VIKING-M310FA Portable Multi-Parameter Water Analyzer
OVERVIEW
VIKING-M310FA by COLO.Science is a portable multi-parameter water analyzer that measures pH, ion-selective electrodes (ISE), conductivity (EC), dissolved oxygen (DO) and temperature in one compact platform. It also supports mV and pX and calculates resistivity, TDS and salinity, providing a complete toolkit for water and environmental analysis.
With a bright 3.5″ LCD, intuitive menus and GLP-compliant data storage of up to 500 data sets per parameter, VIKING-M310FA streamlines routine workflows in laboratories and in the field. IP65 protection, ATC/MTC and flexible measurement modes (auto-read, timed-read, continuous-read) make it a robust choice for water utilities, industry and environmental monitoring teams.
TYPICAL APPLICATIONS
- Water quality testing in laboratories and water treatment plants.
- Environmental monitoring of surface water, groundwater and effluents.
- Industrial process control in food, beverage, chemical and power plants.
- On-site inspections, field surveys and mobile sampling campaigns.
- Education and training in universities, colleges and technical institutes.
