VIKING-DO310 — Portable Dissolved Oxygen Meter · Polarographic DO/Temp. (DO Saturation) · 3.5″ LCD
OVERVIEW
The VIKING-DO310 portable dissolved oxygen meter is designed for reliable field and laboratory measurements of
dissolved oxygen concentration (ppm), DO saturation (%) and temperature using a
polarographic DO sensor. A clear 3.5″ LCD supports practical operation for routine monitoring, while
the workflow includes Auto-Read (Fast/Medium/Slow), Timed and Continuous measurement modes and
Auto-Hold endpoint locking to reduce operator variability.
For documented water quality workflows, VIKING-DO310 supports GLP-compliant data storage and
USB communication for reporting. Built-in automatic barometric pressure compensation and
manual salinity factor correction, combined with a robust IP65 housing, make DO310 a practical solution for
environmental monitoring, wastewater checks, aquaculture control and routine DO spot checks.
Portable dissolved oxygen meter (polarographic) with 3.5″ LCD for DO (ppm), % saturation and temperature.
Includes Auto-Hold, GLP logging, USB export, pressure/salinity compensation and IP65 protection for field monitoring.

Product Overview
VIKING-DO310 is built for portable dissolved oxygen measurements where repeatable endpoints and documented results matter. The instrument measures DO concentration and % saturation, plus temperature, and supports practical correction tools (pressure + salinity) for more reliable reporting across varying field conditions.
Configuration notice — delivery depends on selected options
Portable DO meters may be delivered in different configurations depending on the application and selected accessories. The official technical specification defines the exact configuration, included components and available options for each model/variant.

Portable dissolved oxygen meter for routine monitoring
A portable dissolved oxygen meter is commonly used for quick DO verification in surface water,
wastewater treatment, aquaculture tanks and process water control. VIKING-DO310 combines
polarographic DO sensing with practical workflow tools such as Auto-Hold, pressure compensation and
salinity correction to help operators report more consistent DO (ppm) and % saturation values
across changing field conditions. For documentation, USB transfer and GLP-style logging support basic reporting needs.
