Karl Fischer moisture meter ZKF-1

Karl Fischer moisture meter Model: ZKF-1 Instrument: Features: ⑴ high measurement accuracy - electrode polarization voltage control; the "fast - speed - slow - the end of the titration process, by high-brightness LED digital measurement results clearly show a resolution of 0.01ml. by a double platinum electrode polarization voltage to determine and display the end of the reaction, endpoint titration metering tube using sophisticated manufacturing capacity error ≤ ± 0.004 closed system to avoid environmental moisture . ⑵ penetrate a wide measurement range from 0.001% -100% moisture ⑶ simple operation - by simply pressing a function key, you can automatically complete reagent suction and discharge back to the liquid, measuring and solvent injection and waste using special The bottle adapters, can be easily implemented with conventional piping system containing (none) pyridine reagent bottles and solvent bottles connection keys: 1. Press the "Power" switch, the device will be in energized or de-energized 2. Press. " solvent "button automatically into the reaction solvent. 3. Press the" drain "button, the cuvette is automatically discharged waste into the waste container. 4. Press the" stirring "button, stir in the cuvette "stirring" or "stop" state. If in the "stirring" state, variable speed. 5. Press "ready" key, flat valve automatically switches to "ready" position knob to achieve. Karl Fischer reagent will be automatically inhalation metering tube, measured in preparation for the next step. 6. Press the "Back to the liquid" key, measuring tube's reagent card will automatically go back into the vial, the reagent can be uniform and balanced to ensure accuracy of the measurement. If the initial stage Press "Back liquid" button, to play the role of the exclusion of air to ensure test accuracy. 7. Press "measurement" key, flat valve automatically switches to the "determination" position, the device will automatically titration by the general amount of titration → microtiter → small microtiter automatic switching during the titration until the end of the reaction, the automatic stop titration, and automatic alarm, red light display, digital display capacity value of the reagent. 8. Press the "reset" key, you can abort the five, The 6,7 action, act as translators for the functional changes. Therefore, the operator has only to press the function key, the instrument will automatically achieve the desired function is activated, operation is very simple and reliable. · Patented reagent bottle adapter (patent No. .: 289219) * Using standard pyridine or pyridine-free reagent * High-brightness LED, clear display and if you make a mistake, can be interrupted immediately, and operate ⑷ protection of the environment and health - fully enclosed pipeline system. to a drying tube filled with silica gel to prevent the escape of atmospheric moisture to penetrate and eliminate toxic Karl Fischer reagent gases and protect human health. The Commission waste after measurement due to the presence of hazardous substances, must comply with environmental requirements for processing, to avoid adverse effects on the environment · instrument running smoothly, no noise C. Ambient conditions Temperature:.. 10 ~ 30 ℃ Relative humidity: ≤75% Power supply voltage: 220V ± 22V frequency:. 50Hz power supply must be grounded instrument should be placed stable work surface, to avoid glare, when not in use, in order to avoid optical response, should cast light shielding breathable outer cover. Measurement principle: Karl Fischer water determination capacity assay precision: a double platinum electrode polarization voltage to determine and display the end of the reaction, the termination of the titration titration resolution 0.01ml of water moisture titration titration reproducibility ≤0.01 linear correlation coefficient ≥ 0.998 manufactured using sophisticated measuring tube, capacity error ≤ ± 0.004 closed system to avoid environmental moisture penetration measuring range: 0.001% -100% (H2O mass fraction) simple: Press the relevant function key, the instrument can be achieved: Inhalation agents exclude air measurement systems, end display (alarm) Solvent waste water discharge mixing and variable speed suction patented reagent bottle adapter (patent number: 289219) using standard reagents pyridine or pyridine-free high-brightness LED, clearly shows that once the operation make a mistake, immediately interrupted and re-operate to protect the environment and health: a fully enclosed design of the piping system to avoid the escape of poisonous gas equipment running smoothly, no noise Specifications: 1. Measuring range: 0.001% -100% (H2O wt) 2. Resolution: 0.01ml 3. Moisture titration Repeatability: ≤0.01 4. moisture titration linear correlation coefficient: ≥0.998 5. capacity error ≤ ± 0.004 Main features: 1. By double platinum electrode polarization voltage discriminating end of the reaction, and terminate titration 2. closed system to avoid environmental moisture penetration 3. microtiter design, the water content can be measured to 0.001% 4. Using patented test (solvent) bottle fitting, easy to replace 5. High brightness LED, clearly show the measurement data
