The Calcium Carbonate Content Chamber indexes the presence and amount of calcium carbonate (CaCO3) in soil specimens. Within the sealed 2.5 x 5.5in (63.5 x 140mm) IDxH clear acrylic chamber, samples are treated with hydrochloric acid (HCI). The resulting pressure is measured via a 10 psi (69kPa) Bourdon-tube pressure gauge. This pressure is then correlated to the user-defined data reduction method to determine the carbonate content of the sample. This unit comes with the pressure gauge, sealing O-Rings, and a 20ml cup with handle.
