Brief introduction: Thermal protection index tester is suitable for the textile and apparel, petroleum chemical industry, labor safety and quality supervision, inspection and other industries and institutions for protective clothing, the requirement of the thermal performance test for the development of flame retardant protective clothing, in the process of production quality control and flame retardant protective clothing for use in thermal performance test to provide scientific and reliable basis. To detect protective clothing, safety shoes, gloves, helmet surface such as thermal protection performance. Through the established under the action of thermal radiation heat source, thermal protection performance of test materials. Standard: NFPA 1971, ASTM D4018, GB 8965.1 2009 Features: 1. The thermal protective device of the basic components: sample fixture components, spray rotor radiation heat source, water-cooled shutter sensor, data acquisition system, fuel control regulator, gas rotary flowmeter; 2. Heat source: 1 set of convection heat radiation heat source and two 45 °. Radiation heat source is composed of 9 T - 150 infrared quartz tubes. Convection heat source is made up of two beautiful gram lights. 3. Portable stainless steel protection plate 4.2 45 degrees Meker burner 5. The pipe diameter is 38 mm, inner hole diameter of 5/16 of an inch, 800-1200, BUT the heat output, burner for metal mesh structure, adjustable burner under the nerazzurri valve, air and fuel gas mixture ratio can be adjusted 6.9 T150 quartz infrared tube array, can provide thermal radiation flux for 13 kW/m2 + 4 kW/m2 7. Under the quartz tube infrared thermal radiation, by adjusting the supply Meker gas burner, the total heat flux can be set to 83 kW/m2 + 2 kW/m2 8. The calibration of heat flow meter for water-cooled type, working range of 0-80 kw/m2, maximum range is 150% 9. Heat flow meter response time is less than 200 ms, radiation rate is greater than 0.95, the work within the scope of the output signal is greater than 5 mv 10. Equipped with thermal radiation flux display instrument, can even show heat flux values 11. Inspection of protective material coefficient of thermal protection TPP, display time - temperature curve
