1. Large LCD screen, Chinese menu, unmarked buttons.

2. Automatic cup change, automatic detection, and printing of test results (optional automatic timed heating function, suitable for lubricating oils with high viscosity).

3. The instrument can test six oil samples.

4. Using the principle of neutralization method, the microcomputer is used to automatically complete liquid addition, titration, stirring, and determination of the titration end point at room temperature. The LCD screen displays the measurement results and can print out. The whole process takes about 4 minutes.

5. The extraction liquid and neutralization liquid are contained in special reagent bottles. The reagents do not come into contact with the air during use to avoid solvent volatilization and the influence of CO2 in the air.

Applicable standards: GB/T264 GB/T258

A1040 automatic acid value tester is used to test the acid value of transformer oil, turbine oil and fire-resistant oil.
