The instrument is only as accurate as the probe is clean!
Bluelab cleaning kits
Probe cleaning is one of the most important parts of owning and operating any Bluelab
meter, monitor or controller. If the probe is contaminated (dirty) it affects the accuracy of
the reading displayed.
The probe surface is where the instrument takes the reading of the solution. The information is sent back
from the probe to the electronic brain of the instrument.
A calculation is then done in the instrument's brain or micro computer and a reading is then displayed.
If the information sent back from the probe is inaccurate due to probe surface contamination then the
reading will be inaccurate. Cleaning the probes is a very easy task and will prolong the life of the probes.
