Abstract: A gas detection system utilizing an ionic gas detector having an extended range of sensitivity adjustment obtained by signal and sample attenuation. Signal attenuation adjustment is obtained by use of a voltage divider in the detector output circuit. Sample attenuation is obtained by adjusting the ratio of sample and diluent gases with control valves and calibrated orifices. Both adjustments are made with a single sensitivity controller.
