Industrial Oxidation Test Apparatus: A Precise and Efficient Solution for Testing the Oxidation Stability of Insulating Oil

DESCRIPTION / TECHNICAL SPECIFICATIONS

Precision Oxidative Stability Testing Solution for Mineral Insulating Oils

In power generation, lubricant manufacturing, and industrial quality control laboratories, maintaining the integrity of insulating oils is essential for protecting critical electrical and mechanical assets. The Oxidation Test Apparatus is a professional laboratory testing instrument engineered to determine the oxidative stability of unused mineral insulating oils containing inhibitors. Furthermore, this apparatus is utilized to evaluate the tendency of unused mineral insulating oils to form acids and precipitates both before and after the induction period.

Standardized Testing Mechanism and Reliable Measurement

The Oxidation Test Apparatus operates on a strictly controlled and standardized testing mechanism. During the test, the oil sample is maintained at a constant temperature of 120°C in the presence of a copper catalyst coil while a continuous, steady flow of oxygen is passed through it. The instrument measures the exact time required for the volatile acid generated by the oxidation of the sample to reach a neutralization value equivalent to 0.28 gKOH/g. The oxidative stability of the tested oil sample is then accurately represented by the induction period measured in hours (h).

High Testing Efficiency for Industrial Laboratories

Designed to maximize laboratory throughput and testing productivity, the Oxidation Test Apparatus features 6 working units capable of performing six tests simultaneously, organized into two groups of three samples each. This multi-sample capability significantly reduces turnaround time for batch quality verification. In addition, the system utilizes metal bath heating driven by electric heating rods, offering a safe and environmentally friendly alternative to conventional liquid bath systems.
