pH/Conductivity Meter – Orion StarTM A325

Examples of use:

  • Measurements of the pH of aqueous electrolytes, e.g. in pickling or plating baths
  • Measurements of the conductivity of aqueous electrolyte solutions
  • Process and quality control


Device configuration:

  • Portable multi-parameter meter
  • IP67-rated waterproof
  • 2-channel system for simultaneous measurement of both pH and conductivity
    • Channel 1: pH, mV, relative mV, ORP
    • Channel 2: conductivity, TDS, salinity, resistivity
  • ROSS UltraTM TriodeTM electrode for pH measurement in concentrated solutions: pH range of 0 to 14 (precision of 0.01)
  • DuraProbeTM 4-electrode conductivity cell: measurement range of 1 µS/cm to 200 mS/cm
  • Integrated display of measuring conditions: temperature, stability
  • Up to 5 point pH calibration with automatic recognition for USA/NIST and DIN buffers
  • Automatic and manual conductivity calibration
