For use with Neptune System Apex
Buy this probe if you are:
- You measure ORP in your aquarium with an Apex System or a PM1 module
- replacing a worn out ORP probe (we recommend you replace your Lab Grade ORP probe every 24 months).
- adding another tank to your system, want to measure ORP in it, 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
