Dissolved Oxygen Meters Product Description

The DO600 Dissolved Oxygen Meter can display the oxygen level as % saturation from 0-200% or concentration from 0-20.00 ppm (mg/L). The dissolved oxygen meters also have the ability to adjust for altitude (0-20,000 ft in 1,000 ft increments) and for salinity from 0 to 50 ppt. The dissolved oxygen meters display the oxygen level on a large LCD screen that supports an analog bar graph to indicate trends, a data hold feature, and a low battery indicator.

The DO600 Dissolved Oxygen Meter was designed to be easy to use in harsh environments. The dissolved oxygen meter’s electrode, under normal use, will last about 6 months before the electrolyte and dissolved oxygen meter’s membrane need to be replaced. The dissolved oxygen meters are waterproof to the IP67 standard, self calibrates on power up, and supports an automatic power shut off feature. The dissolved oxygen meters calibration will hold for up to one year if left unused. The dissolved oxygen meters include the DO electrode, protective sensor cap, spare membrane cap, electrolyte, four 1.5V SR44W batteries, and a 48 inch (1.2m) neckstrap.
