The sample material is weighed and placed into a sample tray. The sample tray itself is part of an integrated reactor within the HydroTracer. A heater warms the sample to the selected temperature. The water evaporating from the sample reacts with the powdery reagent in a cooled area and water is transformed into hydrogen. The concentration of hydrogen gas is measured. It is a measure for the amount of water in the reactor.

The concentration of hydrogen is a measure of the sample humidity. The percentage of water of the sample is calculated by division with the sample weight.

Category:
1. The test material is heated in the sample tray, water evaporates
2. The hot humid gas ascends
3. The reagent exchanges water by hydrogen
4. The sensor detects the concentration of hydrogen.
5. The cooled gas descends and can absorb water again
