DFYF-104Z Petroleum Products Vapor Pressure Tester (Reid Method)

– Double-Bomb Automatic Rotation, Compliant with GB/T 8017 / ASTM D323

I. Applicable Standard & Application

Strictly designed and manufactured in accordance with GB/T 8017 “Test method for vapor pressure of petroleum products (Reid method)” and ASTM D323. It is specifically used to determine the Reid saturated vapor pressure of gasoline, volatile petroleum products, diesel, and other liquid fuels. Widely applied in petroleum refining, quality inspection, fuel storage & transportation, and third-party testing laboratories, this instrument is essential for evaluating fuel volatility and safety.

II. Key Technical Specifications

III. Key Features

1. Fully Automatic Intelligent Control

Equipped with a 7-inch LCD touch screen and an industrial-grade ARM 32-bit embedded core processor, the instrument automatically completes the entire test process. After reaching the set temperature, one-key start initiates automatic rotation of 350° and reversal after a constant temperature period – no manual intervention required.

2. Dual-Bomb Independent Testing

Includes two standard test bombs allowing two parallel or comparative tests simultaneously, improving efficiency. Each bomb is independently sealed and monitored for pressure, ensuring reliable data.

3. Large-Circulation Stirring & Uniform Temperature Field

A large-circulation stirring pump inside the bath ensures uniform temperature throughout the bath, meeting the strict control requirement of 37.8℃±0.1℃.

4. Automatic 350° Rotation & Reversal

The test bombs automatically rotate 350° and reverse, simulating the shaking operation specified in the Reid method. This achieves full gas-liquid equilibrium and ensures pressure measurement accuracy.

5. Safety Protection & Fault Diagnosis

The instrument incorporates multiple safety features:

Automatic temperature and pressure correction / calibration

Fault alarm and indication

Gas path leak detection – immediate alarm upon leakage

Safe, reliable, and highly automated operation

6. Data Export & 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.

IV. Typical Applications

Refinery quality control of vapor pressure for gasoline, naphtha, and other products

Regulatory spot checks of commercial gasoline by quality inspection authorities

Evaporation loss assessment for fuel storage & transportation companies

Rapid screening of formulation volatility by additive manufacturers

Commissioned testing by third-party laboratories

V. Test Principle (Brief)

A fixed volume of liquid and vapor sample is placed into a Reid test bomb, sealed, and immersed in a constant-temperature bath (or metal bath) at 37.8℃. The bomb is shaken periodically until the pressure stabilizes. The saturated vapor pressure inside the bomb at that time is the Reid vapor pressure (in kPa). A higher vapor pressure indicates greater fuel volatility and increased safety risk.
