What type of leak detector is acceptable for Type I systems?

When testing Type I (small appliance) systems, you must use a detector that is capable of sensing refrigerant vapor in the air. The only detectors considered acceptable are halogen (electronic) leak detectors or any other refrigerant detector that the EPA has approved for this use. These electronic detectors respond quickly to refrigerant vapors and provide reliable leak indication, which is why they are required for Type I systems. Soap bubble detectors or colorimetric detectors aren’t recognized as the official leak-test method for Type I systems, and infrared detectors aren’t universally accepted unless they’re specifically EPA-approved for refrigerant leaks. The option that includes “or other approved refrigerant detector” covers those devices that the EPA has officially approved for this purpose.
