Transformer Oil Quality

A oil acid value tester is used to regularly assess the acidity of transformer oil to ensure it remains within acceptable limits.

Usage Requirements

The oil acid value analyzer should be placed on a stable and dry workbench, avoiding vibrations and direct sunlight exposure.

When using a magnetic stirrer, be sure not to set the stirring speed too high, as this may cause the solution to spill out.

Before use, the instrument should be cleaned, flushed, and calibrated to ensure accurate measurement. During use, please operate with care to avoid leakage or blockage.

Follow recommended cleaning procedures after each use, especially when testing viscous or reactive samples that can leave residues.

Routinely examine pumps, tubing, sensors, and electrodes for signs of wear, clogging, or corrosion.

A: We have more than 10 years of export experience. Please contact us to confirm if there is a local partner.

Q: What about the transportation?

A: Usually we take door to door express delivery ,cause it's more convenient and fast.

Q: What is oil acid value tester?

A: Oil acid value tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value.This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.

Q: What is the working principle of an oil acid value tester?

A: Sample Preparation: A small amount of oil or fat is weighed and dissolved in a suitable solvent, usually ethanol or a mixture of ethanol and diethyl ether.
Adding Indicator: A few drops of a color indicator, such as phenolphthalein, are added to the solution.
Titration Process: The device slowly adds a standardized KOH solution to the sample while stirring.
Measurement & Calculation: The device records the volume of KOH used. Using this data, it calculates the acid value, reflecting the free fatty acid content.
Result Display: The final acid value is displayed digitally, providing immediate insights into sample quality.

Q: How to choose the right oil acid value tester?

A: Accuracy and Precision: A tester's accuracy and precision are crucial for obtaining reliable acid value measurements.
Measuring Range: The tester should have a measuring range that covers the expected acid value of the sample being tested.
Sample Type: Some testers are designed specifically for liquid samples, while others can accommodate solid or semi-solid samples.
Ease of Use: The usability and simplicity of the tester's operation are important for efficient and accurate testing.

Q: Why is acid value measurement important for oils?

A: The acid value indicates the degree of oil oxidation or hydrolysis. A high acid value means the oil contains more free fatty acids, which can cause corrosion, sludge formation, and reduced lubrication performance. Monitoring the acid value helps maintain oil quality and extend equipment life.

Q: What solvent mixture is commonly used in testing?

A: A typical solvent mixture is ethanol-toluene or isopropanol-toluene in a 1:1 ratio, sometimes with a small amount of water or phenolphthalein as an indicator.

Q: Can the tester store or print test results?

A: Yes, most digital or automatic testers can store multiple test records, print reports, and export data via USB or network for laboratory documentation.
