Convective Heat Resistance Tester
The instrument is used to determine the thermal resistance of protective clothing materials or samples and protective equipment by exposing the sample in the test condition of hot air circulation oven.
The metal frame of this instrument is equipped with rock wool thermal insulation layer. The door is used to enter the air circulation oven. The size of the door window is 460x580mm, made of a double-layer 4mm heat treatment and transparent glass. The oven operation temperature is as high as 300 ℃ , and the test automatically operates at (185 + / - 5℃) or (260 + 5℃). The fan air velocity is 0.5 m/s to 1.5 m/s. The thermocouple is located in accordance with the requirements of standard. The switch on the door is used to stop or start the hot air circulation for test running. Display failure and the achieved temperature. The voice signal of timer prompts the test time. The system can fix and suspend samples. The power of internal lamp is 2 x25w. The on/off switch can be used to control the equipment, interior lights and the mobile platform with clamps.
