Abstract
A circuit with at least one catalytic measuring element (), in which the at least one catalytic measuring element () is connected to a supply voltage () without a protective resistor and without a thermal safety device arranged upstream. The circuit makes it possible to develop gas-measuring devices with catalytic measuring elements that are characterized by an especially low power consumption.
