Description
The double-junction pH probe is Neptune’s long-haul option: the reference junction resists fouling, so it holds calibration for months where cheap probes drift in weeks. Stable pH data is the backbone of kalk dosing, CO2 scrubbing, and alk stability.

Shipping & Returns
- Equipment and dry goods ship at their own rate. Free shipping at $349 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $10 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
- Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
