The instrument is only as accurate as the probe is clean. Accurate readings simplify crop management and provide improved growth.
 
Probe cleaning and correctly storing pH probes ensures you get the most accurate readings possible and 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.
 
pH probes specifically, should be kept wet at all times for optimal performance and life.
