– Metal Bath, Fully Automatic, Compliant with GB/T 8018 / ASTM D525
I. Applicable Standard & Application
Strictly designed and manufactured in accordance with GB/T 8018 “Test method for oxidation stability of gasoline (induction period method)” and ASTM D525. It is specifically used to determine the induction period of motor gasoline, ethanol gasoline, blended fuels, etc., under accelerated oxidation conditions, thereby evaluating their oxidation stability. Widely applied in petroleum refining, quality inspection, fuel storage & transportation, and research institutions, this instrument is key equipment for judging the storage stability and anti-oxidation capacity of gasoline.

III. Key Features
1. Metal Bath – Eco-friendly & Convenient
Replaces the traditional water bath with a metal bath. No water filling, no pipeline blockage or leakage risks, and no contamination. Eliminates daily water maintenance, making operation simpler and safer.
2. Integrated Sealed Oxygen Bomb Assembly
The test oxygen bomb adopts an integrated structure, greatly shortening the oil-gas pressure measurement line, reducing pressure transmission loss, and ensuring more accurate pressure detection. Combined with high-seal manual needle valves, it guarantees zero leakage throughout the test, providing reliable results.
3. Real-time Pressure Curve Monitoring
During the test, the system displays real-time pressure curves from two independent oxygen bombs, allowing easy observation of the induction period inflection point and timely tracking of the oxidation process.
4. Fully Automatic Computer Control
Adopts computer automatic control technology to automatically perform detection, calculation, and control. The 7-inch touch screen embedded system offers a user-friendly interface and stable operation. One-key start with automatic judgment of the induction period endpoint greatly reduces manual attendance time.
5. Data Storage & Paperless Office
After the test, data can be directly exported via USB flash drive and processed on a computer, enabling paperless testing that meets the green office requirements of modern laboratories.
6. Excellent Thermal Insulation System
The instrument body features high-efficiency thermal insulation, saving energy while effectively preventing operator burns, making it safer to use.
IV. Typical Applications
Refinery gasoline quality control for oxidation stability
Regulatory spot checks of commercial gasoline by quality inspection authorities
Storage stability evaluation of fuels by storage & transportation companies
Rapid screening of antioxidant effectiveness by additive R&D units
Commissioned testing by third-party laboratories
V. Test Principle (Brief)
The sample is subjected to accelerated oxidation at an oxygen pressure of 700 kPa and a temperature of 100℃. The time (in minutes) required for the oxygen pressure to drop from its maximum to a specified value (typically a drop of 14 kPa) is measured — this is the induction period. A longer induction period indicates better oxidation stability and greater resistance to gum formation.
