The system evaluated was comprised of the analyzer, a Model 61field probe,and a Model 18stirrer assembly (optional). Dissolved oxygen is sensed with a platinum-lead polarographic membrane type probe that is designed to be automatically temperature compensated. Temperature is sensed by a thermistor. Data are provided in the form of a visual display on an analog panel meter and through an analog recorder output jack. 收起
