Why does BRS recommend this?
Having the ability to monitor the salinity of your reef tank is a very valuable piece of information. Usually, if something is to go wrong with your tank, you will usually see a change in salinity from temp, to a top off unit being stuck on, if you have a Neptune Apex Controller we highly recommend investing in the PM2 module and salinity probe.
Add the Salinity Module: PM2 to your Apex Neptune System.
- Real-time monitoring of salinity in reef aquarium
- Module has extra Temp Probe port
- I/O Switch Inputs for ATO, feed buttons, leak alarms, etc.
- Probe Sold Separately.
Features of the Neptune Systems Salinity Expansion Module:
- Monitor/Control Conductivity/Salinity and temperature
- 4 Measurement ranges (0-900 uS/cm, 0-9.0 mS/cm, 0-90.0 mS/cm, 0-50 ppt)
- 6 digital inputs for float switches, water on floor sensors, pressure sensors, etc
- Full data logging support in Apex Base module
- Up to 240 AquaBus modules can be added to the Apex system
- Plug and Play - Automatically recognized when installed into the system
- 2 AquaBus connectors for flexible expansion via AquaBus
- Comes with 3′ AquaBus cable
- Galvanic Isolation for accurate and reliable probe readings
- Led Status Indicator
- Upgradeable firmware
- Compatible with all Apex systems

Product Questions
i have the apex package that i bought without this module. doesnt the normall apex already measures the salinity. what is the advantage of this probe. does this show specific gravity ?
Question by: michal makarewicz on Nov 23, 2017, 12:57 PM
The Apex Controller System does include a salinity probe, which measures conductivity, and can be directly converted to salinity. It does not show the specific gravity since all the readings will be in a ppt count. This is the same probe that is included with Apex Controllers that come with a salinity probe.

If I buy this and the salinity probe is that all I need for it to tell me the salinity or do I also have to buy something else for it to work.

Great question! As long as you have a Neptune Apex, those two items will be all you need! Although, you may want to get a few extra salinity calibration solutions. :-)

How does an ATO float switch attach to this module?
I do not see in the photo the inputs to attach the float switches.
I am wanting to use it for both an ATO and salinity monitor.

Great question,
There is not an option to plug in float switches directly to the PM2. If you are looking for float switches you will need the Apex Breakout Box. The breakout box can plug into the I/O port on the PM2 or the apex main module. Feel free to let us know if you have any further questions!

Hi can i hook up two salinity probes or i have to buy 2 modules?
Question by: Jayson on May 5, 2014, 6:29 AM
Hi Jayson,
If you wanted to monitor two salinity probes you would need a module for each probe (so 2 in this situation).

Hi do I need any other probe or equipment to measure the salinity, using that Salinity Module: PM2 - Neptune Systems
Question by: sebastian on Apr 10, 2014, 8:59 AM
Hi Sebastian,
This is the probe module for measuring salinity but make sure to also pick up the actual salinity probe as well!
