PingdingshanHigh-sensitivity environmental radon detector
Product Description
Features:
● This instrument uses a bidirectional detector structure and a thin film material that allows α rays to penetrate as a sampler, thus forming a near 4π measurement condition. This technology can increase the detection efficiency of the instrument to 4 times that of single-sided detection. ；
● Electric field adsorption is used for sampling. When used for indoor measurements, this technology makes the equivalent sampling volume of the sampler reach tens of liters; the above two technologies make the instrument sensitivity several to hundreds of times higher than that of common similar instruments, so satisfactory measurement accuracy can be obtained in low ；
● radon concentration situations. This instrument can measure indoor radon, soil radon, and radon in water concentration and radon emanation
● rate measurement; During the measurement process, the detector is not contaminated. During continuous measurement, the average time to complete a sampling-measurement process is no more than 25min, therefore satisfactory work efficiency can be obtained. For soil radon measurement, the average time from sampling to completion of measurement at one measuring point is no more than 5min;
● The instrument has a compact and reasonable structure, small size, light weight, easy to carry, simple operation, and fast results. The instrument has a built-in power supply system and is not affected by power supply conditions. 响。
