Brief introduction: This analyzer which is also called indoor emanation analyzer, used with scaler to measure radioactive elements uranium and thorium the emanation of the sample, also can be used for determination of water samples and the concentration of the trace radon emanation in tunnel. Scintillation chamber is two internal coated ZnS (Ag) administered organic glass scintillator hemisphere, disk can install three scintillation chamber at the same time, one is located in the top of the photomultiplier tube, are measured scintillation chamber, the other two is in dark state, waiting for the measurement, using the handle to change the location of the scintillation chamber on the disk, so that we can under the condition of non-stop, continuous replacement scintillation chamber samples, until your measurements. Technical indicators: A laser measuring time: 100 s. Scintillation chamber radium coefficient: about 1.4 x 10 to 13 gra/pulse. Thorium measurement time: 300 s Scintillation chamber inherent background: no more than 100 count s - 1. Flat scintillation chamber seal: ten minutes is not more than 1.33 x 103 pa (10 MMHG). Measuring plate: can install three scintillation chamber at the same time, under the condition of non-stop, continuous measurement. Repeated measurement error: no more than plus or minus 10%. Working temperature: 20 + / - 5 ℃, Relative humidity: 65 + / - 5%; Power supply: power supply by an external supply, the amplifier is + 9 v ~ 10 v Photomultiplier tube power supply: 0 ~ 1500 v adjustable negative dc high voltage. Instrument weight: 16 kg
