    FAQ
    Q1. Does the instrument have a self-diagnostic function and how does it prompt?

    A: The pH meter has self-diagnosis function.When the instrument is in calibration and maintenance,it can diagnose the PH/ORP sensor,if there is improper operation or poor PH/ORP sensor characteristics, the screen makes an image display and advises the user to re-maintain or replace the sensor.


    Q2. What are the special advantages of the pH instruments?
    A: The instrument can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
