Bluelab Probe Care Kit - pH & Conductivity

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.

A tip: if the conductivity reads low, the probe needs cleaning. pH probes specifically, should be kept wet at all times for optimal performance and life.
