Pain Point:
For lubricating oil, turbine oil, and hydraulic oil suppliers, the biggest risk is not the oil itself, but rust damage caused by moisture contamination during storage, transportation, or operation. When end-users find rust on metal components, they often blame the oil quality. But how can you prove your oil has sufficient rust prevention capability before leaving the factory?
Our Solution:
The DFYF-113 Rust Prevention Performance Tester allows you to simulate real working conditions in your lab. By mixing 300mL of your oil sample with 30mL of distilled or synthetic seawater, and immersing a standard steel rod at 60°C for 24 hours, you can visually verify whether your oil provides effective rust protection.
Customer Value:
You no longer rely on “experience” or “supplier claims.” You get objective, verifiable data to prove product quality, reduce customer complaints, and avoid costly claims.
Parameter | Value | Why It Matters to You |

Heating Power | 1000W | Fast heating to test temperature, saving waiting time |
Temperature Range | Room temp ~ 99.9°C | Covers standard test at 60°C and other custom requirements |
Temperature Accuracy | ±0.1°C | Ensures test repeatability and meets ASTM/GB standards |
Sample Stirring Speed | 1000 ± 50 r/min | Precisely simulates oil-water mixing during real operation |
Polishing Motor Speed | 1750 r/min | Built-in polishing device for standard test rod preparation |
Bath Stirring Speed | 1350 r/min | Uniform temperature distribution across all test positions |
Test Stations | 4 stations (bench-top) | Run 4 samples simultaneously, increasing lab efficiency |
Applicable Standards | GB/T 11143, ASTM D665 | Globally recognized methods for rust prevention testing |
4 Independent Test Stations
Unlike single-station testers, the DFYF-113 allows you to run four different oil samples at the same time. This reduces total test time by 75% and increases lab throughput.
Precision Stirring with Belt Drive
The sample stirring motor uses a belt transmission system, ensuring stable and accurate rotation speed (1000±50 r/min) without manual intervention. Results are consistent every time.
Built-in Polishing Device
No need for separate polishing equipment. The integrated 1750 r/min polishing motor prepares test steel rods according to standard requirements, saving bench space and operator time.
High-Stability Stainless Steel Bath
The corrosion-resistant stainless steel bath maintains uniform temperature across all four test positions, eliminating “cold spots” that could skew results.
Digital Temperature Control
The digital PID controller provides real-time temperature display and precise control (±0.1°C), meeting the most stringent lab requirements.
Scenario 1: Turbine Oil Manufacturer – Quality Assurance
A turbine oil supplier in Germany uses the DFYF-113 to test every batch before shipment. By following ASTM D665, they confirmed their oil passed the 24-hour rust prevention test, reducing customer claims by 30% in one year.
Scenario 2: Hydraulic Oil Lab – Incoming Raw Material Inspection
An independent testing lab in Singapore uses the DFYF-113 to verify additive performance. They run four samples simultaneously – different additive concentrations – to quickly identify the most cost-effective formulation.
Scenario 3: Marine Lubricant Supplier – Custom Test Conditions
A marine lubricant supplier in South Korea requested a 48-hour test cycle instead of the standard 24 hours. The DFYF-113’s extended temperature stability and stirring accuracy allowed them to meet their customer’s special requirement.

Q1: Can the DFYF-113 use synthetic seawater instead of distilled water?
A: Yes. The DFYF-113 is designed to work with both distilled water (ASTM D665 A) and synthetic seawater (ASTM D665 B). You can choose based on your application.
Q2: How long does one test cycle take?
A: The standard test cycle is 24 hours at 60°C. However, you can customize the test duration based on mutual agreement between buyer and seller.
Q3: What is your delivery time?
A: Standard delivery is 20–25 working days after order confirmation. For urgent needs, please contact us to check current stock.
Q4: Do you provide installation support?
A: Yes. We provide an English user manual and installation video. Remote technical support is available 24/7. On-site training can be arranged for bulk orders.
Q5: What is your warranty policy?
A: 12 months from the date of shipment, excluding consumables. Lifetime technical support is included.
Q6: Can I run four different oils at the same time?
A: Yes. The four test stations operate independently, allowing you to test four different samples or four different conditions simultaneously.
