Analysis of the use and maintenance of the electrolytic cell of trace moisture analyzer The trace moisture analyzer is also called Karl Fischer moisture analyzer. There are similar moisture analyzers, moisture analyzers, moisture meters, moisture detectors, moisture meters, and moisture analyzers. definition It is mainly used for the detection of samples with low moisture content. After continuous improvement, the accuracy is greatly improved and the measurement range is expanded. Features and parameters Using 320 * 240 graphic dot matrix LCD screen and touch keys; using a constant current source electrolysis circuit to reduce the power consumption of the instrument; optional battery; High-precision measurement electrode signal generation and detection circuit; use electrolyte blank current compensation, balance point drift compensation and other methods to correct the measurement results; The measurement electrode signal is displayed in the form of a bar graph on the liquid crystal display, which intuitively indicates the water content of the electrolyte; the electrolysis speed is plotted in real time during the electrolysis process. The user can monitor the entire process of electrolysis and can judge based on this curve Whether the electrolyte has failed; 10-stage stirring speed adjustment; 10-stage electrolytic gain adjustment; with automatic detection function of measuring electrode open circuit fault and short circuit fault; Automatically store historical records with time stamps, up to 500; with a calendar clock, accurate travel time, automatically record the time and date of sample measurement, can run for more than 10 years in a power-off state; leave a USB interface for easy communication with the computer . Accuracy: water content less than 1000ug, allowable error ± 3ug; water content greater than 1000ug, allowable error 0.2%; (excluding sampling error) Resolution: 0.1ug Maximum electrolysis speed: 2.4mg / min; Point solution current: 0-400mA; Power supply voltage: AC220V ± 20%; Maximum power consumption: 30W Operating ambient temperature: 5-35 ℃; Operating ambient humidity: ≤85 %; Dimensions: 350 * 260 * 180mm; Weight: 6KG Use and Maintenance of Electrolysis Cell of Trace Moisture Analyzer Step 1: Treat the electrolytic cell. Gently shake the electrolytic cell of the trace moisture analyzer a few times so that the water on the inner wall of the cell bottle is fully absorbed by the electrolyte, then put the electrolytic cell in the holder, turn on the stirring switch, adjust the stirring speed, and make the liquid surface A small vortex; insert the measuring electrode plug and the electrolytic electrode plug into the corresponding sockets of the host, and make good contact, turn on the electrolytic switch. Note: In the state of iodine, the green lights of the measuring signal indicator and the electrolytic signal indicator are all off, only one red light is lit, and the digital display does not count.
