VIKING-DO600 Modular Touchscreen Dissolved Oxygen Meter
VIKING-DO600 is a modular touchscreen benchtop meter supplied with a DO-P module and polarographic electrode for dissolved oxygen, saturation and temperature. It measures 0.00–99.99 mg/L and 0.0–600.0 % saturation, calibrates in air-saturated water or zero-oxygen solution, compensates barometric pressure automatically and corrects salinity manually. Free channels take pH, pX, EC or optical DO-F modules later; three-level users, GMP logs (FDA 21 CFR Part 11) and CSV / PDF export are built in.
Overview
Applications
- BOD and wastewater: DO before and after incubation, aeration control, effluent checks.
- Environment and aquaculture: surface water, fish farming and aquarium water.
- Food and beverages: oxygen in water, wine, beer and process fluids.
- Regulated QC: user roles, GMP logs, forced calibration and verification records.
Why VIKING-DO600
- Wide DO range: 0.00–99.99 mg/L and up to 600 % saturation for supersaturated samples.
- Simple calibration: air-saturated water or zero oxygen; automatic barometric compensation.
- Modular 4 channels: add pH, pX, EC or optical DO-F modules; 1–4 parameters at once.
- Data and compliance: GMP log, CSV / PDF export, printer, PC, barcode scanner, autosampler.
