FOGII Plus Digital Soil Calcimeter™ with UMP-2

The FOGII Calcimeter provides the measurement of carbonate content. It has a rugged design and is easy to use so that it is suitable for field campaigns.
Based on the Scheibler method it measures the temperature compensated pressure rise after application of hydrochloric acid. As such it replaces the lab Scheibler apparatus, and gives access to the on-site determination of the carbonate content. The Plus version comes with an integrated UMP-2, which allows the in-field measurement of the water content and the dry soil correction of the readings. This eliminates the obligatory drying step.
