Solinst Water Level Meter

The YSI 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.

EPA approved for drinking water and wastewater compliance reporting.

The ProQuatro Multiparameter Handheld was designed to be used with the 4-port Quatro cable. Combine 4 sensors on a single cable for comprehensive multiparameter sampling to measure temperature/conductivity, DO, and any two ISEs (pH, ORP, ammonium, chloride, or nitrate).
