The instrument can measure three electrochemical quantities at the same time: pH or ORP, conductivity, TDS or
salinity, dissolved oxygen and temperature. Three optoisolated inputs. Input 1: pH, ORP or temperature. Input 2:
dissolved oxygen or temperature. Input 3: conductivity, total dissolved solids, salinity or temperature. It can measure,
store or download the readings through the multistandard RS232C/USB2.0 serial port.
