Neptune Systems Apex Lite Controller Package:

-Package includes: Apex Lite Base Unit, Apex Display Module, Temperature Probe, and Energy Bar 8 Module.

And add on:
- Conductivity Probe
- pH Probe - Lab Grade
- ORP Probe - Lab Grade

Any other suggestion for add-ons

The standard package and unit won't allow you to measure salinity. To monitor salinity, you need to buy the probe ($130 ) and the PM2 module ($92)

Also The Apex base unit supports 3 probes. (Temp, pH, and pH/ORP). The Apex. Lite only supports 2 (Temp, pH)
