When choosing an explosion-proof radiation measuring instrument suitable for your own use, you need to consider these aspects

The working principle of explosion-proof radiation measuring instruments is similar to that of ordinary radiation measuring instruments. It mainly senses the radiation dose or intensity in the environment through detectors. The detector converts the received radiation signal into an electrical signal, which is then processed, recorded and analyzed by electronic equipment. The difference is that special explosion-proof measures are adopted between the detector and the electronic equipment to ensure normal operation in hazardous environments. When choosing an explosion-proof radiation measuring instrument for your own use, there are a few key aspects to consider to ensure that the instrument you choose meets your specific needs.
