Double flow path anti-interference flowable sample pool

The utility model discloses a double flow path anti-interference flowable sample pool comprising an internal and external pool including internal and external two pipe bodies. The double flow path anti-interference flowable sample pool is installed in flow of production matching with optic block and can resist the disturbance to analysis from air bubbles and precipitates, and has the advantages of convenient maintenance after disposable installing and non-substitute part constantly and non-other maintenance. Compared with the present method which draws the sample from production line depending on a pump and analyses the sample or eliminates the precipitates depending on a filter membrane, the cost of the disposable mounting of the utility model can drop down more than one half and the utility model can relief or reduce maintenance, and the cost of extended service is less than 20 percent of classical methods.
