Determining if a process pH sensor is an analog or digital version
Identification of pH sensor as analog or digital version.
Hach analog pH sensor model numbers will start with 60, PD, or PC. The digital pH sensor model numbers would start with DPD, or DPC. Analog pH sensors can also be connected to a digital controller by using a digital gateway. The appropriate digital gateway model would depend on the type of digital controller it would be connected to.
