— *High-Precision Temperature Control, Compliant with ASTM D1402 / GB/T 7305*
In the quality evaluation of petroleum synthetic fluids, hydraulic oils, turbine oils and similar products, demulsibility (oil-water separation ability) is a key physical indicator. The DFYF-124 Petroleum Synthetic Fluids Demulsibility Tester is strictly designed according to GB/T 7305 and ASTM D1402 standards, specifically for determining the ability of synthetic fluids to separate from water. With ±0.1°C temperature control accuracy and a stable stirring system, it provides accurate, repeatable test results for laboratories.
Core Advantages
✅ Dual-Standard Compliance – Globally Accepted
Simultaneously complies with GB/T 7305 and ASTM D1402, ensuring reliable data for quality control and R&D of lubricating oils, synthetic fluids and hydraulic oils worldwide.
✅ Ultra-High Temperature Control Accuracy – More Trustworthy Results
Temperature range: ambient ~ 99.9°C
Control accuracy: ±0.1°C (far superior to conventional products)
Digital temperature controller + solid-state relay provides extremely low bath temperature fluctuation, ensuring constant test conditions.
✅ Precise Stirring Speed – Meets Standard Requirements
Stirring motor speed: 1500 ± 15 r/min, fully complying with the shear rate requirements of the standards, ensuring uniform oil-water mixing and excellent repeatability.
✅ Two-Cylinder Design – Increases Efficiency
The bath can accommodate two graduated cylinders simultaneously, enabling parallel sample testing or comparative analysis of different samples, saving experiment time.
✅ Flexible Adjustable Stirring Assembly
The sample stirring device can be moved up and down, allowing easy adjustment of the stirrer blade position inside the cylinder to suit different liquid levels – simple and convenient operation.
✅ User-Friendly Auxiliary Functions
Built-in illumination: clearly observe the oil-water interface and emulsion condition.
Timer with audible alarm: automatically alerts when the set time is reached – no need for constant operator attention.
