Thermal protection performance tester

Thermal protection performance tester is used to detect the thermal protective performance of protective clothing, safety shoes, gloves, helmet exterior surface, and to detect the thermal protection performance of materials under the action of established heat radiation source.The sample is exposed to a heat source with the specified heat radiation energy, and the sensor signal is collected at high speed. The TPP value is calculated by the software, and the report is provided in the form of Excel or Word.
