Introduction: WKT-A2 "entry-level" automatic Karl Fischer trace moisture analyzer uses the principle of Karl Fischer Coulomb method (coulometric method) to quickly determine trace moisture in samples, measuring moisture as low as 1ppm, which can be determined within 1 minute The trace moisture of solid, liquid and powder is released. Friendly man-machine interface, 240*64 blue screen LCD display, full Chinese menu, detection circuit adopts digital processing technology, which overcomes the interference of temperature drift and power supply voltage fluctuation existing in traditional instruments on the test process, and improves the accuracy and sensitivity of the test. The whole machine adopts a relay-free process design, which eliminates the hidden danger caused by the oxidation of the memory relay contacts and prolongs the service life of the instrument. The instrument has a variety of built-in calculation formulas, which can directly display the % and ppm moisture of the sample, and has a printing interface. It can be equipped with a micro-printer, which is widely used in chemical, petroleum, medicine, electric power, food, scientific research, testing and other industries. Features: 1. The drift value is automatically memorized and the part affected by the drift is deducted, which is not affected by air or ambient moisture, and the reagent balance is fast 2. The stirring speed is adjusted by a physical knob, and the independent speed adjustment system is not affected by the program interface and state. 3. Special process design, the surface is treated by electrostatic spraying process, the core part is made of PTFE anti-corrosion material, easy to clean and anti-corrosion 4. The instrument status self-check, error self-check, and fault self-check function help users to deal with emergencies and meet the GLP experimental record standard. 5. Dual power channel design to suppress current interference 6. Built-in 4 commonly used water content calculation formulas. The percentage of the sample can be displayed directly. Optional micro-printer can print test results directly. 7. The data processing dual CPU design ensures the stability and accuracy of the instrument operation 8. 240*64 dot matrix LCD blue screen, real-time display of instrument working status, Chinese menu display, friendly people plan operation menu and key navigation 9. End-point buzzer and Chinese character prompts are better than the digital display of entry-level digital tubes at the same level 10. Year, month, day, week, hour, minute, second time display and correction, power failure does not affect 11. Built-in Chinese and English languages, other languages can be customized to facilitate the use of international friends. 12. In line with a number of national standards, suitable for all walks of life. Technical parameter: Measurement principle: Karl Fischer Coulomb method (coulometric method) Measurement speed: 33.5 μg H2O/s (max) Measuring range: 2 μg H2O to 130 mg H2O Measurement accuracy: When the water content is less than 10μg water microgram, the error is ≤±2μg, when the water content is above 10μg-500μg water, the error is ≤±5μg (excluding injection error) Standard ratio deviation ≤0.2% Measuring resolution: 0.1μg H2O Water content (concentration range): 1ppm-1000000ppm (0.0001%-100%) Electrolysis current: 0-400mA Stirring speed: knob type stepless adjustment Drift value blank value deduction: automatic deduction Special functions: end point delay, end point detection, gain coefficient correction, electrolysis rate adjustment, fault self-check prompt Display and operation: 240*64 blue screen LCD display Calendar/Time: Current time, date, detection time and date display End point indication: screen prompt / sound warning / end light indication Use environment: temperature 2℃-50℃, humidity ‹90% Power consumption: ≤30W Host size: 285mm*300mm*220mm Power supply voltage: 220V 50HZ 150W Weight: Host net weight 5kg
