The U53-2 Meter with 2m Cable simultaneously monitors, collects and stores pH, Oxidation Reduction Potential (ORP), Dissolved Oxygen, Conductivity, Salinity, Total Dissolved Solids (TDS), Seawater Specific Gravity, Temperature, Turbidity (Tungsten Lamp) and Water Depth. It is designed to be both rugged and easy to operated, making it the perfect solution for fieldwork. Ideal for sampling rivers, groundwater, wells, lakes, runoff/drainage and a multitude of other ecological and agricultural applications.
