Rugged and reliable, the YSI 556 MPS water quality analyzer (Multi probe system) combines the versatility of an easy-to-use, easy-to-read handheld unit with all the functionality of a multi-parameter system. Featuring an IP-67, impact resistant case, the YSI 556 MPS simultaneously measures dissovled oxygen, pH, conductivity, salinity, temperature and ORP.

This monitor is designed for water quality applications and mainly used in the environmental industry.   While this unit comes with a 4m cable, it also rents with the option of a 10m or 20m cable and Flow Cell.

Carrying Case - the instrument comes standard with a soft-sided carrying case with enough space for the YSI 556 MPS, a 4m cable (10 meter cable optional), flow cell and calibrating supplies. A handstrap can be connected on either the right or left side of the instrument.

Key Features

  • Standard 4m cable (available with a 10m or 20m cable)
  • Stores over 49,000 data sets, time and date stamped
  • Field-replacable DO electrode modules; pH and pH/ORP probes
  • Easy-to-use, screw-on cap DO membranes
  • Compatible with Ecowatch for Windows data analysis software
