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, a digital display 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.

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.

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.
