Description
Overview
GAOTek Handheld Multiparameter Water Quality Meter Analyzer is a portable multi-parameter water quality monitoring instrument used for testing water quality. It can be installed with up to 4 probes (built-in pressure sensor is for optional), can measure water quality parameters as below: Temperature, Conductivity, pH, ORP, Turbidity, Dissolved Oxygen, also can be replaced by Chlorophyll, Blue-green Algae, NH4+, K+, TSS, Salinity etc. based on customers’ requirements.
