  • Overview

    The DO200A offers fast DO response times in wastewater, surface water and aquaculture applications.

    Calibrates easily in a saturated air environment and displays in % or ppm (mg/L) values, giving you the best DO data quality possible. Available with 1-, 4- or 10-meter cable lengths.

    The DO200A can also be used in the laboratory with the 200-BOD self-stirring lab probe making the DO200A a true lab and field instrument.

    Screw on PE membranes make membrane changes easier than ever. The PE membranes also have faster response times and reduce stirring dependence greatly.
