In-SituAT-phORP-ISE-KitOverview

Reference Junction Kit (pH/ORP and ISE Sensors) (P/N: 0078990)
Manufactured by:  In-Situ

Includes:

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

Use the pH Sensor Reference Junction Kit to replace junctions on combination pH/ORP sensors or Ion Specific Sensors (Ammonium, Nitrate, or Chloride) installed on:

  • Aqua TROLL 500 Multiparameter Sonde
  • Aqua TROLL 600 Multiparameter Sonde

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.
