Unsurpassed accuracy with differential measurement technique Three electrodes instead of the normal two in conventional pH sensors Greater reliability resulting in less downtime and maintenance Replaceable salt bridge/protector Encapsulated electronics and preamp Versatile body styles and mounting hardware including retrofit Differential Electrode measurement technique uses three electrodes instead of the two normally used in conventional pH sensors. Process and reference electrodes measure the pH differentially with respect to a third ground electrode. The end result is unsurpassed measurement accuracy, reduced reference junction potential, and elimination of sensor ground loops. These sensors provide greater reliability, resulting in less downtime and maintenance. The unique, replaceable salt bridge holds an extraordinary volume of buffer to extend the working life of the sensor by protecting the reference electrode from harsh process conditions. The salt bridge simply threads onto the end of the sensor if replacement is needed. Encapsulated design of the preamp protects the sensors built-in preamp from moisture and humidity, ensuring reliable sensor operation. The preamp in the pH sensor produces a strong signal, enabling the sensor to be located up to 914 m (3000 ft.) from the analyzer. This listing is for Each.

Hach - PD1R1 - Hach pHD Online Process pH Sensor - pH Sensor for Clean Water

  • Item #: 9599080
  • MFR SKU: PD1R1
Technical Specs
  • Exceptional Process pH Sensor Performance with the Differential Electrode pHD Measurement Technique
  • This field-proven technique uses three electrodes instead of the two normally used in conventional pH sensors. Process and reference electrodes measure the pH differentially with respect to a third ground electrode. The end result is unsurpassed measurement accuracy , reduced reference junction potential , and elimination of sensor ground loops. These process pH sensors provide greater reliability , resulting in less downtime and maintenance. Lower Maintenance Needs with the Double Junction Salt Bridge
  • The double junction salt bridge creates a barrier to contamination which minimizes the dilution of the internal standard cell solution. The result is lower maintenance needs and a longer time period between calibrations. Extended Working Life with the Replaceable Salt Bridge/Protector
  • The unique , replaceable salt bridge holds an extraordinary volume of buffer to extend the working life of the sensor by protecting the reference electrode from harsh process conditions. The salt bridge simply threads onto the end of the sensor if replacement is needed. Reliability with Built-in Encapsulated Preamp
  • Encapsulated construction protects the sensor\xe2\x80\x99s built-in preamp from moisture and humidity , ensuring reliable sensor operation. The preamp in the pHD analog sensor produces a strong signal , enabling the sensor to be located up to 1000 m (3280 ft.) from the analyzer. Patented Technology
