Product Q&A

Bluelab Soil pH Pen Questions & Answers

There is a salt crust forming on the pH probe, why?

The pH pen, soil pH pen, pH probe and soil pH probe contain KCl storage solution inside the storage cap. KCl storage solution contains saline (salt). It is possible that a small amount of this solution may leak out and once this liquid evaporates a salt crust will form. This salt crust is normal and there is no reason for concern.

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.
