SECURE METER

摘要

A compact multiparameter instrument for electrochemical measurements is de-scribed. The instrument facilitates rapid engagement and disengagement of a variety of sensor elements in such a manner as to prevent accidental mismatch of sensor elements and sensor input ports. Positive identification of specific sensors is ensured by including color marking or other indicia on the sensor connectors that are matched to corresponding markings on the meter body. Measurements of specific parameters such as temperature may readily be shared among all other sensors connected to the instrument. A method of rapidly reconfiguring the instrument to provide extended or different capabilities is de-scribed.
