Calcite buildup in drilling fluiids and water treatment processes causing scaling problems.  Data from Fann Calcimeters can help determine the proper chemical treatment.  Calcimeters can determine quickly and with a high degree of accuracy if the scale buildup is composed of calcium carbonate.  Calcimeters are suited to a differential measure of the calcite to dolomite content of the unknown sample.

These instruments comply with the ASTM D 4373-84 Standard Test Method for Calcium Carbonate Content in Soils. This test method is under the jurisdiction of ASTM Committee D-18 on Soil and Rock and is the direct responsibility of Subcommittee D-18.13 on Marine Geotechnics.
