Flame Retardant Tester
Glow Wire Tester
Glow Wire Tester
I. scope of use
Glow wire tester would stipulate material (Ni80 / Cr20) and the shape of the heating wire (4 mm Φ nichrome wire) in large current heated to test temperature (550 ℃ ~ 960 ℃, after 1 mi to specified pressure (0.95 + / - 0.1 N) vertical burning hot try 30 s, inspect goods and bedding content whether light-off or the burning time to determine the fire risk of electrical and electronic equipment finished product;Determination of ignitability, ignitability temperature (GWIT), ignitability and ignitability index (GWFI) of solid insulation materials and other solid combustible materials is also applicable to the industries of insulation materials, engineering plastics or other solid combustible materials.
Ii. Product features
1. Adopt the single-chip microcomputer + touch screen control, high-precision thermometer independent electronic control system, to solve the problem that the actual conversion accuracy of PLC system cannot reach, and improve the anti-interference ability.Microcomputer control is more accurate.
2. Start, timing, exhaust, lighting and heating are all realized on the touch screen;After a group of experiments, the device will automatically pop out and save, just edit and save the name;All saved data can be queried in historical data
3. Seven-inch color touch screen
4. Intelligent 7mm limit adjustment
5. Fixture is suitable for various shapes and sizes of samples
6. Move freely in the X and Z directions to facilitate customers to conduct sample positioning
7. One-key operation is adopted to complete the entire test process with one key during the test process, and there is no need to switch between complicated buttons
8. The sample car adopts completely closed structure and will not roll over
9. Equipped with flame height ruler for easy observation of flame height
10. Overtemperature protection
