This test instrument is mainly used for electrical and electronic components or parts under fault or overload conditions, may reach too high temperature or ignite parts near them, glow wire test simulates hot elements or hot elements such as overload resistors or ignition sources caused the thermal stress in a short time.used to evaluate the fire hazard by analog technology. It is applicable to plastic and non-metal insulating materials such as switch housings , relay sockets for electrical and electronic products, components and household appliances.



The tester is automated in the control system. After starting, the trolley with the sample will automatically run the sample to the glow wire. After the set hot time, it will automatically return. The interior is black background with ventilation and lighting. Time,temperature digital displaying, easy to observe records.
