Neptune System - pH Probe Lab Grade

pH Probe – Lab Grade

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
