Bluelab - Cleaning and Calibrating

Regular cleaning and calibration of your pH pen or probe are vital to ensure accurate and reliable pH readings. Over time, residues and contaminants can build up on the probe, affecting its sensitivity and accuracy. Cleaning removes these contaminants, while calibration adjusts the probe to a known standard, correcting any drift in its readings. This routine maintenance is essential for consistent performance, whether you're monitoring water quality, soil pH, or other applications requiring precise pH measurement.
