  • Overview

    The YSI 58 is a proven field and laboratory instrument. The 58 displays oxygen concentrations in two temperature-compensated modes. The instrument offers manual salinity correction, recorder output, and operation from line power or batteries. The case also holds additional batteries for an optional DO field stirrer.

    • Portable
    • Lab and Field
    • Rugged
    • Works with a variety of YSI probes

    Instrument comes in 115V or 230V power supply. A probe must be purchased separately. The model 58 can be used with 5239, 5718, 5905, 5750, 5740 cable with 5739 probe. Probes, service and support will be available through 2024.
