Calibrate it regularly with Hanna calibration solutions, and keep the electrode clean with cleaning solution. Our pH and EC meters guide explains what to aim for.
Questions
How is a monitor different from a pen?
A pen takes a reading when you dip it. The monitor reads continuously, so you can see the pH, EC and temperature of the solution at a glance at any time.
Does it need calibrating?
Yes, like any pH and EC meter. Calibration is simple and keeps the readings accurate.
