VIKING-M500 — Benchtop Multi-Parameter Analyzer (pH / EC / ISE / DO / Temp.)
OVERVIEW
VIKING-M500 is a benchtop multi-parameter analyzer for precise
pH, conductivity (EC), ion concentration (ISE) and dissolved oxygen (DO) measurements.
The 7.0″ color touchscreen, intelligent OS and GLP-compliant memory (up to 1000 data sets) make it a central instrument for routine and advanced electrochemical analysis.
The instrument supports multiple reading modes, 1–6 point calibration, flexible buffer groups and temperature compensation (ATC/MTC).
With USB and RS-232 connectivity, the VIKING-M500 integrates smoothly into laboratory workflows, data archiving and reporting.
