Application of 8651 AZ pH and ORP Detector:
The portable 8651 AZ pH and ORP Meter can measure the pH and oxidation reduction potential value, which had been widely operation in the Water Quality Testing applications.
The pH sensor electrode should connect to BNC port on the top of the 8651 AZ pH and ORP Meter, and its temperature sensor could be inserted to the phone jack port next to BNC.
