YSI ProQuatro Multiparameter Meter

Xylem - YSI

The ProQuatro handheld multiparameter meter measures a variety of combinations of dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature. Also a very powerful lab instrument for BODs, pH and ORP.

Toughest

The ProQuatro 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 warranty, Mil-spec connectors, rubber overmolded case, and a 2-year cable warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.

Smartest

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, USB connection, auto-buffer recognition, and flexible folders and site lists for logging data.

Most Versatile

Connect any Professional Series cable and probe option to the instrument and use the convenient cable management kit to keep everything simple and organized. Cable options range from 1-, 4-, 10-, 20-, and 30-meter choices (up to 100-meters on DO only cables). Use lab or field probes and switch between the two quickly. The ProQuatro makes an ideal lab BOD instrument with the proven self-stirring BOD probe (EPA Approved). A convenient handstrap can be used on either side of the instrument.
