A Worldwide Leader in Electrode Manufacturing
Since the beginning of the 1990’s Hanna has been a leader in the research & development of pH electrode technology. The HI1000 series of digital pH probes represent the continual evolution of the technology. The HI1000 series perform all measurements within the probe and then transfer the data digitally to a process meter with a digital probe input.
The use of digital sensors allows for a process meter to be updated measuring a different parameter without changing controllers. This technology allows for a facility that has multiple control points to only have to maintain a single version of a controller.
The other advantage is that the digital transmission of measurement data is immune to electrical noise generated by motors, pumps, and humid environments. The digital signal can be transmitted over very long distances. This cannot be done with a standard analog probe unless it is amplified or a transmitter is used. The HI1000 of digital probes are available with cable lengths up to 50 meters.
All Hanna industrial digital pH electrodes are combination type, i.e. the reference half cell and the measurement half cell are assembled in the same body. All of the probes are made with a chemically resistant PVDF body and have a pt100 temperature sensor for automatic temperature compensation.
In many industrial applications there is a potential for a ground loop. This can happen when the ground of the process is different than the ground of a controller/transmitter.
When a traditional electrode/controller system is used, the electrode reference is connected from the electrode to the instrument and current can flow 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 for easy installation for in-line applications. HANNA instruments® also provides a series of probe holders for submersion tank installations.
All HI1000 series of digital pH electrodes have a built-in 3-wire Pt100 temperature sensor that allows for the temperature compensation of pH readings as well as temperature measurements.
Electrodes are wired for direct connection to the HI510 Universal Process Controller.
HI1000 digital pH probes are available with a 5, 10, 15, 25, or 50 m of cable.
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 make the PVDF material the most recommended for many industrial applications.
