Multiparameter water quality meter brings laboratory accuracy and the ease of push-button operation to water quality measurement in the field. The multiparameter water quality meter can measure thirteen parameters: pH, ORP, temperature, dissolved oxygen, conductivity, total dissolved solids (TDS), salinity, resistivity, specific conductance, ammonium, nitrate, chloride, and barometric pressure. Featuring a powerful sensor probe and state-of-the-art functions, the multiparameter water quality meter makes it easy to get highly reliable water quality data simply and quickly just by submersing the sensor in the water. The multiparameter water quality meter's display case has a waterproof design that allows you to work without concern of splashing or accidentally dropping the instrument in the water. The multiparemeter water quality meter is flexible enough to use for checking the quality of a broad range of water samples, from factory effluent to urban drainage, river water, lake and marsh water, aquatic culture tanks, agricultural water supplies, and sea water.
