About This Product
Oxygen dissolved in water is an index of biological and physical processes, and this table-model dissolved oxygen meter reads it through an amperometric gold/silver membrane probe. Readings from 0 to 20.0 ppm appear on a 3½ digit LED display, with temperature compensation from 0°C to 50°C and a manual D.O. compensation setting. It is a 2 kg, 230 V AC unit within Laboratory Instruments for water testing.
