pH / ORP Sensors

Differential Probes

There are hundreds of pH and ORP 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.

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.
