1. Product Overview
The A2L refrigerant hot surface ignition temperature tester determines the lowest temperature at which A2L refrigerant can be ignited by a high-temperature hot surface under specific conditions; this is known as the hot surface auto-ignition temperature. This data is crucial for assessing the potential fire risk when refrigerant leaks and encounters hot surfaces such as electrical components or overheated pipes.
