The radiation detector DT-9501 was developed to detect α-, β-, γ- and x- radiation. The radiation meter DT-9501 provides many features including a large, high-resolution backlit LCD display with annunciators. The radiation detector DT-9501 has internal data storage for up to 2000 data sets, which are saved either manually or automatically. Furthermore the radiation detector DT-9501 is equipped with a Bluetooth interface to transfer the measured data in real-time to a computer. With the software, that is included with the product, the data can then be further processed and reviewed. The radiation detector DT-9501 stands out with its high accuracy and practical design. The radiation detector can be applied in the pharmaceutical industry, laboratories, power plants, quarries, the emergency services, metal industries, petroleum reservoirs, environmental protection etc.
