The autoignition temperature refers to the lowest temperature at which an oil sample ignites spontaneously in air without an external ignition source. This parameter is an important safety indicator for fire-resistant oils used in power generation systems, especially in turbine control systems and hydraulic systems where fire safety is critical.

The Autoignition Temperature Tester heats the oil sample in a standard flask under controlled temperature conditions until spontaneous ignition occurs. By accurately controlling the temperature rise and monitoring the ignition behavior, the instrument determines the minimum temperature at which combustion occurs.

The tester features high-precision intelligent temperature control and uniform heating, ensuring accurate and reliable measurement results. A three-point temperature monitoring system measures the temperature at the bottom center, middle sidewall, and upper part of the flask, ensuring minimal temperature difference and high measurement accuracy.

This instrument is widely used in power plants, petroleum laboratories, hydraulic fluid testing laboratories, and research institutions.

The Autoignition Temperature Tester is used to determine the autoignition temperature of fire-resistant oils and industrial lubricants.

• Fire-resistant hydraulic oils
• Turbine control oils
• Phosphate ester hydraulic fluids
• Industrial lubricating oils
• Operating oils used in power plants

Typical application environments include:

• Power generation plants
• Electrical utilities
• Petroleum and lubricant laboratories
• Hydraulic fluid manufacturers
• Research and testing institutes

The instrument adopts an intelligent temperature control system with uniform heating to ensure stable and accurate test conditions.

The tester measures temperature simultaneously at three positions (bottom center, middle sidewall, and upper section) of the flask, ensuring temperature uniformity with minimal deviation.

The system supports testing temperatures from room temperature up to 800°C, covering a wide range of oil autoignition tests.

The temperature difference between the three measuring points is controlled within ≤1°C, ensuring reliable test results.

The instrument structure is optimized for safe operation in high-temperature testing environments.

This Autoignition Temperature Tester is designed according to:

• DL/T 706 – Test Method for Autoignition Temperature of Fire-Resistant Fluids Used in Power Plants
• ASTM E659 – Standard Test Method for Autoignition Temperature of Liquid Chemicals
• ISO 20823 – Determination of the Autoignition Temperature of Liquid and Solid Materials

These standards are commonly used for evaluating the spontaneous ignition characteristics of liquids and industrial fluids.
