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.
The ProQuatro was designed with the 4-port Quatro cable in mind. Combine 4 sensors on a single cable for comprehensive multiparameter sampling to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate. Pairing the ProQuatro with the 4-port cable creates an extremely powerful handheld multiparameter water quality instrument.
The ProQuatro meter meets the demands of true field work. Made from ultra-rugged components to withstand harsh field conditions, 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 over-molded case, scratch-resistant lens, and a 2-year cable warranty. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.
