Innovative reference system prevents precipitation of solution components at reference element from 0° to 100°C. Internal electrolyte has minimal temperature coefficient.

  • Electrodes are predictable, reliable and quick to respond at any temperature
  • Cycled between samples at 25° and 80°C, reach reproducible pH in 30 seconds
  • Read pH in <20 seconds, correct to ±0.02pH; pH value stays constant at any temperature
  • Read pH consistently at elevated temperatures, without premature loss in performance
  • Choose from glass body double-junction model, or from glass and epoxy body models with accuFlow™ flushable junction
