PORTABLE FLUID SCREENING DEVICE AND METHOD

摘要

This invention relates to a fluid screening device (10), comprising: an impedance sensor (22) including a cavity for holding a fluid to be screened, an impedance of the impedance sensor being affected by conditions of the fluid; an impedance measuring circuit (38) for measuring the impedance of the impedance sensor with respect to at least one frequency; a processsor (34) for processsing impendance data taken by the impedance measuring circuit (38) for purposes of determining a condition of the fluid; and a connector (25) which operatively couples the impedance sensor (22) to the impedance measuring circuit (38); the connector (25) allowing the impedance sensor (22) to be selectively detached from the impedance measuring circuit (38).
