ProQuatro Multiparameter Meter Introduction：

user's manual datasheet

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 highlights of the ProQuatro Multi-Parameter Meter include：

Toughest

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.

Tough, Field Durability Features Include:

Rubber, over-molded IP-67 waterproof case (even without the battery cover)*
Drop-tested 1 meter at all angles*
3-year instrument warranty
2-year cable warranty*
Rugged cables, sensors, and military-spec connectors*
Weighted, user-replaceable multi-sensor design
