This machine is used to test the change characteristics of wire and cable insulators or coated rubber test pieces before and after heating. It is suitable for wire, leather, plastic, rubber, cloth, before and after heating. In order to maintain the fresh air in the box when the wires are heated, the air exchange regulation is specially made. The testing machine is equipped with a precision designed air replacement adjustment device, digital voltmeter, ammeter, watt hour meter and timer, which can be used to measure the air replacement rate. The horizontal forced air circulation system and the air flow adjustment plates on both sides of the interior ensure that the internal temperature of the tester is uniform and stable. Comply to UL1581、ASTM-D2436、CNS3556、CNS742、JIS7212、JISB7757、ASTM 5423 and ASTM 5374.
