A portable type TSP sampler is designed according to the market demand. The sam-pler uses STC12C5A60S2,an enhanced 51 core SCM as controller,customized section type large screen LCD as displayer. Automatic constant flow sampling is achieved with using the chip of HX711,a 24 bit A/D converter,and M1210,a differential pressure sensor,and uses the flow dif-ferential signal to control the air pump.
