Frequently Asked Questions
1. What is the difference between an ORP and a Redox electrode?
In the laboratory, the terms are interchangeable; both measure Oxidation-Reduction Potential, which indicates the tendency of a chemical species to acquire or lose electrons.
2. Why are many redox electrodes made with platinum?
Platinum is a noble metal that provides a chemically inert surface, allowing for electron transfer without the metal itself reacting with the sample, which is essential for accurate ORP measurement.
3. Do I need a specific cable for these electrodes?
Yes, standard electrodes often require specialized cables like the InLab S7 BNC to connect to your meter; digital IDS sensors typically use their own proprietary cable systems.
4. Can I use a pH meter to measure Redox/ORP?
Most modern pH meters have a millivolt (mV) mode that can display ORP readings, provided you have the correct redox-electrode and compatible cable.
