The High-Temperature Oxygen Index (TOI) measuring instrument determines oxygen index at up to 125°C, offering better flammability assessment than traditional methods. As gas temperature increases, the oxygen index decreases. It follows ISO 4589 Part 3 or NES 715 standards, achieving high temps via preheated gas and furnace wall settings. A built-in pump conserves gas between tests, with nitrogen and oxygen bottles connected only during testing.

Application

Evaluating material combustion performance in R&D.

Quality control for product acceptance.

High-temperature safety assessment in industries like aerospace, automotive, and construction.

Standards

ISO 4589-3: Plastics – Oxygen index method (high-temperature test).

GB/T 2406.2 / ISO 4589-2: Plastic oxygen index test (normal/high-temperature).

ASTM D2863: Plastic oxygen index standard.

GB/T 5454-1997: Textile oxygen index method.

NES 714/715: UK oxygen index test standards.

Product Advantages

High-Temperature Precision: Tests up to 200°C with rapid response (10s heating).

Accurate Oxygen Control: ±0.5% concentration accuracy (0–100% range).

User-Friendly Design: Full-color touchscreen with Chinese/English interfaces.

Versatile Testing: Suitable for diverse materials (plastics, rubber, textiles).

Safety Compliance: Meets global standards for reliable data.

Feature

Testing Principle: Vertical sample combustion in oxygen/nitrogen gas flow. Combustion time and oxygen percentage are measured to determine LOI.

Key Components

Heat-Resistant Cylinder: Borosilicate glass (inner dia. >75mm, height >550mm).

Stainless Steel Beads: Enhances gas flow uniformity (4mm dia., 80–100mm height).

Pilot Burner: 2mm inner dia., 400mm length for precise ignition.

Gas Control: Automated oxygen/nitrogen mixing with flow rate 12.1L/min.
