HydroTerra Pty Ltd  supplies the Eureka Sub 2” ODO multiprobes specially designed to operate in 50mm groundwater monitoring bores.

The Eureka Sub 2” ODO multiprobes can be used for simultaneous monitoring of six different parameters including Dissolved Oxygen, Conductivity, pH, Oxidation-Reduction Potential (ORP), Depth and Temperature.

The Eureka Sub 2" ODO is a self-contained unit, less than 50mm in diameter.

The optical dissolved oxygen sensor simply relies on the interaction of light with oxygen in the water, and does not use membranes, which can be easily fouled requiring frequent replacement.

As with all Eureka Manta monitoring instruments, the Sub 2" ODO multiprobes offer the following features: 

  • Telemetry capable
  • Can be specified with a battery pack for long-term groundwater monitoring
  • Can be connected to the rugged Amphibian handheld data display for field data retrieval in difficult conditions
