Portable testing device for gas sensor

摘要

The device includes a container (1) filled with a gas suitable to be detected by the sensor being tested and connected to a balloon (6). The gas is transferred into the balloon where it reaches the room temperature and a low pressure. A diffuser (8) is attached to the balloon output and coupled to the gas sensor thus ensuring dispersion of the gas over the sensor. If the sensor is functional is should detect the gas and generate a signal.
