Neptune PM3 – Dissolved Oxygen Module
This item must be used with a Neptune Apex controller, it cannot be used stand alone.
DISSOLVED OXYGEN PROBE NOT INCLUDED
REAL-TIME MONITORING OF DISSOLVED OXYGEN IS A GREAT SAFETY NET
Many marine aquarists only give the oxygen content in their aquarium water a passing thought, not fully understanding how the level of the Dissolved Oxygen (DO) in their tanks can affect their entire tank population. In one way or another, everything (fish, invertebrates, corals, algaes, bacteria) in the oceans and in marine aquariums react with oxygen. Most of the living beings of this planet require oxygen in order to metabolize nutrients. Fish, invertebrates, corals, and bacteria ingest O2 and expel CO2 day and night.
FEATURES OF THE SALINITY MODULE INCLUDE:
Monitor/Control Dissolved and temperature
6 digital inputs for float switches, water on floor sensors, pressure sensors, etc
Full datalogging 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
Two AquaBus connectors for flexible expansion via AquaBus
Comes with 3′ AquaBus cable
Galvanic Isolation for accurate and reliable probe readings
LED Status Indicator
Compatible with all Apex systems
DISSOLVED OXYGEN PROBE SOLD SEPARATELY
While the cost of the Dissolved Oxygen Module – PM3 is very reasonable, the down side is that the DO probe itself is relatively expensive. The DO Probe certified and sold by Neptune Systems is a lab grade device and costs about 5x the cost of the PM3 module itself. That’s the bad news. The good news is that the probe has replaceable membranes so you don’t have to throw it away when it wears out like other probes. Instead, every three months you simply put a new membrane in the probe – at a cost of only $8.
