Pool Line Combo pH/ ORP Tester - HI981214
Description
Additional information
Specifications

Description
HI981214 Pool Line Combo tester is a highly accurate, waterproof pH meter that can also measure ORP and temperature. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. All pH readings are automatically temperature compensated (ATC) for variations in temperature.
HI981214 is ideal for checking the pH and disinfection levels of swimming pools, hot tubs, and spas. The accurate reading of pH is critical to ensure that the chlorine is in predominately the hypochlorous acid form instead of the hypochlorite form, which is less effective at killing bacteria. The ideal pH for a pool is between 7.2 and 7.4.
The ORP portion of the meter is used to monitor the disinfection level of the pool to always be sure that there is enough chlorine present to keep bathers safe from bacteria. The ideal ORP reading is +650 mV. At this voltage any bacteria will be inactivated in a short time. It is important to note that if a stabilizer such as cyanuric acid is used that the stabilizer as a reducing agent will mask the oxidation potential of chlorine. ORP should not be used when chlorine is introduced as solid puck since it is likely that it will have stabilizers as well.
Replaceable ORP Electrode Cartridge
The HI981214 tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!
Platinum ORP Electrode
The ORP probe uses a platinum tip sensor, which is ideal for oxidation reactions such as adding chlorine for disinfection.
Features at-a-glance:
3 sensors in a single meter
- pH electrode with extractable junction
- ORP electrode
- Temperature probe for pH temperature compensated measurements

pH/ORP/Temperature Combo Tester - HI98121
Description
Additional information
Specifications
Download
Description
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.
Features at-a-glance:
- Waterproof
- Automatic Temperature Compensation
- HOLD feature
- Simple to use
- Economical
Additional information
The HI98121 is a waterproof pH, ORP and temperature meter. The housing of this tester has been completely sealed against humidity and is designed to float. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement. When the cloth junction becomes clogged and response time is sluggish, simply pull out 3 mm (1/8”) to clear the clogging which will improve response time and stability. The exposed stainless steel temperature sensor on these models facilitates faster and more accurate temperature measurement.

Oxidizing and reducing reagents are used to participate in chemical reactions known as a redox reaction.

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. Both are commonly used in the construction of ORP probes.
The platinum sensor is often preferred because it is mechanically simpler to produce. Platinum can be welded to glass and also has a similiar thermal expansion coefficient. Sensors made of gold cannot be welded to the glass and are often placed in plastic supports applied to the glass or plastic tube by means of tiny elastomeric bungs.
Many industries rely upon ORP measurements including swimming pools, food processing, boilers and cooling towers, and plating. The measurement of ORP helps the user monitor the effectiveness of disinfecting compounds including chlorine and ozone. ORP is also used to monitor redox reactions including the use of bisulfite in the reduction of hexavalent chromium to trivalent chromium in plating wastewater.
