– Precise Temperature Control, Stable Performance
In the quality control of automotive gasoline, aviation fuels, and turbine fuels, actual gum content is a key indicator for evaluating fuel stability, cleanliness, and engine deposit formation tendency. The DFYF-102 Petroleum Products Actual Gum Tester is designed and manufactured in strict accordance with the national standard GB/T 8019, making it suitable for determining the actual gum content in gasoline, aviation gasoline, aviation turbine fuels, and volatile distillates. It can also be used for rapid determination of unwashed gum content in automotive gasoline.
1. Standard Compliance and Applicable Samples
The DFYF-102 complies with GB/T 8019 / ASTM D381 and is suitable for the following sample types:
Automotive gasoline (including unwashed gum)
Aviation gasoline
Aviation turbine fuels
Volatile distillates and blended fuels
This method is widely used in refineries, quality inspection agencies, aviation companies, and third-party laboratories for evaluating fuel evaporation residues (gum content).

3. Performance Features
3.1 Metal Bath Heating System
The DFYF-102 adopts a metal bath heating system, which offers faster heating, better temperature uniformity, no oil fumes, and easy cleaning compared to traditional oil baths – significantly improving laboratory efficiency and environment.
3.2 Precision Manifold and Balanced Air Distribution
A built-in precision distribution manifold evenly splits the total air flow across all 3 ports. The total air flow is controlled by the system, eliminating the need for manual per-port adjustment. This simplifies operation and improves repeatability.
3.3 High-Quality Air Compressor for Stable Air Supply
The instrument is equipped with a high-quality air compressor, ensuring a stable air supply that meets the constant flow requirement of 600 mL/second per nozzle, providing excellent parallelism among test ports.
3.4 Intelligent Control for Easy Operation
Featuring a 5-inch LCD screen and an industrial-grade ARM 32-bit embedded processor, the DFYF-102 displays key parameters such as temperature and flow rate in real time. The user-friendly interface makes setup and operation straightforward.
4. Comparison with Traditional Oil-Bath Gum Testers
Feature | Traditional Oil-Bath Tester | DFYF-102 Metal Bath Tester |
Heating medium | Thermal oil | Metal bath (oil-free) |
Heating speed | Slow | Fast |
Temperature uniformity | Moderate | Excellent |
Cleaning & maintenance | Oil changes, leak prevention | Minimal, easy to clean |
