BNC Replacement pH or ORP Probe

✅ Keep the meter working. A replacement electrode refreshes the sensing part of a compatible meter without replacing the display.

✅ Choose the measurement. pH and ORP need different probes, so match the electrode to the reading you take.

✅ Give the sample room. The approximately 70 cm lead separates the probe from the meter during measurement.

✅ Plan calibration. Calibrate and condition the probe as instructed before you rely on its readings.
