Controlling the pH level of a solution is usually a tedious task. Adding an acid or base to the solution will change the pH, but manually monitoring the levels and adding the correct amount isn’t fun.

The pH and ORP differential probes provide accurate measurements under conditions that often render conventional pH probes inoperable. The probes feature an integral two-wire, 4 to 20-mA transmitter; ...

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...

An ORP sensor, very similar to one for pH, reports the ORP value in millivolts (mV). A positive voltage means that the system is capable of attracting electrons, thus indicative of an oxidizing ...
