Introduction: WKT-A7 precision automatic trace moisture analyzer adopts international imported chips and integrates many advanced production technologies of our company. Calculation and display mode, automatic storage and printing after the measurement, the stored data can reach 500, which can quickly measure the moisture of gas, liquid and solid, the unique blank current automatic deduction function, and the high current local compensation function greatly improve the test accuracy of the instrument and The user experience is widely praised by users. Features: 1. The instrument adopts a single-chip computer and a computer composite control system, adopts double platinum electrodes, cross-current polarization detection, and intelligent analysis and measurement; 2. Automatically discharge waste liquid, the instrument automatically completes the injection of new reagents and discharge of waste reagents, and the test personnel do not need to contact the reagents; 3. LCD touch screen display, timely display the working status of the instrument; 4. The appearance is specially crafted, and the surface is treated by electrostatic spraying, which is anti-corrosion and easy to clean; 5. The blank current microprocessor automatically controls the compensation, and the reagent can quickly reach the equilibrium state; 6.400 mA large electrolytic current, high detection sensitivity and fast analysis speed; 7. Reagent life reminder function, when the reagent fails, the buzzer will remind you to replace the reagent! 8. Content calculation (5 formulas), 500 measurement results are automatically stored, and historical records can be consulted at any time; 9. The instrument automatically measures samples, automatically displays the analysis results, and can automatically calculate the average value of multiple measurements of the sample; 10. Automatically calculate and print ug/ppm/percentage/mg/L/sample name/experiment date, etc.; 11. Through the USB or RS232 interface of the instrument, it can communicate with notebook computers and microcomputers to realize network management; (optional) 12. Chinese and English operating systems are optional, and the instrument program can be upgraded when the national standard is revised; Technical parameter: Determination principle: Karl-Fischer Coulomb method (coulometric method) Electrolysis rate: 2.4 mg water/min Electrolysis current: 0-400mA automatic control Display measurement range: 0.1 micrograms of water - 200 milligrams of water Water content range: 0.0001% (1ppm) - 100% Sensitivity: 0.1 microgram water (μg) Accuracy: When the water content is between 100 micrograms of water and 1000 micrograms of water, the error is ≤±3ug; when the water content is above 1000 micrograms of water, the error is ≤±0.2% (excluding injection error) Display method: LCD large screen LCD touch screen Accuracy: 1μg-500μg ± 1 μg 0.1% above 500μg (excluding injection error) Drift Compensation: Microprocessor automatic control Stirring speed: independent control system, stepless speed regulation System calibration: Built-in automatic calibration program, directly set parameters to fine-tune the system gain coefficient, and can also calibrate with standard samples Analysis speed: The analysis speed is adjustable, set according to the sample characteristics and environmental conditions, and the electrolysis speed can be set freely End-point indication: On-screen display/Printout/Audio warning/End-point light indication Data input: touch screen operation input Sample number: user-defined Stored data: 500 Printing function: built-in low-power high-speed thermal printer, 56mm paper width Print Content: μg / ppm / mg/L / Moisture Percentage / Sample No. / Tester / Date Calendar/Clock: Analyze time, date display and print out Self-checking function: automatic diagnosis of instrument faults Linear correlation coefficient of moisture titration: ≥0.9998 Power consumption: less than 50W Dimensions: 350*310*125mm Use environment: temperature 5℃-40℃, humidity <85% Power supply: AC220V±10% 50HZ±2.5HZ Weight: 5KG
