Neptune Systems Lab Grade Conductivity/Salinity Probe

Start Measuring Salinity in Your Reef

Replace an old probe or add salinity monitoring to your Apex Aquarium Controller. Maintaining consistent salinity in your aquarium is key to the well-being of every organism inside it. Often, we're so busy that we overlook changes in the salinity of our reef aquarium until problems arise. With real-time salinity monitoring, you can be alerted to potential issues and do something about it.

No Salinity Port? No Problem!

If your Apex doesn't have a salinity probe port, you can easily add one with the separately available PM2 Salinity Module. The PM2 Features a salinity probe port, temperature probe port, and an I/O port.
