Autoignition Temperature Tester DF-6500
DINTOK DF-6500 Autoignition Temperature Tester conforms to ASTM E659 Standard Test Method for Autoignition Temperature of Chemicals. A small, metered sample of the product to be tested is inserted into a uniformly heated 500ml glass flask containing air at a predetermined temperature. The contents of the flask are observe in a dark room for 10min following insertion of the sample, or until autoignition occurs. Autoignition is evidenced by the sudden appearance of a flame inside the flask and by a sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which hot-flame ignition occurs for a series of prescribed sample volumes is taken to be the hot-flame autoignition temperature of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) are measured in order to determine the ignition delay-ignition temperature relationship.

Precise Determination of Autoignition Hazards with the Autoignition Temperature Tester DF-6500
Ensure safety and regulatory compliance in chemical handling, storage, and transportation with the Autoignition Temperature Tester DF-6500—a high-precision, automated instrument engineered to determine the autoignition temperature (AIT) of liquids, gases, and vapors in accordance with ASTM E659, IEC 60079-4, EN 14040, and GOST 12.1.044. Critical for petrochemical, pharmaceutical, and industrial safety labs the DF-6500 identifies the lowest temperature at which a substance spontaneously ignites in air—without an ignition source—providing essential data for hazard classification and process design.
Engineered for Accuracy, Safety, and Regulatory Confidence
The DF-6500 Autoignition Temperature Tester features a high-temperature glass or metal test chamber (up to 800°C) with precise PID-controlled heating, an automated sample injection system, and high-sensitivity optical or thermal ignition detection. A small sample is injected into the preheated chamber, and the instrument records the temperature at which spontaneous combustion occurs. The system includes forced-air cooling for rapid cooldown between tests and explosion-resistant shielding for operator protection.
- Compliant with ASTM E659 & IEC 60079-4 – Validated for safety data sheets (SDS), ATEX, and OSHA compliance.
- Temperature Range: Ambient to 800°C – Covers most organic solvents, fuels, and industrial chemicals.
- Automatic Sample Injection & Ignition Detection – Eliminates manual error; ensures repeatable results.
- Dual-Chamber Option (Optional) – Enables testing in air or inert atmosphere for comparative analysis.
- Safety-First Design – Explosion-proof window, fume exhaust, overheat protection, and emergency stop.
- Data Logging & Reporting – Stores test parameters, AIT results, and video capture (optional); exports to PDF/CSV.
