humimeter FS3
Cocoa and coffee moisture meter


For quality control of unpeeled coffee beans, peeled green coffee and roasted or milled coffee.


The determination of the water content during the individual production stages is essential in order to obtain a high-quality end product. Limit values must be checked and observed at all times. The coffee moisture analyzer humimeter FS3 is the ideal solution for producers, roasters, traders, transporters and many more.


In addition to coffee, the following sorts can also be measured: Cocoa beans, poppy seeds, pumpkin seeds, peas, soybeans, runner beans, wheat, rape, peeled rice, unpeeled and brown rice, linseed, sesame, buckwheat, sorghum, millet and millet.

Product presentation

The humimeter FS3 Coffee Moisture Meter is a portable measuring instrument for the determination of the absolute water content of coffee, cocoa and many other luxury foods and cereals. Handmade to the highest quality standards in Austria. The housing is made of robust stainless steel, the installed sensors ensures reproducible, precise measurement results.
The moisture analyzer and the accessories supplied are supplied in a practical, robust plastic case.
Each instrument is calibrated by hand in our internal test laboratory and tested according to strict quality guidelines. The humimeter FS3 moisture analyzer delivers the water content of the sample within seconds. The operation is very simple.


The coffee moisture analyzer uses the so-called capacitive measuring principle: The entire sample is interspersed with an electrical measuring field. This means that not only the moisture on the outside of the sample is determined. The FS3 measures the average moisture of the entire sample. This is particularly important for freshly dried or roasted products, as the core usually has a higher moisture content than the outside. The moisture analyzer shows the absolute water content of roasted coffee beans, for example, directly on the display. It is also possible to save the measurement results and transfer them to a PC with the optional interface or print them out on a mobile printer.

In order to increase measurement accuracy and reproducibility, the measurement is performed hectolitre compensated. This is achieved by precisely weighing in the sample quantity. For this purpose, a balance and a measuring cup are included in the scope of delivery. In this way, different bulk densities cannot influence the measurement results.

All FS3 rapid moisture analyzers are calibrated and tested using the EN-ISO 712 calibratable oven drying method.
The sample temperature is permanently measured within the measuring chamber, displayed and included in the humidity calculation (temperature compensation). The temperature range is from 0°C to 40°C and can optionally be displayed in °C or °F. The calibrated measuring range is from 0% to 40% water content. (the measuring range can vary depending on the product)


handling / measuring procedure  
The moisture analyzer automatically performs a self-calibration (adjustment) after each power-up in order to ensure precise measured values over the long term. This self-calibration only takes a few moments. Then you can use the moisture analyzer to select the characteristic curve for the type of food, luxury food or grain to be measured. Simply press one of the arrow keys. The measuring chamber must then be filled with the quantity of the respective sample indicated on the display. In order to determine the exact sample quantity, a scale and a measuring beaker are included in the scope of delivery.

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.
