Everything you need to clean, hydrate and calibrate pH probes.
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.
You can re-stock your probe care kit with bottles of Bluelab Solutions.

When should I hydrate my pH pen or pH probe?
The Bluelab pH Pen needs to be "hydrated" for 24 hours before the first use, and each month after cleaning and before calibrating. Each week, you'll need to add 3 to 5 drops of KCl storage solution to the wetting seal (round hole) of the storage cap.
Bluelab Soil pH Pens, pH Probes or Soil pH Probes should be hydrated each month after cleaning and before calibrating.
Each month think: Clean, hydrate, calibrate. This will optimize the performance and life of your pH probe or pen.
If the pH pen or pH probe has accidentally been allowed to dry out, hydrate for 24 hours in KCl storage solution.
