After that, the corresponding calibration curve can be selected at the moisture analyser for food. Subsequently, the measuring chamber of the food moisture meter is filled with the quantity of the respective sample indicated in the manual. To determine the exact quantity the humimeter device is delivered with a balance and measuring cup.

The water content can immediately be read off the large, well-lit display of the food moisture tester and saved, edited or printed out via the integrated datalog if required.

Therefore the Humimeter FS3 is also called coffee moisture tester and cocoa moisture meter.

Via the integrated datalog the measuring values can be stored on the food moisture meter and additional data can be added. You also have the possibility to use the hold function. This function freezes the last measuring value on the display of the food moisture tester until another button is pressed.

In order to increase the measurement accuracy and reproducibility, the measurement is carried out with hectoliter compensation. This is achieved by accurately weighing the sample amount. For this purpose, a scale and a measuring cup are supplied with the food moisture meter. As a result, different bulk densities have no influence on the measurements.

The entire food moisture measuring device series was calibrated and checked using the calibratable drying method EN-ISO 712.

Simultaneously, also the sample temperature is measured and included it in the calculation of the measuring result. The calibrated measuring range of our moisture analyser for food goes from 0% to 40% water content (depending on the product).
