Neptune Systems

The first expansion module, the PM1, with a pH or ORP, temperature, and 6 digital inputs.

4 in 1 goodness with this module!

The PM1 probe module is just what you need if you want to monitor pH or ORP in your tank. And, there is an added bonus, you get an extra temperature port as well as six I/O switch inputs for use on ATO, feed buttons, leak alarms or whatever else you may come up with. (I/O Break Out Box required).

This module is perfect for someone that wants to add an additional pH or ORP port to their Apex System.

Great uses for the extra ports

If this is an additional pH port, it could be used for another tank or for control of the CO2 solenoid on your calcium reactor.

If you choose to use it for ORP, you could have the Apex use that ORP value to turn on and off an ozone generator.

Of course, you could set up audible or email alerts too if these values should fall out of range.

Extra Temperature port

Having an extra temperature port and probe is always useful. Some people like to put one probe in the display tank and one in the sump just for redundancy. That way, should your return pump go out, you would be monitoring the display tank and would see the temperature falling and know something was not right.

Want to monitor an additional tank?

With the PM1 you can easily use your existing Apex to monitor additional tanks simply buy adding this module. Then, just buy our pH and Temperature probes and you’ll be all set!

Six I/O Switch Ports

Purchase the optional I/O Breakout Box and you can monitor the off/on state of six I/O signals. This is useful if you want to set up an ATO (Auto Top Off), a feed button, or even a sump door alarm or light switch.

Features:

  • Monitor/Control pH or ORP, and temperature.
  • 6 digital inputs for float switches, water on floor sensors, pressure sensors, etc. (I/O Break Out Box required)
  • Full datalogging support in Apex Base module.

Very happy

I already have an established apex system on my main system. For Christmas my daughter begged me for her own tank in her room. So, Santa brought her a innovative marine Nuvo 8 (bought here). It is setup as a fish only saltwater tank with live rock. I couldn't see myself going backwards with analog or digital timers and I wasn't a fan of having another console with a full apex deployment. So, pm1 and a little snaking of a 100ft apex cable through my attic and presto. Full monitoring and control of my nano. Yeah I know it is overkill, but isn't most of the stuff we do with this hobby?

Love it

I have been having issues with several corals in my reef tank for months now. They were only happy occasionally and I could not figure out exactly why. Come to find out I was unable to distinguish the colors on my pH test kit. After installing the PM1 With a pH probe it was obvious that I have chronic low pH and that was causing my corals to not to thrive like they are now. After only 5 days it's amazing the difference now that I am keeping my PH where it should be. NOTE 2 other older guys: our eyes ain't what they used to be! I love this product and I wish I would have bought it months ago.

Works as advertised

Great product... Documentation was good, but it should have just told you to use the web interface to calibrate it...Don't forget to buy the actual probe you want to monitor... Customer Service did a nice job getting me squared away, after I forgot the probe.... :)

Bought PM1 for my APEX Jr.

I recently added this unit to my Apex Jr. (I'm loving the Apex Jr. and I purchased it without the display). I was a bit concerned about the PM1 working with my setup when I first read the directions. It says in the directions that the PM1 cannot activate a pH probe in the web interface, which is all I have! THAT IS NOT TRUE! I wrote Neptune systems and they assured me it could be done in the web interface and that you didn't need the Apex display unit. Sure enough I received my PM1 module, calibrated and activated the pH probe in the web interface and never needed the Apex display. I'm loving the unit and it is very helpful for me now to track on a graph in the Apex Jr. the daily fluctuations of my pH. Also it can adjust pH for temperature, though I haven't used that yet. Would definitely recommend to anyone that wants to track pH!! 4.5 stars because of the out of date instructions and because the unit requires that all probes be purchased separately.
