Membrane-covered amperometric dissolved oxygen sensor — continuously measures DO between 0-20 ppm. The lower-cost alternative to the optical RDO when daily calibration burden is acceptable and maintenance staff is regularly on-site. Best for municipal and industrial wastewater aeration basins, where the 499ADO has decades of installed-base reliability. Membrane and electrolyte are field-replaceable; rebuild kits available for multi-year sensor life.
