YSI DO 200

Dissolved Oxygen / Temperature Meter YSI DO 200 Compact and affordable, the DO 200 provides quick, accurate dissolved oxygen and temperature measurements simultaneously. The screw-on cap membranes reduce stirring dependence, offer fast response times, and are easy to replace. The weighted probe assembly sinks quickly and is protected from impact. Dissolved oxygen measurements are displayed in either % oxygen saturation or ppm ( mg/ L) . Other features include a watertight housing which meets IP-65 specifications, low battery indicator, push-button calibration, and compensation for temperature, pressure, and salinity for accurate measurements in varying conditions. Two cable lengths available. One-year warranty on instrument. One-year warranty on cable and electrode. Specifications: Range: 0% to 200% air saturation; 0 to 20 ppm; -6º C to 46º C. Resolution: 0.1% air saturation; 0.01 ppm; 0.1º C. Accuracy: ± 2% of the reading or ± 2% air saturation, whichever is greater; ± 2% of the reading or ± 0.2 ppm, whichever is greater; ± 0.3º C ± 1 digit.
