A2L Refrigerant Hot Surface Ignition Temperature Tester
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 critical measurement, known as the hot surface auto-ignition temperature, is essential for evaluating fire risks when refrigerant leaks encounter hot surfaces like electrical components or overheated pipes.
