The calcium carbonate content chamber test rapidly determines the calcium carbonate content of soils. A 10 psi Bourdon tube pressure gauge comes pre-calibrated with reagent grade calcium carbonate. The calcium carbonate features a sealed 2.5″ID x 5.5″H clear acrylic chamber assembly that anodizes aluminum end caps. In addition, the content chamber includes a pressure gauge, bleed valve and 20ml cup with handle.
