EN Coax Connectors and Components

pH
pH 21
Connectors for pH-electrodes (acc. DIN 19263 an DIN 19264)
have increased in importance as have pH-measurements
themselves. The close control of pH is of primary importance
in the medical industry as well as in the electroplating, textile,
pharmaceutical, and food industries.
Steckverbindungen für pH-Elektroden (nach DIN 19263 und
DIN 19264) haben, wie die pH-Messungen selbst, in ihrer
Bedeutung zugenommen. Im Labor- und Industriebereich ist
die exakte Steuerung des pH-Wertes von enomer Wichtigkeit,
insbesondere in der Gesundheits- und Galvanotechnik, der
Textil-, Pharma- und Lebensmittelindustrie.
