Introduction：
Automatic Acid Value Tester measures the acid value of petroleum products by the reflux method with automatic titration, cleaning and drying. Widely used for petroleum, power and chemical industries for oil quality control....
Fully automatic reflux method with automatic cleaning and automatic blow-drying.
1. 7-inch color touchscreen operation, microcomputer automatic control.
2. The detection system adopts advanced laser components and a high-precision RGB color sensor, with low power and high precision.
3. Automatically controls the whole acid value titration process and automatically determines the color end point.
4. Program-controlled temperature heating bath with automatic boiling reflux.
5. Automatic waste liquid discharge and reaction bottle cleaning after the test.
6. Automatic data query function for convenient search and printing; stores 500 historical records.
7. Applicable to standards such as GB/T 28552-12, GB/T 264-83, GB/T 7599-87 and GB/T 258-16.
8. Applicable oil samples: transformer oil, turbine oil, phosphate ester fire-resistant oil, lubricating oil, hydraulic oil, etc.
1. Method: reflux method principle.
2. Measurement range: 0.001-2.0 mgKOH/g.
3. Resolution: 0.001 mgKOH/g.
4. Measurement error: sample acid value (mgKOH/g) vs. error (mgKOH/g) - <0.1 / <0.01; 0.1-0.3 / <0.02; >0.3 / <0.03.
5. Repeatability error: ≤±0.01 mgKOH/g.
6. Temperature control accuracy: ≤±0.1 °C.
