The Eureka Sub2 multiparameter water-quality multiprobe measures temperature, optical dissolved oxygen, conductivity, pH, depth or level, and ORP – all in one package that delivers data in the toughest field conditions. Our multiprobes are known worldwide for ease of use, reliable data, and economical operation.

The Sub2 delivers professional-grade data in fresh or salt natural waters to 200 meters deep. It’s designed for ease of use with direct USB connection to your PC, automatically loading software, operating-status LED’s, and a PDA-based field data display that uses the same software as your PC. With features like a refillable reference electrode and virtually unbreakable cables, the Sub2 has the lowest lifetime cost of any multiprobe on the market.

  • Highly reliable water-quality data for temperature, optical dissolved oxygen, conductivity, pH, depth or level, and ORP
  • Learn the software in 10 minutes
  • Industry-best customer service
  • Use in lakes, rivers, estuaries, aquifers
  • Manual mode, unattended logging mode, and/or real-time telemetry mode

  • Underwater cables – use underwater cables with your multiprobe when you are doing manual surveying or using telemetry; they are not necessary for unattended logging applications.
  • Power options – use a Y-cable when you have your own power supply (such as in telemetry systems) or use a Battery Box (rechargeable lithium-ion battery) with a data display or with cables longer than 50 meters; the Battery Box also comes with a Bluetooth option which allows operation of a data display without holding onto the cable at the same time.
  • SDI-12 and TTL adapters – use the SDI-12 adapter to convert your multiprobe output from RS-232 to SDI-12; use the TTL adapter to make the multiprobe output compatible with third-party devices (such as some data loggers) that require TTL signal levels.
  • Battery packs for logging – order the Internal Battery Pack when you order a 3.5”, 4”, or 4.5” multiprobe if application is unattended logging, or order an External Battery Pack at any time for your 2”, 2.5”, 3”, Sub2, and Sub3 multiprobes if your application is unattended logging.
  • Calibration solutions – check out our supply of all the popular calibration solutions at good prices and delivery times.


Realted Product
Eureka 2 water-quality multiprobe - the Eureka 2 provides your choice of up to 14 sensors from a selection of 22 sensors for the most extensive data requirements and most demanding field conditions.
Eureka Sub3 water-quality multiprobe - the Sub3 is an economical Eureka 2 multiprobe specially configured with temperature, optical dissolved oxygen, pH, conductivity/ salinity/ TDS, ORP, depth or level, and turbidity built into a housing less than 3” diameter.
Eureka DD2 data displays – the DD2 is a waterproofed PDA useful as a field data display for Eureka 2 multiprobes while retaining all the utility of a PDA; it uses the same user-interface software as the Eureka 2’s PC interface so you don’t have to learn two software structures.
Eureka TS2 telemetry systems – the TS2 telemetry system installs in the field in minutes with no user programming; you can view data at any Internet connection. The TS2 uses your choice of cellular or satellite communications for
high reliability at lowest cost.
