Neptune Apex Conductivity Probe (salinity)

Track salinity levels with precision using this Neptune Apex conductivity probe, designed to monitor parts per thousand (ppt) in real time. Consistent salinity is essential for the health of your marine livestock, yet fluctuations often go unnoticed until problems arise. This probe delivers continuous feedback on evaporation rates and salt concentration changes, helping you stay ahead of parameter drift. Compatible with PM2, A2, and A3 Apex Series controllers via any available salinity port. Ideal for aquarists who want reliable, automated monitoring without the guesswork.
