Online turbidity analyzer manufacturer 2025: pH Calibration – Use Buffer Solutions: These are reference liquids with known pH values, typically pH 4.01, 7.00, and 10.01. Rinse the Electrode with distilled water, then dip it into the pH 7.00 solution. Wait for the reading to stabilize, then press “Calibrate” or “Enter”. Repeat with pH 4.01 and/or 10.01 for two- or three-point calibration. Always perform multi-point calibration for high-accuracy environments like labs or industrial water monitoring. Conductivity Calibration – Use a standard conductivity solution (e.g., 1413 µS/cm). Rinse the probe, dip it in the solution, and wait for stabilization. Adjust the reading …
