AMZ-Warehouse RT100S Big Blu Micro Leak Detector 1 qt (Viper) — NSF-certified, non-corrosive, low-evaporation

This leak detector fluid from AMZ-Warehouse combines sensitivity, material compatibility, and food-safe certification so technicians and facility managers can find micro leaks quickly without risking corrosion or contamination. Formulated for refrigeration systems, it spreads evenly, clings to joints and fittings, and produces visible bubbles at leak points to reveal hairline escapes that typical bubble solutions miss.

How precise is this detector for tiny refrigeration leaks?

The RT100S Big Blu detects extremely small losses — as little as 0.65 ounces per year — making it suitable for spotting hairline defects and slow seepages that can cause efficiency loss over time. Its low-foaming formula highlights leak sites without evaporating quickly, so technicians get reliable visual confirmation.

• Detects micro leaks down to 0.65 oz/year
• Visible bubbling at pressurized joints and fittings
• Low-evaporation, extended dwell time for inspection

Is it safe to use on refrigeration lines and near food?

Yes — the RT100S Big Blu is NSF certified for use around food environments and is formulated to be non-corrosive to metals and seals commonly used in refrigeration systems. That reduces the risk of damage to copper, aluminum, brass, and rubber components during routine inspections.

• NSF certification for food-contact area safety
• Non-corrosive to common refrigeration metals and seals
• Compatible with a range of system gases and lubricants

Which gases and systems can this detector be used with?

The product is designed to be safe on any type of gas used in refrigeration and air conditioning systems, so it can be used across residential, commercial, and industrial applications. Its broad compatibility eliminates the need for multiple detector fluids for different refrigerants.

• Safe for all refrigerant types
• Suitable for HVAC, commercial refrigeration, and transport units
• Works on pressurized lines, valves, fittings, and brazed joints

How do technicians apply and interpret results quickly?

Application is straightforward: apply the fluid to the suspect area and watch for steady bubbling that indicates escaping gas. Because the formula produces long-lasting, easy-to-see bubbles, techs can confirm leaks without repeated applications or complex equipment.

• Apply with brush, spray, or dropper to suspect areas
• Look for continuous bubbles forming at leak points
• Minimal reapplication needed due to cling and low evaporation

Who is this for: The RT100S Big Blu Micro Leak Detector is ideal for refrigeration and HVAC technicians, facilities maintenance teams, grocery and foodservice operators, and transport refrigeration specialists who need a dependable, food-safe detection fluid. It suits professionals who require high sensitivity for preventative maintenance, warranty diagnostics, or compliance checks — anyone who must find and verify tiny leaks quickly while protecting system components and food environments.
