Resistance | IP67 (Dust/Waterproof) | IP54 (Dust-resistant) | None |
| Calibration Frequency | None | Weekly | N/A |
| Cost (Per Unit) | $200–$1,200 | $5,000–$50,000 | $50–$200 |

On-site leak detection at a Saudi Aramco hydrogen facility using BL-200H.
A bubble leak detector applies a test fluid (soapy solution) to a pressurized system. If there’s a leak, bubbles form at the leak site, providing visual confirmation of the location and size. Our detectors use high-sensitivity fluids that create stable, long-lasting bubbles even in windy or humid conditions.
Our detectors work with all gases, including:
Our standard models detect leaks as small as 0.01 cc/min (Class 1 per ASTM E1003). For specialized applications:
For comparison, human hair is ~0.05 mm thick—our detectors can find leaks 10x smaller than that.
Yes! Our detectors are built for harsh conditions:
Example: Our BL-200H is used in Arctic LNG projects where temperatures drop below -50°C.
