HY4820 Glow Wire Tester uses the specified material Ni/Cr(80/120) and shaped wire to test the temperature (550℃~960℃) via large current within 1 minute, and vertically presses the specimen with a specified pressure (1.0N) for 30 seconds. Then, observe whether the specimen is ignited or the burning time to determine the fire risk of electrical products, insulation materials, etc. This instrument complies with the following international and industry standards: DIN: DIN 695; UL: UL 746A. It adopts a digital instrument control system and imported control components. The fixture is made of high-quality stainless steel, which is corrosion-resistant and rust-free. It is equipped with a one-button timing device for easy equipment use and simple operation. The advanced temperature control and temperature measurement system makes the test more accurate and the results more reliable. The tempered glass observation window allows observation of the entire test process.
