Refrigerant Leak Detectors
Detect halogenated refrigerants such as HFCs, CFCs, and HCFCs. Access hard-to-reach areas with the flexible probe. This unit can detect leaks as small as 0.1 oz. per year in air conditioning and refrigeration systems. An audible signal increases in intensity as you approach the leak.

Hydrofluorocarbons (HFCs), Chlorofluorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), R-22 (Freon) Refrigerant, R-134A Refrigerant, R-410A Refrigerant | 14" | Yes | Plastic Carrying Case | UL Recognized Component, CE Marked, SAE J2791, SAE J2913 | 0000000 | 0000000 |
Quick-Spot Compressed Gas Leak Detectors




Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs. These noncorrosive, nonflammable detectors find leaks in pipes, tubes, fittings, tanks, and cylinders. They wash off with water.
Detectors that are NSF registered P1 can be used in food-processing environments.

Quick-Spot Vacuum and Pressure Gas Leak Detectors

The aerosol can dispenses a foam that bubbles over pressure leaks and forms a crater over vacuum leaks, providing quick and reliable leak detection, while saving time and energy costs. This noncorrosive, nonflammable detector finds leaks in pipes, tubes, fittings, tanks, and cylinders. It washes off with water.

High-Visibility Quick-Spot Compressed Gas Leak Detectors
These detectors are fluorescent green. Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs. These noncorrosive, nonflammable detectors find leaks in pipes, tubes, fittings, tanks, and cylinders. They adhere to vertical surfaces. All wash off with water.
Use a UV flashlight for enhanced viewing.
Infrared Refrigerant Leak Detectors

Three times more sensitive than standard refrigerant detectors, these infrared detectors can identify leaks as small as 0.03 oz. per year. They have an easy-to-read LCD screen that displays the concentration of gas in parts per million (PPM). When a leak is detected, an indicator lights up and the device emits a sound. Check for leaks in hard-to-reach areas using the built-in flexible probe. Use them to detect a variety of halogenated refrigerants.
Product regulations restrict sales to the listed areas.
Add a sensor to detect carbon dioxide or flammable refrigerants.

Leak-Detecting Dye Kits for HVAC Systems


With bright-colored dye and a fully equipped kit, you have everything you need to spot leaks in your HVAC system. These kits come with the correct amount of dye required for your system's size. Inject the dye into your system and scan it with the UV light—the dye is fluorescent, so it’s easy to spot most leaks right away. For small leaks, let the dye circulate for 24 hours and then inspect it again. Use the dye cleaner before you fix a leak. If the repair isn’t sufficient, you’ll be able to spot more dye.
Kits with UV dye and sealant are formulated to seal hard-to-find leaks from the inside of your system. The dye and sealant formula is non-polymer and oil soluble, making it safe to stay in your system indefinitely. Reinforce seals from the outside for a permanent fix.
Kits that meet ANSI/ASHRAE adhere to standards for chemical stability.
Kits that meet SAE J2297 include dye that was originally made to detect leaks in automotive AC systems.
