Product Overview

Weike MeituoThe WKT-C9 fully automatic Karl Fischer moisture analyzer utilizes the principle of Karl Fischer volumetric method to quickly determine the moisture content in samples. The moisture content can be measured as low as 10ppm, and the moisture content of solids, liquids, and powders can be determined within 30 seconds. The instrument comes with an RS232 serial port that can be connected to peripheral devices such as printers, scales, and computers. It can store 200 sets of data and can be queried in real time! C9 is another upgrade of the moisture analyzer based on Vicote's intelligent model, with higher automation and precision. WKT-C9 meets multiple national and international moisture determination standards, complies with pharmacopoeia requirements, and is widely used in industries such as chemical, petroleum, pharmaceutical, power, food, batteries, plastics, scientific research, and testing.

Product Operation

Operation steps:
Reagent debugging steps:
First, assemble the card type moisture analyzer and connect it to the power supply. Turn on the power switch
1. Suck methanol (other co solvents) until the liquid level covers the platinum tip of the electrode
2. Let the instrument perform a blank operation to deduct excess water from methanol (other solvents)
3. Perform multiple calibrations on the Karl Fischer reagent we use (more than 3 times, it is recommended to use deionized water or standard samples for calibration, or standard water samples for calibration)
4. After calibration, sample measurement can be carried out
Sample determination steps:
1. After sampling with an injector, place it on an analytical balance and weigh it. Click to remove the skin
2. Inject the sample into the titration cell
3. Take out the sampler and place it on the analytical balance for weighing. The weight displayed on the balance at this time is the weight of the sample
4. Enter the weight of the sample into the instrument and click to start the measurement
5. The measurement is completed, and the instrument displays the measurement results and automatically stores them
The above measurement steps are only applicable to liquids and soluble solids, gases, insoluble solids, side reaction samples, and strong acid and alkali samples. Please feel free to contact us for solutions!

Product Features


Vicometo brandThe WKT-C9 fully automatic Karl Fischer volumetric moisture analyzer has the following characteristics:
1. The instrument status is automatically monitored, and when the measurement conditions cannot be met, the instrument will automatically adjust, allowing you to be a measurement expert without much training
2. The fully automatic electromagnetic three-way valve imported from Japan has a dead volume in the valve body that is only 1/10 of the same domestic product, with silent switching and a switching speed of 0.01 seconds
3. Imported electromagnetic three-way valves solve the problem of traditional three-way valve leakage, capable of withstanding pressures up to 100kPa. Even if the pipeline is blocked, there is no need to worry about three-way valve leakage. Due to its strong pressure resistance, we have increased the pressure inside the pipeline, greatly improving the speed of liquid addition, discharge, and change, and ensuring testing efficiency
4. Large screen display interface, button based operation, multiple shortcut settings, one click operation function, mandatory reminder of operation steps
5. Real time current change reminder function, ultra wide current display, clear trend of the entire measurement process, allowing you to better measure samples
6. Drift value determination function. Adverse environments or special circumstances may cause certain measurement drift to the instrument. The instrument can determine the drift value and you can decide whether to deduct the drift
