Hanna presents a series of combination pH and ORP electrodes, including more than 300 models, incorporating over 20 years of electrode manufacturing experience.
The most advanced feature of this series is the electrode shape with a flat tip, virtually eliminating deposits that can foul the electrode, significantly reducing necessary maintenance. This characteristic makes flat tip electrodes ideal for continuous in-line monitoring and for solutions containing aggressive chemicals.

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 the wide 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.
In many industrial applications, especially in plating baths, grounding loop current is a very common problem.
When a traditional electrode/controller system is used with the electrode reference connected both to the electrode and to the instrument, a current flow occurs through the reference half cell, causing fluctuations in reading and serious damage to the Ag/AgCl element. The potential matching pin shields the reference from external electrical fields. Shown above, the matching pin allows the measurement to stabilize and ensures effective process regulation. In order to function properly, the matching pin has to be continuously immersed in the measured solution and for this reason is placed near the electrode junction.
These electrodes have been designed with ¾” external thread on both ends for easy installation. HANNA instruments® also provides a series of probe holders for in-line, tank or by-pass installations for these electrodes, as shown below.
The pH electrodes with built-in 3-wire Pt100 or Pt1000 temperature sensor allow for the temperature compensation of pH readings as well as temperature measurements.
Electrodes are wired for direct connection to a transmitter or process controller, or with the standard BNC connector.
Models with a built-in amplifier are necessary for long distance measurements, where it is not possible to install a transmitter. The internal amplifier can be powered directly from select Hanna process controllers or a power source that supplies the appropriate voltage.
Non-amplified electrodes are provided with a 5, 10 or 15 m cable (16’, 33’ or 49’)
The PVDF body used for the Flat Tip Series withstands high pressure and high temperature applications, and guarantees a high chemical and mechanical resistance. These characteristics makes the PVDF material the most recommended for many industrial applications. PVDF is also non-toxic and compatible with food applications.
