Glow Wire TesterTechnical Specifications:

Hot wire test chamberUsed for electronic and electrical components or parts that may reach excessively high temperatures or ignite nearby parts under fault or overload conditions, the hot wire test simulates the thermal stress caused by heat sources or ignition sources such as hot elements or overloaded resistors in a short period of time, and evaluates the fire hazard using simulation technology. The hot wire tester is suitable for plastic and non-metallic insulation material parts used in electrical and electronic products, components, and household appliance components, such as switch housings, relay sockets, etc.

Glow Wire TesterBasic specifications:

1. Internal volume of the box: ≥0.5cubic meter, with a glass observation door
2. Illuminance inside the box: less than20LUX
3. Heating wire temperature: room temperature~ 1000℃ Adjustable,
4. Thermocouple: Temperature measurement adoptsØ0.5mmNickel chromium armor( Ktype)Imported thermocouple
5. Temperature allowable error:500 ~ 750℃±5℃；750 ~ 960℃±10℃
6. The force applied by the heating wire to the sample:1.0 ±0.2NAnd limit the depth of compression to7mm±0.5mm
7. Heating wire: Heating wire is made with a diameter of4mmThe nickel/Chromium（80/20）A standard size ring made of silk; The diameter of the heating wire before bending is4.0 +/- 0.04mmAfter bending, it must not be lowered to90%All other dimensions are made according to the error requirements of the standard;
8. The moving speed of the top of the heating wire approaching and leaving the sample ：10mm / s - 25mm / s；
9. Timer:0 ~ 99part 99 Adjustable within seconds, accuracy: ±1 Second scorching time(Ta)Can be set, ignition duration(Ti)And the extinguishing time of the flame(Te)recordable
10. Product features: The control system of this testing instrument is automated. After starting, the small car that holds the sample will automatically move the sample to the hot wire. After reaching the set hot time, it will automatically return. The interior has a black background and is equipped with ventilation and lighting devices. The time and temperature are displayed digitally for easy observation and recording.
