Calcimeter is used to determine the Carbonate content CaCO3 in Limestone and Lime Marl.
It consist of a glass container in which the reaction between the calcium carbonate present in the product and a solution of hydrocloridric acid takes place. The gased product is collected and measured by a device connected to the container.
As the volume of the produced gas (Co2) is in relation to the CaCo2 amount contained in the material, it is possible to calculate the percentage of CaCo3.
