Probe cleaning, hydrating and correctly storing pH probes ensures you get the most accurate readings possible and will maximize the life of the pH probe. Ph instruments require calibration once a month and should be cleaned prior to calibration. The handy pH Probe Care Kit has everything you need to maintain your Bluelab pH Meters, Monitors or Pens.

Product description

The instrument is only as accurate as the probe is clean. Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller. The probe surface is where the instrument takes the reading of the solution. If the probe face is dirty or contaminated, then the reading will be inaccurate. Accurate readings simplify crop management and provide improved growth.

Care, hydration and calibration – in one kit

Maintaining your Bluelab pH and conductivity probes

To ensure ongoing accuracy and longevity, we recommend that you maintain your Bluelab probes on a regular basis. 

While no calibration is required for conductivity and temperature, you will need to calibrate your pH probe. Your Probe Care Kit contains sachets of pH 4.0, pH 7.0 and KCl solutions for calibrating and storing your pH probes, as well as 2.77 EC standard solution for testing your conductivity probe after cleaning. This kit also includes probe cleaner and cleaning instruments. 

You’ll have everything you need to clean, calibrate and hydrate your probes – in one compact and affordable kit.  

Improve product longevity with regular calibration 

How to calibrate your Bluelab pH products

If you want to improve your Bluelab pH product’s accuracy and longevity, you’ll need to get into the habit of regular cleaning and calibration.  

Luckily, the easy-to-follow calibration process is the same for all Bluelab pH probes and pens.  

After cleaning your pH probe, you’ll need to calibrate it with pH calibration solutions at two reference standards - 4.0 and 7.0 pH. Once calibrated, you can start measuring pH again immediately. You’ll need to recalibrate whenever you clean your pH probe and when your meter alerts you that a calibration is needed.
