WM660 automatic volume resistivity tester Features
1.Implement power standard DL421. Widely used in petroleum, chemical, metallurgy, power, transportation, commodity inspection and scientific research departments.
2.The core host uses a 100MHZ high-speed single-chip computer with a display driver module, keyboard scanning module, ± 5ppm high-precision clock module, RS-232 serial communication module, NVM data storage module, output control module, buzzer alarm module, etc. , Complete functions.
3.The display uses 5.0-inch 480 x 272-pixel true-color TFT-LCD LCD screen imported from the original, with full Chinese operation interface, exquisite and intuitive display.
4.The keyboard uses human-sensitive touch keys, no mechanical contacts, dust and water resistance, anti-radio frequency interference, and longer service life.
5. Historical data storage adopts NVM data storage storage, which can store 256 historical data, and the data can be stored for 10 years without loss.
6.The printer uses an embedded thermal printer to print quieter, faster and clearer.
7.Resistance (volume resistivity) measurement uses advanced detection and amplification circuit, automatic pressure (500V.DC), automatic range switching, convenient, fast, accurate and reliable.
8.The temperature measurement and control uses the original imported PT100 platinum resistance temperature sensor, high-precision AD converter, excellent linearized mathematical model, and unique control algorithm, which makes the temperature measurement and control faster, more accurate, and more stable.
9.Three-cup structure can measure volume resistivity at the same time.
10.Automatically complete operations such as pressurization, switching, detection, calculation, and printing. Technical Parameters
