1、 Main characteristics of the instrument

1. The core host adopts TI's AM3354 processor, Cortex-A8 core, and a 1GHz clock speed; The operating system adopts Windows Embedded Compact 7 real-time industrial control system. Thoroughly abandoning the use of nuclear free and non operational microcontrollers, the modernization of instrument control has been truly achieved, ushering instruments into a new era of intelligence.

2. The monitor adopts the original 7.0-inch 800 × 480 pixel true color TFT-LCD display screen from Innolux; The keyboard adopts a human body sensing touch screen. The fully Chinese operating interface displays delicate, intuitive, and elegant graphics, making it easy to control and touch freely.

3. It has the function of setting parameter storage, and after power failure, it can be restarted to maintain the last parameter settings.

4. The refrigeration system adopts a cascade refrigeration system composed of imported Sikepu compressors to cool the cold bath, which is more energy-efficient and efficient than semiconductor refrigeration.

5. The cold bath temperature detection adopts the original PT100 platinum resistance temperature sensor, combined with high-precision AD converter, excellent linear mathematical model, and unique control algorithm to control the electric heating tube, making temperature measurement and control faster, more accurate, and stable.

6. The sample temperature detection adopts the original PT100 platinum resistance temperature sensor, combined with a high-precision AD converter, making temperature acquisition more accurate and stable, with an accuracy of ± 0.1 ℃.

7. The instrument is equipped with an imported non visible photoelectric liquid level detection sensor and a built-in timer. After pressing the button, it automatically performs suction, timing, and detection to determine whether the cold filter point has been reached.
