VIKING-M300A Benchtop Multi-parameter Analyzer
VIKING-M300A is a benchtop multi-parameter analyzer for pH, conductivity, ion concentration and temperature in one instrument. It combines a 7.0″ backlit LCD, pH ±0.01 pH, conductivity ±1.0 % FS, ISE ±0.5 %, 500-result GLP memory and IP54 protection.
Overview
Applications
- Water and wastewater: pH, conductivity, ions 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-M300A
- One instrument: pH / EC / ISE / Temperature with separate electrode inputs.
- Clear display: 7.0″ LCD with backlight with Reading / Stable / Locked prompts.
- Calibration: pH up to 5 points with buffer recognition, conductivity up to 3 points, ions up to 5 points.
- Data traceability: 500 results per parameter, GLP; USB (PC), RS-232 (printer).
