VIKING-M500 Benchtop Multi-parameter Analyzer
VIKING-M500 is a research-grade benchtop touchscreen multi-parameter analyzer for pH, conductivity, ion concentration, dissolved oxygen and temperature in one instrument. It combines a 7.0″ colour touchscreen, pH ±0.002 pH, conductivity ±0.5 % FS, ISE ±0.3 %, DO 0.00 to 99.99 mg/L, 1000-result GLP memory and IP54 protection.
Overview
Applications
- Water and wastewater: pH, conductivity, ions and oxygen in drinking, surface and waste water.
- Environment and aquaculture: monitoring of rivers, lakes, wells and fish farms.
- Food, pharma and industry: process water, solutions and quality control.
- Education and research: several methods on one instrument instead of several meters.
Why VIKING-M500
- One instrument: pH / EC / ISE / DO / Temperature with separate electrode inputs.
- Clear display: 7.0″ colour touchscreen with guided menus for measurement, calibration and data.
- Calibration: pH up to 6 points with buffer recognition, conductivity up to 5 points, ions up to 6 points.
- Data traceability: 1000 results per parameter, GLP; USB 2.0 (flash drive, PC, scanner), RS-232 (printer, autosampler).
