Email Annex

Executive standards: GB/T 8018, ASTM D525
This instrument is designed and manufactured in accordance with the GB/T 8018-2015 test method. It is suitable for measuring the oxidation stability of gasoline under accelerated oxidation conditions.

Advantages

Energy saving & operator safety – A well-designed thermal insulation system reduces energy consumption and prevents the risk of scalding the operator.
Precise control & high automation – The system offers excellent control accuracy and a high degree of automation.
Real-time monitoring – During the test, all system parameters and pressure curves from both oxygen bombs are displayed in real time on the computer interface for easy observation.
Reliable structure – The integrated design of the test oxygen bomb assembly greatly shortens the oil-gas pressure test pipeline, making pressure detection more accurate. The high‑sealing manual needle valve ensures operational safety and excellent sealing, leading to more reliable test results.
Data export – After the test, data can be exported via a USB flash drive and post‑processed on a computer, supporting paperless, environmentally friendly office work.

Working Principle & Software Features

The gasoline oxidation stability tester operates by accelerating the oxidation process of a gasoline sample in an oxygen bomb filled with pure oxygen at 100 °C. The instrument continuously monitors the pressure drop inside the bomb, which indicates the absorption of oxygen by the sample. The induction period is automatically determined as the time required for a specified pressure drop to occur. A dedicated testing software not only displays real‑time pressure curves but also allows automatic calculation of the induction period, data storage, historical data retrieval, and report generation. The user‑friendly interface supports multi‑bomb simultaneous testing (typically two bombs), improving testing efficiency. Additionally, the software includes alarm functions for overpressure or temperature deviation, ensuring safe and unattended operation.
