BNC Replacement pH or ORP Probe

Replace a compatible meter's electrode with the probe for the measurement you need. This range offers separate pH and ORP options with a BNC connector.

✅ Keep an existing compatible meter in use - A replacement electrode refreshes the sensing part.

✅ Choose the measurement type - pH and oxidation-reduction potential require different probes.

✅ Place the probe away from the meter - An approximately 70 cm lead gives some separation between sample and display.

pH and ORP Probes Are Not Interchangeable

Choose E201 or E201C for the stated pH range of 0-14, or 501-3 for the stated ORP range of 0-1500 mV. Confirm that the meter supports the actual electrode type as well as the BNC connection.

Calibrate and condition the probe according to its instructions before relying on readings. Store the glass electrode using the correct solution and care procedure; the meter is not included.
