WM-4000B Petroleum Product Cold Pour Point Tester Introduction
WM -4000B petroleum product freezing point pour point cloud point cold filter point tester is developed in accordance with national standards GB / T510, GB / T3535, SH / T0248, GB / T6986. It can be used for the condensation of oil products and chemical raw materials. It is widely used in pharmacopoeia, petroleum, chemical engineering, scientific research, and measurement departments. Features
The core host adopts TI's AM3354 processor, Cortex-A8 core, 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.
The display uses Innolux's original 7.0-inch 800 x 480-pixel true-color TFT-LCD display; the keyboard uses a human-sensitive touch screen. Full Chinese operation interface, exquisite and intuitive display, easy to operate and free to touch.
The control program interface is designed with temperature setting value rapid addition and subtraction operation buttons, which makes the temperature setting and changing process more streamlined, fast, efficient and free.
Equipped with setting parameter storage function. After power off, restart the machine to keep the last parameter setting.
The refrigeration system adopts a cascade refrigeration system composed of imported Secop compressors to cool the cooling bath, which is more energy-efficient and efficient than semiconductor refrigeration.
The temperature detection uses the original PT100 platinum resistance temperature sensor, coupled with high-precision AD converter, excellent linearized mathematical model and unique control algorithm to control the electric heating tube, making the temperature measurement and control faster, accurate and stable.
The bath has a built-in stirrer, which makes the temperature distribution in the bath uniform and the temperature control effect is excellent.
The instrument is equipped with 2 experimental ports, one of which has a function of 45-degree tilt clamping and test tube clamping, which can realize 45-degree tilt and angle maintenance of the test tube. Technical Parameters
