dedicated to the HI510 Universal Process Controller

 

The HI7640-18 series are galvanic-style oxygen probes designed for use with the Hanna Instruments HI510 Universal Process Controller.

 

The probe is suited for continuous measurement of oxygen dissolved in water. An integral  temperature sensor measures water temperature and adjusts the probe signal over the specified temperature range. The result is reliable dissolved oxygen (DO) concentration or percent saturated measurements.

Suitable for control applications in municipal and industrial wastewater treatment, the probe can be installed directly in-line, immersed in a tank, or in a flow cell installation. 

The galvanic probe functions in the same manner as a battery. The sensing elements consist of silver cathode and zinc anode, with a pretensioned HDPE membrane isolating the cell from the liquid being measured.

 

 

The refillable electrolyte reservoir holds ample electrolyte to support the reaction. Oxygen diffuses through the membrane and is reduced on the surface of the cathode. This reaction generates a signal proportional to the oxygen concentration.

 

  • Galvanic probe with digital processing
  • Simple membrane-cap replacement using pretensioned HDPE membranes
  • Large electrolyte reservoir provides longer service life
  • Rugged, chemically-resistant PVDF (Kynar®) body
  • 3/4” NPT external thread for mounting
  • 3 bar maximum pressure
  • Built-in temperature sensor for measurement and DO compensation
  • Digital probe stores model, firmware, serial number, and calibration information
