Automatic Water Soluble Acid Value Tester

DescriptionThis instrument is designed and manufactured according to GB/T 7598-2008 <Determination of water soluble acid in running transformer oil and turbine oil (colorimetric method)>, and is specially used for the determination of water soluble acid (pH) in transformer oil, turbine oil, fire-resistant oil and other petroleum products. The instrument has a high degree of automation. After the operator manually injects the oil sample and water according to the standard, and the instrument will perform heating, oscillation, oil-water separation, extraction of double water samples, automatic dropping of bromocresol green and bromocresol violet indicators, color development and colorimetric determination in strict accordance with the order specified in the standard, and displaying the determination results.
The instrument can improve the working efficiency and test accuracy, reduce the user's contact with samples and reagents, and ensure the personal safety to the maximum extent.
The instrument can measure 1-3 samples at a time. The user can choose the number of test cups according to their own requirements. It is easy to use and operate.
