FOGL - Laboratory calcimeter with large touch screen display

The FOGL laboratory calcimeter enables the measurement of carbonate content in soil samples. This is a crucial parameter for soil fertility and plant health, but also in other areas such as cement production, pottery or drilling. With digital recording of data, ease of use and small footprint, the FOGL offers many advantages in the laboratory over the traditional Scheibler apparatus. Based on the Scheibler method, the temperature-compensated pressure rise is determined after hydrochloric acid is added. When the measurement is finished, the result is immediately displayed and automatically stored.
