It adopts an original imported 7.0-inch 800*480 pixel true-color TFT-LCD large-screen color display, with a human-sensing touchscreen keyboard, a fully Chinese operating interface, and an intuitive and user-friendly software interface. The interface is rich in content, easy to operate, and features Chinese character prompts, high detection sensitivity, simple operation, fast testing speed, and good repeatability.
1. The instrument has test result storage, printing, and calculation functions. The sample determination process is automatically controlled by the instrument, with stirring and measurement completed automatically in approximately 60 seconds, directly displaying the results. The fully sealed titration bottle avoids contact between reagents and personnel, and also avoids the influence of environmental humidity. The instrument features a Chinese LCD display and automatic calculation and printing functions, capable of printing percentage content, sample number, tester, and experiment date. The instrument’s accuracy is: ① When the water content is less than 10 micrograms, the measurement error is less than 2 μg of water; ② When the water content is between 10 and 1000 micrograms, the measurement error is ≤2 μg of water; ③ When the water content is above 1000 micrograms, the measurement error is ≤0.2% (excluding injection error).
2. The core host uses a TI AM3354 processor with a Cortex-A8 core and a 1GHz clock speed; the operating system is Windows Embedded Compact7 real-time industrial control system. This completely abandons the bare-bones microcontroller without a core or operating system, truly modernizing instrument control and ushering the instrument into a new era of intelligence.

Instrument Features：

Capable of micro-analysis of low-content samples with high sensitivity.
Can store 20,000 experimental results; employs unique alternating balance isolation detection technology, making balance detection faster, more accurate, and more stable; the electrolysis circuit uses advanced PWM pulse width modulation technology, significantly reducing overall power consumption.
User-friendly human-machine interface with a touchscreen interface.
Clock display (year, month, day, hour, minute, second), retains information even after power failure.
Printer: Embedded thermal printer, 36 characters, Chinese character output; quieter, faster, and clearer printing.
Program-controlled, allowing direct digital input from the interface to adjust the stirring speed.
Multiple formula selections, automatically changes display units (ug, mg/L, ppm, %), and can be memorized.
