VIKING-DO500 — Benchtop Dissolved Oxygen Meter · DO / Temp · DO Saturation · 7.0″ Touch LCD
VIKING-DO500 benchtop dissolved oxygen meter
OVERVIEW
The VIKING-DO500 benchtop dissolved oxygen meter is designed for reliable DO concentration,
DO saturation and temperature measurements using a polarographic DO sensor.
A 7.0″ color high-contrast touchscreen and an intelligent operating system support user, calibration,
method, data and GMP management, making the instrument suitable for routine laboratory workflows and
controlled reporting environments.
VIKING-DO500 supports Auto-Read (Fast/Medium/Slow), Timed and Continuous
reading modes, ATC/MTC temperature compensation, air-saturated water or
zero oxygen calibration, automatic barometric pressure compensation and
manual salinity factor correction. With 1000 GLP data groups, on-instrument review
and recalculation tools, plus USB / RS-232 communication, it is a robust platform for dissolved
oxygen analysis supported by COLO.Science.
Benchtop DO meter with 7.0″ touchscreen for DO (ppm), DO saturation (%)
and temperature, featuring GMP/GLP data management, automatic pressure compensation,
salinity correction and flexible connectivity (USB/RS-232).

Product Overview
VIKING-DO500 benchtop dissolved oxygen meter provides accurate DO concentration and DO saturation results
with a polarographic sensor and built-in compensation tools. The interface is optimized for day-to-day lab use, while
the operating system supports structured work (users, methods, calibration, data review and GMP/GLP logging) for
traceability in regulated or documentation-heavy environments.
