Probe cleaning & correctly storing pH probes ensures you get the most accurate readings possible & will maximize the life of a probe. The probe surface is where the instrument takes the reading of the solution or soil/media. If the probe face is dirty or contaminated, the readings may be inaccurate. Much like the windshield of a car, if it's dirty you can't see out! If the probe face is dirty, it cannot read the solution or soil accurately. A tip. If the conductivity reads low, The probe needs cleaning. Ph probes specifically, should be kept wet at all times for optimal performance & life.
