Description
The Foxboro 873DO is a line-powered, dual sensor input dissolved oxygen analyzer. The 873DO analyzer is used with the 871DO-C sensor for parts-per-million measurements of dissolved oxygen in aeration basins, industrial and municipal wastewater treatment plants, and aquaculture applications. When used with the 871DO sensor, the 873DO offers several sensor diagnostic features. The analyzer periodically monitors the sensor for membrane fouling, membrane breakage, and loss of internal filling solution. Calibration of the 873DO is quick and simple, achieved by allowing the sensor to stabilize in ambient air. Each 873DO analyzer provides two analog output signals (4-20 mA, 0-10 V, 0-20 mA) and two alarm relays. A choice of plastic, panel-mount or metal, field-mount enclosure is available. Each enclosure is ¼ DIN. The metal enclosure is rated NEMA 4X, while the plastic enclosure is NEMA 12 from the front and NEMA 1 from the rear.
