Part Number: 0059620

Use the pH Sensor Reference Junction Kit to replace junctions on pH sensors (standalone or combination pH/ORP) installed on:

  • TROLL 9500 Multiparameter Sonde
  • smarTROLL Multiparameter Handheld
  • Aqua TROLL 400 Instruments

You know it’s time to replace reference junctions when the sensor fails to calibrate with a reasonable slope and offset, even after replacing the filling solution. Acceptable slope and offset ranges vary by instrument, so refer to your instrument manual for proper ranges.


  • Three replacement junctions
  • 60-mL bottle of reference filling solution
  • Dispenser cap
  • Instruction sheet
