Introduction

Hydrolytic stability is an important performance indicator for hydraulic fluids. It reflects the ability of hydraulic oil to resist chemical decomposition when exposed to water and elevated temperature. Poor hydrolytic stability may lead to the formation of acids, sludge, corrosion products, and deterioration of hydraulic system performance.

This Hydrolytic Stability Tester is suitable for testing both mineral-based hydraulic oils and synthetic hydraulic fluids. During the test, oil and water are mixed under controlled temperature and rotation conditions, and the sample is evaluated for changes caused by hydrolysis.

The analyzer integrates automatic temperature control, automatic rotation, timer control, and alarm functions, providing reliable and repeatable test results for hydraulic fluid laboratories.

It is widely used in lubricant manufacturing plants, hydraulic oil laboratories, petroleum refineries, research institutes, and industrial quality control laboratories.

Typical Applications
