Standard Grade pH Probe - PRBPHS - Neptune Systems

Standard Grade PH Probes tend to last longer, give more accurate results, stay calibrated longer, need replaced less frequently.

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

This product will not function stand-alone; it requires a Neptune Systems Apex Controller.
