VIKING-M600 by COLO.Science is a touchscreen benchtop
multi-parameter analyzer designed for precise measurement of
pH, conductivity (EC), ion concentration (ISE) and
dissolved oxygen (DO), with temperature compensation, GLP-compliant data storage
and smart, guided workflows.

With a 7.0″ color LCD, modular channels (pH/ISE, EC, DO) and up to
1000 stored results per parameter, VIKING-M600 is ideal for water laboratories,
environmental monitoring, industrial QC and research applications that require traceable
multi-parameter analysis at the bench.
