Bluelab pH Probe Cleaning & Calibration Kit
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. Specifications Weight: 5.0 lbs.

A: Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption.
