Overview

The YSI ProSolo is YSI's most advanced handheld optical dissolved oxygen meter. It connects to any ODO/T or ODO/CT probe on cables from 1 to 100 m; optical luminescent sensing needs no stirring, membranes or electrolyte. An optical BOD probe is available for laboratory BOD/CBOD testing.

  • Works with ODO/T (DO and temperature) and ODO/CT (adds conductivity and real-time salinity compensation) probes
  • Optical DO sensing: no stirring, no membranes, no electrolyte, less drift
  • Smart probes store calibration, so they move between handhelds without recalibration
  • EPA-approved methodology for DO compliance (ODO/T) and for BOD/CBOD (OBOD probe)
  • Over 100,000 data sets, 100 sites and 100 data ID tags; export to a USB flash drive without a computer
  • Colour display and backlit keypad; user-replaceable lithium-ion battery
  • IP-67 waterproof case, military-spec connector, drop tested
  • 3-year handheld warranty; 2-year probe, cable and ODO cap warranty

Handheld only: choose an ODO/T or ODO/CT probe and cable separately. Request a quote for pricing and availability.
