6528 pH double junction probe

he 6528 pH probe consists of a pH sensor with a voltage output that varies proportionately to the hydrogen ion activity between a reference electrode and an electrode immersed in an alkaline (basic) or acidic solution.

  • Product Name:pH double junction probe
  • Item No.:6528
  • Manufacturers:Unidata

pH double junction probe 6528 have a rugged design and utilises a double junction reference system to minimise the effects of contamination due to clogged pores or ingress of sample. Probe is designed as a low power instrument and includes built-in conditioning electronics for direct connection to a data logger

The 6528 pH probe consists of a pH sensor with a voltage output that varies proportionately to the hydrogen ion activity between a reference electrode and an electrode immersed in an alkaline (basic) or acidic solution. These advanced electrodes feature proven flat tip technology which virtually eliminates deposits that can foul the electrode, significantly reducing necessary maintenance.

Each electrode has a built-in potential matching pin. With this feature, electrode fouling due to ground loop current through the reference of the sensor is a thing of the past. These electrodes have been engineered with a replaceable battery to power the amplifier. This feature adds life to the electrode and aids in troubleshooting. With this feature, electrode fouling due to ground loop
