Probe Tips

  • All probes are interchangeable between all Bluelab products
  • All probes carry a 6 month warranty
  • Proper hydration of pH probes is vital to maintain wick
  • All pH probes eventually need to be replaced—they can only house so much reference solution
  • KCl storage solution is required for optimum probe maintenance
  • RO water will reduce probe life
