A dedicated data acquisition and monitors system for measuring the response times of gas sensors

For measuring the gas sensors response and recovery times a complex system was built. The gas concentration under the steady-state conditions is varied through a dilution system. We have demonstrated the feasibility of using an interactive program and an electronic system to study the response speed for gas sensors in multiple gas mixture. The system is generally enough to be extended to measurable parameters specific for gas sensors (EMF, R,I).
