MDZY-KLKHF Karl Fischer moisture meter adopts a unique needle design, which can realize carrier gas input and water vapor output in one operation. At the same time, due to the new gas circuit design, the instrument can realize the transmission of water vapor with a very small flow rate. Moreover, only the sample bottle needs to be replaced each time the sample is injected, and the operation is simple and convenient.
Application Field
1,Trace moisture detection, detection accuracy can reach ppm level. It is very suitable for industries that have high requirements for moisture detection, such as lithium batteries, plastics, and petrochemicals.
2,For product moisture detection with limited sample size, the minimum 20mg can be tested (the sampling weight is determined according to the moisture content of the sample). It is suitable for industries with expensive samples and limited product quantities, such as medicine.
3,The products that produces various volatiles upon heating. These products are mainly concentrated in the chemical industry.

Product Features
1,The combination of high-precision coulometric moisture analyzer and karl heating furnace can detect water at a minimum of 3μg, and the accuracy can reach ppm level;
2,The maximum temperature is 300℃, which can meet the detection of most samples. Air flow 0-100ml, can be adjusted freely, suitable for products with various moisture release rates.
3,Hollow core gas needle injection technology and gas delivery management design with heating function, so that the water with zero dead volume will not condense. While simplifying the operation steps, it also improves the accuracy and repeatability of the instrument.
4,Headspace sampling technology. During the test, a new round of measurement can be started just by replacing the sample bottle, without transferring the sample, the operation is simple, and the measurement efficiency is greatly improved. At the same time, the sample bottle is always kept sealed, and the sample will not be disturbed by moisture in the air, which ensures the accuracy of the measurement results. In addition, because a new vial is used for each measurement, cross-contamination between samples does not occur.
5,Headspace sampling technology. Only the gas enters the reaction cup and does not contaminate the reaction cup and electrolysis electrodes.
6,High-definition capacitive touch screen, the menu is concise and clear, the operation is convenient and fast, and the measurement parameters can be displayed in real time.
7,5 kinds of measurement methods and 8 kinds of calculation formulas are available for selection, which is convenient for the detection of various samples. Custom units are: %, ppm, mg/kg, etc.;
8,The system detects the moisture in the environment in real time, and will accurately deduct the drift. At the same time, the real-time dynamic impedance method is used to determine the end point of the titration to ensure more accurate measurement results.
9,The test operation is simple and convenient. Just set the parameters such as temperature and flow, put the sample into the prepared sample bottle, put the sample bottle in the heater, then stick the transfer needle into the silicone pad of the sample bottle, and click on the instrument to start the measurement.
