Abstract: A fluid testing system comprises controlling hardware that serves to control an electric sensor on a fluid testing cassette. In one implementation, the controlling hardware is part of a cassette interface. In another implementation, the controlling hardware is part of the portable electronic device. In one implementation, the fluid testing system applies two different frequencies of alternating current are applied to two different electric sensors.

Abstract: An apparatus includes a microfluidic passage, a chamber, an inlet connecting the microfluidic passage to the chamber, a sensor proximate the inlet to sense fluid within the inlet, a first nozzle, a first fluid driver to move fluid through the first nozzle to draw fluid across the inlet, a second nozzle, a second fluid driver to move fluid through the second nozzle to draw fluid across the inlet and a controller. The controller sequentially actuates the first fluid driver and the second fluid driver.
