[0008] However, in the conventional detection devices as described above, a plurality of detection devices are directly installed at a plurality of combustion points in the gas pipeline to sample the sample gas. Therefore, the same number of gas detection devices as the number of detection points required device, so there is a potential waste of installation price (cost), installation space, installation time, etc.
[0009] Moreover, as mentioned above, the gas detection device with one gas chamber needs to selectively allow the gas to flow between the sampling tube and the gas chamber through the valve. At this time, there is a lot of delay in the process of completely removing the inhaled gas. a matter of time

The present invention relates to a gas measurement device with a multi-gas cell structure for multi-point measurement for measuring multi-point sampling gas by using a gas measurement device having alight source, a gas cell, and a detector. The present invention comprises the gas cell in which the light source and sample gas such as standard gas or exhaust gas pass through and one detector is arranged in a line on an optical path. The gas cell comprises a multi-gas cell in which the plurality of gas cells are arranged side by side so as to be parallel to the optical path. Each of the gas cells has a gas inlet and a gas outlet, separately. And the sample gas such as the standard gas and the exhaust gas is configured to pass through the inside of the cell. Therefore, price (cost), space, measurement time, and the like can be reduced.
Description
technical field [0001] The present invention relates to a gas detection device with a multi-gas chamber structure for multi-point detection, and in more detail, to a gas detection device with a multi-gas chamber structure for multi-point detection as follows: having a light source, a In a gas detection device with a gas cell and a single detector, the gas cell structure is composed of a multi-gas cell structure in which a plurality of gases pass through in stages with a time difference. , after the light emitted from one light source is incident on the inside of the gas chamber step by step with a time difference, the calculation process can be performed step by step with a time difference at a detector, thereby saving the price (cost) , space, detection time, etc. Background technique [0002] Generally, conventional gas detection devices are in the form of a gas cell and a detector on the path of light emitted from a light source, such as figure 1 As illustrated, the abo...
