The instrument is only as accurate as the probe is clean. Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor, or controller. The probe surface is where the instrument takes the reading of the solution or soil/media. If the probe face is dirty or contaminated, then the reading will be inaccurate. Accurate readings simplify crop management and provide improved growth.
