Keep your meters and testing equipment running effectively and accurately by grabbing a Bluelab Replacement pH Probe. This replacement works with the Bluelab Combo and pH meters, along with the Bluelab Guardian Meter. Eventually, your original probes will wear out through normal use, and start to give inaccurate readings toward the end of their life. At this point, you'll need to replace the probe to keep the meter running efficiently.
With proper care of your probe, such as keeping the tip wet and monthly cleaning/calibration, you can get a long, fruitful life from it. However, nothing lasts forever. Keeping a Bluelab Replacement pH Probe on hand will ensure you don't have any downtime with nutrient testing.

Bluelab Replacement pH Probe Questions & Answers
Why do we need to clean the probes on Bluelab instruments?
A clean probe is an accurate probe!
Cleaning is the most important piece of maintenance required on any Bluelab instrument. The probe comes into contact with the solution and relay the reading back to the instrument for it to be displayed. The probe surface is susceptible to being contaminated or being covered in a greasy film that inhibits an exact reading. There are no shortcuts to cleaning the probes. It is already a very simple procedure and it will also ensure your instrument measures it right every time.
Are any of Bluelab’s pH probes suitable for measuring the pH of pure water?
No, not at this stage.
Why do I need to use KCl vs tap water or pure water to hydrate and/or store my pH pen or probe in?
Bluelab pH Probe KCl Storage Solution contains the same mix as the KCl reference found in Bluelab pH probes or pens. When you hydrate or store the pH probe/pen in KCl storage solution, you’re re-vitalising the KCl reference solution inside the pH probe.
If you use tap water to hydrate or store the pH probe/pen, it can change or weaken the reference inside the probe. Simply put, tap water is not as effective as KCl.
De-ionized, RO (Reverse Osmosis), or Distilled water should NEVER be used to store or hydrate the pH probe or pen. Pure water changes the chemistry in the reference, causing the pH probe/pen to die.
