  • Overview

    The YSI Pro20 dissolved oxygen meter is a rugged, user-friendly instrument for measuring dissolved oxygen or BOD that can be used interchangeably in the lab and the field. Depending on your needs, you can choose between a Polarographic DO sensor, a Galvanic DO sensor, or a BOD probe.

    Top Features

    • User-replaceable sensors and cables
    • One Touch Cal for convenient and quick calibration
    • Choice of DO sensor (Polarographic or Galvanic) or lab BOD probe for BOD in wastewater
    • Military spec connectors, IP-67 waterproof, and 1-meter drop tested
    • Rubber over-molded case
    • Low total cost of ownership
    • Internal barometer for highest accuracy
    • 95% response in 8 seconds with standard membrane
    • Stores 50 data sets
    • Graphic, backlit display and glow-in-the-dark keypad visible with polarized sunglasses on
    • Available with 1, 4, 10, 20, 30 or 100-meter cables
    • Multiple languages including English, Spanish, French, and German
    • 3-year instrument warranty; 2-year cable warranty; 1-year polarographic sensor warranty; 6-month galvanic sensor warranty

    Polarographic or Galvanic?

    Fast response times with the Polarographic or Galvanic dissolved oxygen sensors allow you to complete your sampling routine quickly. The long life of the Polarographic sensor saves time, money, and reduces your overall cost. The Galvanic sensor enables sampling to start immediately without a warm-up period. Regardless of sensor selection, you will receive accurate, quality data!


    Please visit the Pro20 Kits page for fully assembled systems. For an integral cable assembly (not user-replaceable), YSI offers the Pro20i.

    Please visit our extensive dissolved oxygen resource page to learn about DO and BOD-related things: www.YSI.com/weknowDO.

    You can also download The Dissolved Oxygen Handbook, which covers all things DO-related, from technologies to maintenance and calibrations to acquiring the best data.
