  • 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
  • 914 m (3000 ft) transmission distance
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 sensor’s 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.

Comments about GLI Differential pH electrode, 10-ft cable, LCP body:

Hach bought the GLI line years ago, these are either Hach or Old. It is easy to tie the 4-20 mA version (6458P0) to a PLC (built in temp compensation). The one listed here has a thermister, but is 5-wire and requires a meter connected to it in order to create a 4-20 mA signal. On clean water these can last over 5 years (I have been running them more than 15). On inorganic acid / caustic they should last 2 years +, calibrate monthly, they are stable until you need to replace salt bridge or refill fluid. These do have an exposed glass bulb at the bottom, so if you wack it on something your loose you thousand dollar probe. They are very chemically inert, so unless you mechanically damage them they should last years. Of course keep them wet, after all they are a pH probe.

      Comments about GLI Differential pH electrode, 10-ft cable, LCP body:

      The probe works great for a couple of weeks, then stops working completly. We have gone thru several units at our facility, only to have to return it back for a warranty replacement. I give it a half-star, for quality and durrability.
