Abstract
An inspection apparatus for gas detectors is disclosed which comprises an open-feasibly air-tight testing reservoir in which gas detectors to be tested can be positioned, an air-tight dispensing reservoir for mixing the gas to be tested, a vacuum device for making the testing reservoir and the dispensing reservoir in vacuum, a gas supply device for supplying at least a standard gas and a diluting gas to the dispensing reservoir, and a controlling means for controlling the dispensation of the gases to each of the above-described components of the invention. By means of the invention, the executions of the mixing of the gases and the detection of the gas detector are substantially simultaneous and thus the time consumption as well as the amount of required gas are reduced. Moreover, an automatic control is available when the inspection apparatus of the invention is equipped with a computer.
