This invention relates to a fluid screening device, comprising: an impedance sensor 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 for measuring the impedance of the impedance sensor with respect to at least one frequency; a processor for processing impedance data taken by the impedance measuring circuit for purposes of determining a condition of the fluid; and a connector which operatively couples the impedance sensor to the impedance measuring circuit, the connector allowing the impedance sensor to be selectively detached from the impedance measuring circuit.
