Testing Applications
This glow wire tester is essential for evaluating fire hazards in electrical and electronic products including lighting equipment, household appliances, electric tools, information technology devices, and various insulation materials and engineering plastics.
Safety Features
- Over-temperature and low-temperature protection with automatic heating control
- Automatic heating shutdown after 5 minutes of operation
- Comprehensive safety protocols for electrical shock, scalding, and fire prevention
- Exhaust fan system for toxic gas and smoke management
Working Principle
The system heats a nickel-chromium U-shaped glow wire to specified temperatures using high current, then applies pressure to test specimens for 30 seconds. Results determine ignition risks based on material burning characteristics, flame duration, and flammability indices.
Important Safety Notice
Always follow safety protocols to prevent electrical shock, scalding, burns, or fire accidents. Ensure proper ventilation to avoid inhalation of toxic gases or smoke, and handle test residues with appropriate protective equipment.
