Sper Scientific* Benchtop Water Quality Meter - Each

Reads pH, ORP (oxygen reduction potential), mV, conductivity, TDS (total dissolved solids), salinity, and temperature. Rugged housing with large LCD displaying the parameter being measured together with time, date and temperature (in °C or °F). Operates on AC voltage (no batteries). Comes ready to use with ATC conductivity and pH electrodes, multiple electrodes holder arm, AC adaptor, computer cable, and software. Also accepts any pH or ORP probe with a standard BNC connector.
