Water Quality

These water quality instruments can test for, measure, monitor and record a variety of parameters both in the lab and in the field. Choose from colorimeters, conductivity meters, dissolved oxygen meters, fluorometers, ISE meters, pH meters, refractometers, spectrophotometers, turbidity meters and more. For an extended deployment, a multi-parameter sonde with a choice of sensors will log an array of data.
