Burning wire tester for testing the ignition (temperature) of combustible materials

Scope of application:

ZNZRS-2scorchingThe ignition (temperature) test of combustible materials using a silk tester is used to determine the ignition, ignition temperature (GWIT), flammability, and flammability index (GWFI) of solid insulation materials and other solid combustible materials. It is also suitable for industries such as insulation materials, engineering plastics, or other solid combustible materials.

Touchscreen hot wire tester (white box is also available according to customer needs, and non-standard customization of 0.75m ³ or 1m ³ box is also possible. The box material can be customized with stainless steel material)

The hot wire tester heats a specified material (Ni80/Cr20) and shape of electric heating wire (Φ 4 mm nickel chromium wire) with high current to the test temperature (550 ℃~960 ℃ for 1mi), and then vertically burns the test sample at the specified pressure (0.95 ± 0.1N) for 30 seconds. The ignition hazard of the finished electrical and electronic equipment is determined based on whether the test sample and the substrate ignite or hold on for a certain period of time;

Burning wire tester for testing the ignition (temperature) of combustible materialsFunctional features:

1. Adopting a single-chip microcomputer and touch screen control, a high-precision temperature gauge independent electronic control system solves the problem of the PLC system's inability to achieve actual digital to analog conversion accuracy while improving anti-interference ability. Adopting microcomputer control is more precise.

2. Start, timing, exhaust, lighting, and heating are all implemented on the touch screen; After the completion of a set of experiments, the device automatically pops up the save button, and only the save name needs to be edited; All saved data can be queried in historical data

3. seven inchescolorfultouch screen

4. Intelligent 7mm limit adjustment

5. Fixture adapts to various shapes and sizes of specimens

6. X. Z-direction free movement, convenient for customers to locate samples

7. Adopting one click operation, the entire testing process is completed with one button during the experiment, without the need to switch between complex buttons

8. The sample car adopts a fully enclosed structure and will not overturn

9. Equipped with a flame height gauge for easy observation of flame height

10. overtemperature protection
