Lab Grade pH Probe

Lab Grade pH Probe

Regular price $ 69.95

Replace your pH probe or add another for another tank, calcium reactor, etc.

Buy this probe if you are:

  • Buying an Apex Lite (it does not include a pH probe)
  • Replacing a worn out pH probe (we recommend you replace your pH probe every 18 months)
  • Adding another tank to your system and purchased a PM1 to do so
  • Want to have a back-up probe on hand

Lab Grade Probes tend to last longer, give more accurate results, stay calibrated longer, and need replaced less frequently
