Differential pH and ORP Probes
There are hundreds of pH and ORP (redox) probes in the marketplace. Only a few use differential technology. And only one is the legendary Aquametrix probe. For three decades the Aquametrix differential probes have set the standard for durability, longevity and precision. These sensors may cost more up front but, in very aggressive processes, they will end up saving money over the years.
Every model comes as either a pH ("P") probe or ORP ("R") probe. All but one class of sensors are meant to be used with the Shark controller or Shark TX transmitter. The P/R-65 series of differential probes provide direct 4-20 mA output for a PLC or the AquaMetrix 2300 controller.

P/R60C-6 Variable Insertion, Differential pH/ORP Sensors
This unique pH probe mounts in a standard 1 1/4” NPT tee, or in a tank, through a specially designed CPVC compression fitting. The probe enters straight into the fitting eliminating twisting of the cable; the pipe size is only 1 1/4” NPT and the insertion length is variable - between 7/8” and 5”.

P/R60C-5 pH/ORP Probe
The P60C-5 pH is the newest addition to the Aquametrix differential probe family. It's 1" NPT size allows it fit into tight spaces where the P60C-8 might be unwieldy. The flat face version (pictured above) is ideal for processes that foul probes with protruding electrodes.

Combination Probes
For applications that involve clean water and that do not need years of service from a probe a combination probe is an economic alternative. These probes are sometimes called for when the process is so aggressive that no probe lasts longer than a year. The 500 sereies probes come in a fixed insertion or a variable insertion form factor. They can be ordered with automatic temperature compensation or a pre-amp to allow transmission over distances greater than 10 feet. Models are also available that contain an HF resistant antimony electrode and a hardened glass electrode.

P/R575 Fixed Insertion, Combination Style pH/ORP Sensors
These combination probes provide an economical alternative to higher cost models. The durable materials wetted by the process provide excellent chemical resistance. The convertible design of these probes allows them to be used in flowthrough and submersion applications thus minimizing inventory requirements. The probes are offered with or without temperature compensation.
