Dissolved Oxygen Meters

Photo of Oakton® DO 2700 Benchtop Dissolved Oxygen Meter with Self-Stirring BOD Probe

The DO 2700 benchtop meter measures dissolved oxygen in mg/L, ppm, or % saturation with simultaneous temperature display in °F or °C. Brilliant backlit display with dynamic stability indication. Independent 100% and 0% calibration points provide accuracy over the entire range. Measurement accuracy can be increased by manual barometric pressure and salinity compensation—meter automatically calculates offset. Built-in automatic temperature compensation (ATC) provides greater precision by correcting for temperature variations.

The Oakton DO 700 meter measures dissolved oxygen in mg/L, ppm, or % saturation with simultaneous temperature display in° F or °C. DO is measured from 0 to 20 mg/L (ppm) or from 0 to 200% saturation to meet the needs of a wide array of applications. Independent 100% and 0% calibration points provide accuracy over the entire range. Measurement accuracy can be increased by manual barometric pressure and salinity compensation - meter automatically calculates offset.

The Oakton® waterproof DO 600 meter is a handheld, and dustproof meter. It measures dissolved oxygen (DO) and temperature within a substance and is commonly used for water and salt water testing, in dirty or wet environments. This meter features automatic temperature compensation (ATC), with single- or multi-point calibration. It has a large, LCD backlit, graphic display to provide ease of viewing, and to display indicators. The meter has an adjustable alarm to remind you when calibration is due.

The Portable Oakton DO 6+  can be used to test water quality in wastewater, surface water, ground water, or drinking water. A clear LCD display shows results in ppm or mg/L with enunciators to aid in use and troubleshooting. Six simple buttons allow for freezing readings, toggling between display units and temperature results, setup, calibration, and automatic barometric and salinity compensation after manual parameter inputs. Additional benefits of the DO 6+ allow you to view electrode slope, zero offset, and millivolt values for electrode diagnostics.
