DFYF-113 Rust Prevention Characteristics Tester (Liquid Phase Rust)

2026-04-29


Precisely evaluate the anti‑rust capability of oils to protect metal components

When lubricating oils, hydraulic fluids, turbine oils, and similar products become mixed with water, insufficient rust protection can quickly lead to corrosion of ferrous parts and subsequent equipment failures. Designed in strict accordance with GB/T 11143 and ASTM D665, the DFYF‑113 Tester assesses the ability of mineral oils and other fluids to prevent rust on iron surfaces in the presence of water. Featuring four independent test stations, a high‑precision constant‑temperature bath, and a stable stirring system, this instrument is an ideal tool for oil development and quality control.


Key Advantages

✔ Dual‑standard compliance – globally recognized
Meets both GB/T 11143 and ASTM D665 standards, ensuring results are accepted worldwide – suitable for import/export inspection, arbitration analysis, and in‑house quality control.

✔ Four independent test positions – efficient parallel testing
The benchtop unit offers 4 test stations, allowing simultaneous testing of multiple samples or replicates. This significantly boosts throughput for laboratories handling large numbers of samples.

✔ High‑accuracy constant‑temperature bath – uniform thermal field

  • Temperature range: ambient to 99.9 °C

  • Temperature accuracy: ±0.1 °C

  • Stainless steel bath – corrosion‑resistant, easy to clean, long service life

  • Dedicated bath stirring motor (1350 r/min) ensures even temperature distribution across all stations, guaranteeing consistent conditions.

✔ Precise and stable sample stirring system

  • Sample stirring speed: 1000 ± 50 r/min

  • Belt‑driven transmission for accurate, smooth rotation with minimal manual intervention

  • Simulates an oil‑water mixture state, realistically reflecting rust‑preventive performance under dynamic conditions.

✔ Built‑in polishing device – all‑in‑one convenience
The tester includes a dedicated polishing motor (1750 r/min) and an abrasive unit for preparing test specimen surfaces before testing – no extra equipment needed, streamlining the workflow.

✔ Smart temperature control – intuitive operation
Digital temperature controller provides precise regulation and easy reading. Combined with bath stirring, the temperature control circuit maintains a constant bath medium temperature, allowing users to obtain repeatable results effortlessly.Liquid Phase Rust Prevention Characteristics Tester
