The YSI Professional Plus handheld multiparameter meter 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 and temperature. Also a very powerful lab instrument for BODs, pH and ORP.

Additional probes are available on request which measure the following parameters: pH/ORP combination, ammonium (ammonia), nitrate, chloride.

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 Mil-spec connectors and a rubber overmolded case. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.

The instrument provides numerous benefits from the following features; 5,000 data-set memory, password protection, backlit display and keypad, graphic display with detailed Help functionality, re-cal prompts, user defined fields, detailed GLP, auto stable, Hold All Readings function, Data Manager software for the desktop, USB connection, auto-buffer recognition, and flexible folders and site lists for logging data.
