High Temperature Oxygen Index Tester

Product Overview

The High Temperature Oxygen Index Tester is an advanced combustion testing instrument designed to determine the minimum oxygen concentration required to sustain flame propagation in materials under elevated temperature conditions. It evaluates thermal stability and flame retardancy properties, critical for aerospace, automotive, and industrial material development.

Type: High-temperature oxygen index (OI) analyzer

Test Method: ASTM D2863 (Oxygen Index) with elevated temperature capability

Temperature Range: Ambient +20°C to 400°C (±1°C accuracy)
 

Key Metrics:

Oxygen Index (OI) at 23°C and elevated temperatures

Flame Spread Rate (cm/s)

Time-to-Ignition (TTI, seconds)

Sample Size: 100×100×3mm (adjustable clamping)
