Frequently Asked Questions
Does the instrument have self-diagnostic functionality?
Yes, the pH meter includes self-diagnosis capabilities. During calibration and maintenance, it automatically diagnoses the PH/ORP sensor. If improper operation or poor sensor characteristics are detected, the screen displays an image alert and advises users to re-maintain or replace the sensor.
What are the special advantages of this pH instrument?
The instrument features patented temperature compensation technology that not only compensates for sample temperature via connected sensors but also self-checks the instrument's working temperature in real-time. This compensates for hardware changes caused by temperature drift, ensuring more accurate test results.
