PH/ORP gauges not only fulfill the remote management technology WIFI but also has a temperature detection and temperature compensation function, supporting pH electrodes with temperature to measure temperature changes in aqueous solutions. It is a patented temperature drift compensation technology, which makes the instrument more stable and accurate in all kinds of environments.
The PH/ORP gauges use salt-bridged primary battery electrodes (PH electrodes) to detect changes in the concentration of hydrogen ions in the solution, which affect the electrode level. It is usually made of glass and commonly known as PH glass electrode measurement. Mathematic defines pH as a commonly used congenital negative value for the concentration of hydrogen ions, i.e. pH=-lg[H⁺]

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.
