Welcome to Swap Engineering
No matter what application you’re using it for, a pH sensor will allow you to keep pH levels at a level most ideal for the process. This could be anywhere from strong acids to caustics. There are many different types of pH sensors that you can obtain for your application in the course of liquid measurement; these could include combination pH sensors, laboratory pH sensors, process pH sensors, and differential pH sensors.
Different pH sensors are built for different applications, which you should fully understand before purchasing one of these sensors.
