Provided is a dust measurement apparatus for accurately measuring the dust concentration of two spaces and minimizing the possibility of noise generation, comprising: a dust sensor; a body housing having the dust sensor loaded therein, and having an inner space; a first outer hole and a second outer hole, which are respectively formed at two points of the body housing so as to connect the outside and the inner space; a first fan and a second fan, which are provided at the positions corresponding to each of the first outer hole and the second outer hole and driven so as to form a flow toward the inner space from the outside; and a control part for selectively driving the first fan or the second fan.

Dust measurement apparatus

Disclosed are an apparatus and a method for effectively measuring cholesterol using a small amount of blood. The apparatus for measuring cholesterol includes a cartridge where an upper case having a sample transferring membrane is movably coupled to a lower case having a sample measuring membrane; a cartridge accommodation unit configured to accommodate the cartridge therein; a memory configured to store therein setting information for sample measurement; and a controller configured to align the membranes of the upper case and the lower case with each other, by horizontally moving the lower case of the cartridge, according to the stored setting information, and configured to contact the membranes of the upper case and the lower case with each other, by vertically moving the upper case for sample transfer on each alignment position.
