LFY-608 Convection Heat Conduction Tester

Main application

The convective heat resistance tester is used to evaluate the convective heat resistance performance of protective gloves, protective clothing, and heat-resistant clothing. The test result is the heat transfer index (HTI). The testing principle involves applying a flame impact to the bottom of the sample and measuring the time required for the temperature on the back of the sample to rise by 12°C or 24°C. The average value of the test is recorded as the heat transfer index (HTI), which is used to assess the thermal protection performance of protective clothing fabrics.
