Instrument Description:

This test instrument is mainly used for electronic and electrical components or parts that may reach excessively high temperatures or ignite nearby parts under fault or overload conditions. The glow wire test simulates the thermal stress caused by heat sources or ignition sources such as glow components or overloaded resistors in a short period of time. The simulation technology is used to assess the fire hazard, and is suitable for electrical and electronic products, components Plastic and non-metallic insulation materials used in household electrical components, such as switch housings, relay sockets, etc.

Product specifications:

1. Volume inside the box: ≥ 0.5 cubic meters, with glass observation door

2. Illumination inside the box: less than 20LUX

3. Glowing wire temperature: adjustable from room temperature to 1000 ℃,

4. Thermocouple: 0.5mm nickel chromium armored (K-type) imported thermocouple is used for temperature measurement

5. Temperature tolerance: 500~750 ℃ ± 5 ℃; 750~960 ℃± 10 ℃

6. The force exerted by the hot wire on the sample is 1.0 ± 0.2N, and the depth of pressing is limited to 7mm ± 0.5mm

7. Glow wire: Glow wire is a standard size ring made of nickel/chromium (80/20) wire with a diameter of 4mm; The diameter of the hot wire before bending is 4.0+/-0.04mm, and it should not be reduced to 90% after bending. Other dimensions are made according to the error requirements of the standard requirements;

8. The movement speed of the top of the hot wire approaching and leaving the sample: 10mm/s -25mm/s;

9. Timer: Adjustable within the range of 0~99 minutes and 99 seconds, with an accuracy of ± 1 second. The ignition time (Ta) can be set, and the ignition duration (Ti) and flame extinction time (Te) can be recorded

10. Product features: The control system of this tester is automated. After startup, the small car that clamps the sample will automatically run the sample to the hot wire. After reaching the set hot wire time, it will automatically return. The internal background is black, with ventilation and lighting devices, and time and temperature digital display for easy observation and recording.

11. Power supply: AC 220V, 50Hz
