    Product Details of UHV-660 Automatic Transformer Oil Karl Fischer Analyzer Oil Moisture Tester Coulometric Karl FischerTitrator


    Product Introduction:

    The UHV-660 Electrolytic Oil Moisture Analyzer is designed for the precise determination of trace moisture content in liquids, solids, and gases. It offers outstanding advantages of rapid detection speed and high measurement accuracy. Additionally, the instrument features the capability to measure and display dynamic potential curves, and provides substantial data storage capacity, capable of retaining up to 1,000 test records.


    Product Features

    1. Equipped with a high-performance ARM processor, the instrument ensures stable and rapid operation while delivering excellent anti-interference performance. This contributes to its outstanding advantages in both fast detection speed and high accuracy.

    2. Featuring built-in fault self-diagnosis, the device automatically displays and prints measurement results upon completion. Its dynamic potential curve indication function provides a clear and intuitive visualization of the testing process.

    3. With ample data storage capacity, the instrument can store up to 1,000 test records for convenient review and tracking.

    4. The delay measurement function enhances testing effectiveness, particularly for samples with low moisture content.

    5. The sliding touch control enables intuitive and smooth stirring speed adjustment during operation.

    6. The moisture calculation formula incorporates multiple algorithms, supporting key parameter inputs such as volume and weight for flexible and accurate measurement.

    7. During the testing process, relevant calculation parameters can be modified in real time without affecting ongoing moisture measurement. The system automatically recalculates moisture content based on the updated parameters, offering enhanced convenience and adaptability for users.

    Common troubleshooting
    1. No display
    Check the power cable, power switch, battery (portable instrument with battery).
    2. Measuring electrode open
    Check whether the connection that measuring electrode connect to the instrument plug is good or not, the cable is broken or not.
    3. When electrolysis, electrolysis speed is always zero
    Check whether the connection that electrolytic electrode connect to the instrument plug is good or not, the cable is broken or not.
    4. Water calibration results is small, after sampling the instrument do not detect the sample
    Check the electrolyte is failure or not.
    5. Electrolytic process can not end
    Check the electrolyte is failure or not.
