Product details
Hengteya brandOrganic solvent Karl Fischer moisture detectorThe Karl Fischer coulometric titration method, also known as Karl Fischer coulometric titration or Karl Fischer coulometric titration, is an internationally recognized method for detecting trace amounts of moisture in samples. The testing accuracy of 1ppm can meet the high requirements of various factories and laboratories for moisture accuracy. It has been widely used in departments such as power, petroleum, chemical, pharmaceutical, energy, scientific research, and education, and is a fully automatic moisture analyzer.
Hengteya brand organic solvent Karl Fischer moisture detectorAdopting a color LCD touch screen, mobile navigation, full Chinese menu, touch operation, clear at a glance, easy to operate. The instrument adopts dual CPUs, greatly improving the computational efficiency of testing. It is equipped with a large capacity data storage program for easy access to historical testing data, and a built-in micro printer can print out data at any time. Hengteya's instrument has multiple built-in calculation formulas. After selecting the appropriate formula for testing, it directly displays the percentage or ppm of moisture content. The instrument comes standard with dual platinum electrodes, which have high sensitivity and more accurate test results. The instrument has good sealing performance, avoiding the situation where the instrument cannot reach the endpoint due to high humidity in the external environment. The blank current microprocessor of the instrument can also eliminate the influence of the closed environment, allowing the reagent to quickly reach equilibrium. It is a multifunctional intelligent integrated instrument.

3. Reagent equilibrium. Inject an appropriate amount of pure water into a 50 microliter sampler to neutralize any excess water in the reagent;
4. Instrument calibration. Using a 0.5ul sampler to extract 0.1ul of pure water for injection, the displayed result should be "100 ± 10ug (excluding injection error)". If the displayed result is within the error range, sample measurement can be performed.
5. Sample determination. After pressing the start button to inject the sample, the instrument will automatically perform the test. After the test is completed, a beep alarm will sound and the display screen will indicate "Test completed".
Hengteya brandOrganic solvent Karl Fischer moisture detectorprecautions：
1、 Cannot display normally
Please check if the power connection wire, fuse, and power switch of the instrument are functioning properly.
2、 The instrument displays iodine
1. Evaluate whether the reagent is over iodine. If so, use a 0.5 microliter sampler to extract 0.2-0.4 microliters of water and inject it. Do not use an injector of 50 microliters or larger for injection.
2. Check whether the platinum wire at the bottom of the measuring electrode is connected together, causing a short circuit.
3、 The instrument shows an open circuit
Check if the measuring electrode is in good contact and re insert it firmly. Check if the connecting wire is broken.
4、 Open electrolysis without counting
Check if the electrolytic electrode is in good contact, unplug and plug it again, and check if the connecting wire is broken.
5、 Electrolysis does not end
Check if the reagent has expired.
