Nutrient Probe Cleaning Kit
Nutrient Probe Cleaning Kit
List Price: $21.50
Our Price: $18.50
Savings: $3.00

The Probe on Bluelab meter, monitor, Truncheon or controller must be kept clean. If the probe is contaminated or dirty, it affects the accuracy. The probe surface is where the instrument takes the reading of the solution and the information is sent back from the probe to the electronic brain of the instrument. Cleaning is a very easy task and it prolongs the life of the truncheon.

This is the Nutrient Probe Cleaning Kit - not for their pH meters.
