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 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.

 If you're interested in dissolved oxygen measurements you may also be interested in our Professional Series products Pro20 or optical DO handheld ProODO.
