Take gamma spectrometer sample test frame of self -cleaning function

The utility model relates to a take gamma spectrometer sample test frame of self -cleaning function, the gamma spectrometer sample test frame structure of having overcome prior art is too simple and easy, very impracticable, especially can not overcome the gamma spectrometer sample can surface dewfall that hazes, influences the probe and the inner chamber of gamma spectrometer, causes the defect of pollution. Include last base and lower base, go up the base and pass through the height regulating mechanism connection with lower base that there is the through -hole at the center of lower base, the diameter of through -hole and the probe external diameter looks adaptation of gamma spectrometer, upward there is the thru hole that can directly penetrate gamma light at the base center, and the periphery that goes up the base is connected with the temperature isolation layer, and the internal diameter of temperature isolation layer is greater than the external diameter of gamma spectrometer sample can. The utility model has the advantages of the haze accurate convenience of distance adjustment of dewfall, gamma spectrometer sample can and probe of gamma spectrometer sample can surface is avoided to the temperature isolation layer.
