ISO 4589-3 High Temperature Limited Oxygen Index Tester AC220V

ISO 4589-3 High Temperature Oxygen Index Testing Equipment

Introduction:

The high temperature oxygen index tester is based on the ordinary intelligent oxygen index tester. An electric heating device is added to the combustion tube to preheat the mixed gas, and the ignition temperature of different materials under a certain oxygen concentration is tested. Combining PLC-driven precision and a 1000W heating system, it ensures compliance with ISO 4589-3 for plastics, films, and textiles. The system’s auto-calibration, real-time data tracking, and fail-safe mechanisms make it a top choice for high-throughput labs and industrial quality assurance teams.

Applications:

• Certification testing for consumer electronics, automotive interiors, and fire-resistant textiles.

Features:

• Full Automation: Set desired oxygen levels via touchscreen; the system auto-adjusts gas flows and records results.

• High-Speed Testing: Measures ignition time with ±0.5s accuracy, reducing lab turnaround times.

• Versatile Compatibility: Tests materials ranging from rigid polymers to flexible films.

• Comprehensive Safety: Includes overload protection, emergency stop buttons, and gas leakage detectors.

• Equipped with an imported paramagnetic oxygen concentration sensor, with no service life limit.

• Equipped with a high temperature resistant quartz glass cylinder, outlet inner diameter 40mm, inner cylinder (inner diameter greater than 75mm, height greater than 450mm), outer cylinder (gap with inner cylinder between 5 mm~10 mm, height the same as inner cylinder).

• Equipped with a self-supporting sample specimen clamp and a non-self-supporting sample specimen clamp.

• Equipped with nitrogen and oxygen mass flow controllers imported from Japan, accurately control gas flow, accuracy of 0.01L/min (different from float flowmeters that require manual adjustment of oxygen and nitrogen flow).

• Patented gas flow mixing control unit, equipped with nitrogen and oxygen mass flow controllers, accurately controls gas flow.

• After the screen sets the oxygen concentration, the PLC LCD touch screen control system automatically adjusts the oxygen concentration according to the set value. Accurate control and convenient.

• Patented gas mixing chamber ensures more accurate oxygen concentration measurement and more complete mixing of oxygen and nitrogen;
