The Big Blu Subzero Micro Leak Detector (RT150S) is a professional-grade solution designed for HVAC, plumbing, and industrial technicians who require reliable leak detection in extreme environments. Its standout feature is its ability to remain fluid and effective in temperatures as low as -30°F, ensuring performance where standard detectors freeze or fail. While it provides industry-leading sensitivity for identifying minute leaks, users should note that the diagnostic process requires a 5-to-30-minute waiting period for the clearest bubble formation.

Yes, it is specifically engineered to be safe and effective for use with pressurized oxygen systems.
Yes, the product is NSF-certified, making it safe for use around food handling and preparation areas.
It can identify micro-leaks as small as 0.79 ounces per year.
No, the formulation is non-corrosive and safe for use on standard metallic piping components.
It works perfectly well in normal temperatures; the Subzero formulation is simply designed to perform in extreme cold where other products would fail.
Wait the full 30 minutes; micro-leaks take longer to manifest as foam than larger, high-pressure leaks.
The product is designed for -30°F; if it appears frozen, verify the ambient temperature and ensure the container was not exposed to temperatures lower than the specified limit.
Clean the connection point with a wire brush or clean cloth before applying the liquid to ensure the foam can form clearly.
This product requires no dilution or special setup; it is ready to use directly from the 1-quart container. Before application, ensure the surface area is free of excessive debris or heavy oil buildup to allow the solution to contact the metal directly. The product is chemically stable, but it should be stored at room temperature when not in use to maintain its peak shelf life. After the inspection, it is recommended to wipe the tested area with a dry cloth to prevent the accumulation of foam residue, which can attract dust over time. The solution is compatible with all common piping materials, including copper, steel, and industrial plastics.
