A Worldwide Leader in Electrode Manufacturing
Since the beginning of the 1990’s Hanna has been a leader in the research & development of pH and ORP electrodes. Today, Hanna is proud to
present the latest family of industrial electrodes, the Flat Tip Series, which completes thewide range of Hanna probes for any process application.
All Hanna industrial pH and ORP electrodes are combination type, i.e. the reference half cell and the measurement half cell are assembled in the
same body.
Reference Half Cell
The reference half cell provides a known and stable reference potential. During the normal
electrode life span, this potential can vary, possibly signaling the end of the electrode’s life.
• The main causes of reference potential variation are:
·
·
Electrolyte contamination
·
·
Dilution
·
·
Electrochemical reaction
·
·
Junction clogging
As a result of many years of experience and electrode testing in industrial applications,
Hanna has found the solutions for all these challenges.
