This hand-held, portable meter is designed to provide quick, accurate field measurements for this critical environmental water quality parameter. Easy, push-button mode selection allows the analyst to obtain dissolved oxygen readings in mg/L or percent saturation, as well as temperature in °C. Features include automatic temperature compensation for dissolved oxygen
readings, and manually adjusted salinity compensation. Meter comes packaged in a convenient carrying case with combination temperature and DO probe, replacement membrane cartridges and membranes, electrolyte, and protective probe storage sheath.
