Item, hammer seat, venthole, moisture separator, drainage hole, drier, sponge plug, desiccant portal, desiccant into hole, gas vent and
Plastic catheter, the gravel filter hole of air inlet pipe outer wall may filter that the ground block of greater particle size, the separable sandy soil built in air inlet pipe
Filtration net cover can filter the grains of sand and soil of different-grain diameter again, and leakproof gas hood is screwed and is buckled on ground by adjusting
To prevent the leakage of radon gas, the drainage hole of switch moisture separator bottom separates the water in sampler, switchs drier bottom
Desiccant portal fast changeable desiccant.
The utility model has the beneficial effects that the utility model operation mode, is arranged gravel by air inlet pipe outer wall and filters
Hole and the built-in double-deck separable sandy soil filtration net cover, may filter that the rock, the grains of sand and soil of different-grain diameter to solve sampler
Adjustable leakproof gas hood is arranged to solve the leakage of radon gas in radon gas cross contamination and soil in soil and air in blockage problem
Problem, moisture separator can facilitate water in discharge sampler, and drier bottom setting desiccant portals fast changeable desiccant.
