Portable Water Quality Meters
pH, Conductivity, Dissolved Oxygen, Turbidity and Multi Parameter
Portable water quality meters are
handheld field instruments designed to
measure one or more parameters directly in a water sample —
without returning to a laboratory. They are the standard tool for
environmental field surveys, water treatment plant monitoring, groundwater
assessment, aquaculture management, and industrial process
control where real-time, on-site results are required.
Nexbio supplies portable water quality meters from HORIBA, all from the LAQUA instrument range. 2 main series are available, the 200 Standard Series and the 300 Smart Series. All LAQUA portable meters are IP67 rated with data logging and GLP data management available in certain models.
