ORP-169E Digital Redox Meter

Add numerical redox readings to your water checks with a tester you can carry between samples. The ORP-169E displays oxidation-reduction potential in millivolts in a compact pen-style body.

✅ Keep a numerical reference for later checks - The digital mV reading lets you note and compare ORP values over time.

✅ Take the measurement to the sample - The portable battery-powered format suits checks away from a fixed bench instrument.

Follow Redox Changes With a Clear Reading

ORP describes oxidation-reduction potential, a different parameter from pH. Use the reading as part of the water-monitoring question you are investigating, rather than treating one number as a complete description of water quality.

For comparisons, note each reading with the date and sample conditions, following the meter's electrode-care instructions. A consistent manual record makes it easier to return to the same water-checking question later.
