This Dissolved Oxygen Meter Kit from Sper Scientific measures dissolved oxygen to determine water quality in environmental testing, labs, industrial and municipal waste water, aquariums and fish hatcheries. The back-lit display simultaneously displays dissolved oxygen (in % or mg/L) and temperature readings (in °C or °F). Automatic temperature compensation as well as manual compensation for salinity and altitude (all factors affecting DO readings). Features simple one-button calibration to air. DO probe heads include built in membranes and screw on and off for easy replacement. Also functions as a pH, ORP, Conductivity, TDS or Salinity meter when used with the optional probes. Comes in a hard carrying case complete with DO probe, two replacement probe heads with diaphragms, DO electrolyte, instructions and a 9V battery. Kit dimensions are 11" × 9½" × 2".
