Meter determines conductivity, plus TDS, salinity and temperature. When brand-new, it comes with four-cell electrode, which covers the range of 0.1 µS/cm to 200 mS/cm. Built-in communications protocols (RS-232) enables fast downloading to a printer or PC. This meter comes with the power supply - as seen in photos. Appears un-used, but not guaranteed. Probes are not included.
