WM-215A Automatic Acid Value Tester Features
1. This instrument is designed and manufactured according to national standards GB / T264-83 and GB / T7599-87. It is mainly suitable for measuring the acid value of petroleum products such as transformer oil and steam turbine oil. Can be widely used in power, petroleum, chemical, commodity inspection, scientific research and measurement departments.
2. The core host uses TI's AM3354 processor, Cortex-A8 core, and 1GHz frequency; the operating system uses Windows Embedded Compact 7 real-time industrial control system. Completely abandoning the non-nuclear and non-streaking streak single-chip microcomputer, truly realizing the modernization of instrument control, making the instrument enter a new era of intelligence.
3. The display uses Innolux's original 7.0-inch 800 x 480-pixel true-color TFT-LCD display; the full Chinese operation interface displays a delicate and intuitive display.
4. The capacitive touch screen is used for operation, which has the advantages of no mechanical loss, dust and water resistance, anti-radio frequency interference, and long service life.
5. Historical data storage adopts FLASH data memory storage, which can store 2010 historical data. The data can be stored for 10 years without loss, and the stored data cannot be changed.
6. Equipped with setting parameter storage function. After power off, restart the machine to keep the last parameter setting.
7. The printer adopts a miniature embedded thermal printer, which is quieter, faster and clearer. It can also be customized as a dot-matrix printer. The printed results can be stored for a long time without fading.
8. The rear USB interface can be used for later software updates, or you can connect a mouse for precise operation.
9, using the principle of neutralization, using computer control at room temperature to automatically complete the extraction, stirring, neutralization calculations, printing reports and other steps.
10.Using a high-precision peristaltic pump to automatically inject extraction, neutralize reagents and accurately record the injection amount
11, with automatic neutralization calculation, endpoint detection and judgment functions.
12. There are 7 test cup holes in the instrument, of which 6 are experimental hole positions, and the remaining 1 is used for initial emptying.
13. The built-in magnetic stirring system enables the sample to be fully extracted and neutralizes the color at the time of titration, making the detection more accurate. Technical Parameters
