pH/ORP/Temperature Combo Tester - HI98121
The HI98121 is a waterproof pH, ORP, and temperature meter. The housing of this tester has been completely sealed against moisture and is designed to float. The replacement of the electrode with the stainless steel round connector means there are no pins to bend or break during replacement. When the fiber junction becomes clogged and the response time is slow, simply pull 3 mm (1/8") to clear the blockage, which will improve response time and stability. The exposed stainless steel temperature sensor in these models facilitates faster and more accurate temperature measurement.

The HI98121 is a lightweight tester with an ergonomic design. 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 simultaneously. The HI98121 is frequently used to monitor pH and chlorine for many applications, such as swimming, food disinfection, plating, wastewater treatment, water treatment, and cooling towers.
 
By definition, pH is the measure of the tension generated by an electrochemical cell at zero current. The generated potential is proportional to the thermodynamic activity of the ion being measured.
 
Similar to a pH measurement that quantifies the form of acidic or alkaline solutions, (oxidation-reduction potential) ORP 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.
 
A redox sensor must be chemically inert; it cannot be oxidized or reduced itself. It must also have the appropriate surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two noble metals have been shown to work well for this purpose: pure platinum and pure gold are used in the construction of ORP sensors.
