This instrument complies with regulations such as GB/T264, GB7599, and GB/T7304. It can accurately detect the acid value of petroleum products such as lubricating oil, transformer oil, turbine oil, fire-resistant oil, diesel oil, and gasoline. It is widely used in industries such as chemical industry, electric power, railway, and petroleum.

Meet the standards：

GB/T 264-1983 Method for Determination of Acid Value of Petroleum Products

GB7599-87 Method for Determination of Acid Value of Transformer Oil and Turbine Oil in Operation

GB/T7304-2000 Test Method for Acid Number of Petroleum Products and Lubricants

Instrument Features：

1、Based on the neutralization method principle, the STM microprocessing chip automatically controls and fully automatically analyzes and determines the acid value of samples；

2、10-inch color Chinese-English touch screen display, the detection system uses laser components with low power and high precision;

3、It can be connected to a [balance] for weighing, with data automatically transmitted to the instrument, which then automatically calculates the acid value result of the sample.

4、Functions such as automatic liquid adding, titration, stirring, titration endpoint judgment, storage, and result printing of the instrument;

5、Data can be imported into a USB flash drive through the instrument’s USB interface, and internal data can be transferred and imported into a computer, making it convenient for querying and printing.

6、Neutralization titration alarm self-check function, automatic detection function for extractant加注, preventing liquid shortage and overflow, and ensuring test accuracy;

7、Powerful storage function: the instrument has an internal storage capacity of 1000 data records and can be externally expanded to 500G storage.

8、Automatically clean the pipelines, prevent pipeline blockage, no bubbles, and improve the service life of the pipelines;
