Portable Oxygen Meter

The Sper Scientific dissolved oxygen meter gives reliable DO readings at a reasonable price and has the option to read pH, mV/ORP, conductivity, TDS, salinity and temperature with optional probes.

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. Features simple one-button calibration to air. DO probe heads include built in membranes and screw on and off for easy replacement.

Also uses optional, interchangeable probes to read pH, millivolt (mV)/ oxygen reduction potential (ORP), conductivity, total dissolved solids (TDS), salinity, and temperature. Order only the probes required for your current parameters and add additional probes in the future. (sold separately).

Comes in a hard carrying case complete with one DO probe, two spare probe heads, electrolyte, instructions and a 9V battery.
