Quick overview
Discontinued
- The HI98121 is a lightweight ergonomically designed tester.
- This tester is designed to float making it ideal for taking readings virtually anywhere.
- With the HI98121 it is possible to monitor both pH and ORP at the same time.
- The HI98121 is commonly used to monitor pH and chlorine for many applications including swimming, food sanitization, plating wastewater treatment, and cooling tower water treatment.
- By definition pH is the measurement of the voltage generated by an electrochemical cell at zero current.
- The potential generated is proportional to the thermodynamic activity of the ion being measured.
- Similar to a pH measurement that quantifies the how acidic or alkaline solutions are, ORP (Oxidation Reduction Potential) measurements quantify the overall state of a solution as having the ability to oxidize or reduce a chemical species.
- Oxidizing and reducing reagents are used to participate in chemical reactions known as a redox reaction.
- An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself.
- It must also have the proper surface characteristics to promote rapid electron exchange, a property known as high exchange current density.
- Two noble metals have proven to work well for this purpose: pure platinum and pure gold are both used in the construction of ORP sensors.
