Abstract
The disclosure provides a gas detector with an ionizing device for producing ions depending on a gas to be detected. The gas detector includes a catcher for receiving the electrical current produced by the ions, and a measuring device with an electrical measuring resistor. The electrical measuring resistor produces an electrical measuring potential from the current and is surrounded, at least in part, by an electrical shield resistor, denoted by RT. The same potentials, up to a deviation of at most 25%, are applied in the longitudinal direction of the electrical measuring resistor to mutually opposed regions of the electrical measuring resistor and the electrical shield resistor.
