Neptune Apex Lite -> Salinity Add-on?

[LIreefguy106]

Greetings fellow hobbyists,

Quick question, I have the Apex Lite. Works great but I want salinity monitoring. Can I purchase just the salinity probe or do I need the PM2 module as well?

Thanks in advance

You will need both the Salinity probe and a PM2 module.

Just an fyi those salinity probes are very touchy any micro bubbles that get into the probe will set the reading off also get extra calibration solution iv had to re calibrate it every 4 months its kinda a pain in the butt and if i could id get my money back and never use the probe.

Thanks for the heads up. Maybe refractometer is the best for now. Sometimes old school is the way to go I guess.
