Abstract

The device has a water detection device (5) for determining a water parameter for the absolute quantity of water arising in a reaction, a gas detector (9) for detecting a gas parameter for a gas quantity in or through the reaction region (1) and a computer unit (7) for computing the moisture content of the gas flow at least from the parameters for water and gas quantity.. Independent claims are also included for the following: (A) a control circuit with an inventive device (B) and a method of indirect determination of the moisture content of gases.
