Neptune PM1 pH/ORP Probe Module
The Neptune PM1 pH/ORP Probe Module is an expansion module for the Neptune Systems Apex that adds pH or ORP monitoring to your aquarium controller. It also gives you ports for a temperature probe and a Breakout Box, so it suits reefkeepers who want to get more from their Apex.
Key Benefits
- Adds pH or ORP monitoring to the Apex, depending on which probe you connect
- Works with all Apex systems
- Includes an extra temperature probe port, so you can monitor a second tank or the air around your aquarium
- I/O port for connecting the Apex Breakout Box
- Two AquaBus ports for connecting to your Apex system
How to Use
Connect the module to your Apex with the AquaBus cable, then plug in the probe for what you want to monitor. Probes and accessories are sold separately.
- pH/ORP probe port: Use either a pH probe or an ORP probe. If you run two aquariums near each other, a pH probe on the PM1 lets you monitor both tanks from the same Apex system. If you run a calcium reactor, a pH probe inside it can monitor the reactor's pH and automate a CO2 solenoid. An ORP probe lets you automate specialised equipment such as an ozone generator.
- Temperature probe port: An additional temperature probe can monitor the temperature of another aquarium. Placed elsewhere, it can also monitor the ambient air around your aquarium.
- I/O port: Connect your Apex to the Breakout Box, an accessory that is easy to overlook. The Breakout Box lets you connect up to 6 different switches or buttons to trigger feed modes, timers and more.
Suitable For
- Apex owners who want to add pH or ORP monitoring
- Reefkeepers running a calcium reactor who want to automate a CO2 solenoid from the reactor's pH
- Aquarists running two tanks side by side from one Apex system
- Hobbyists who want to automate equipment such as an ozone generator using ORP
- Anyone who wants to add switches or buttons for feed modes and timers through the Breakout Box

Frequently Asked Questions
Does the PM1 come with a pH or ORP probe?
No. The kit contains the PM1 module and a 91 cm (3') AquaBus cable. Probes and accessories are sold separately.
Can I use the PM1 for both pH and ORP?
The module has one pH/ORP probe port. You connect either a pH probe or an ORP probe, depending on what you want to monitor.
Will the PM1 work with my Apex?
Yes, the PM1 is compatible with all Apex systems.
Can I use the PM1 to monitor a calcium reactor?
Yes. Connect a pH probe to monitor the pH inside the reactor, which you can use to automate a CO2 solenoid.
What can I do with the temperature probe port?
An additional temperature probe lets you monitor the temperature of another aquarium. Placed away from the water, it can also monitor the ambient air around your aquarium.
What does the I/O port connect to?
It connects your Apex to the Breakout Box, which lets you connect up to 6 different switches or buttons to trigger feed modes, timers and more.
