The YSI Pro Plus provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium, nitrate, chloride and temperature.

The YSI Pro Plus display features an internal barometer for dissolved oxygen calibrations, internal data logging for up to 5,000 data-sets, password protection, backlit display & keypad, and direct USB interface with software for uploading data, configuring the instrument, and conducting real-time studies. Connect any cable and probe option to the instrument and use the convenient cable management kit to keep everything simple and organized. Cable options range from 1m, 4m, 10m, 20m, and 30m choices (up to 100m on DO only cables).

The Pro Plus instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on. Other tough features include a 3 year display warranty, Mil-spec connectors, rubber over-molded case, and a 2 year cable warranty. In-house testing procedures also include 1m drop tests from all angles to ensure expected field-durability.
