Personal Radiation Detector


lead time: usually 4-8 weeks

This portable radiation detector is especially useful for professionals dealing with security of public areas, border control and sensitive installations. The portable radiation detector is used to detect the presence and intensity of gamma radiation. The MER11 personal radiation detector is lightweight, compact and sensitive, making it an easy-to-use portable radiation detector. The MER11 is designed to meet the ANSI N42.32 and 42.33 radiation detection requirements.

We have integrated state-of-the-art electronic components to provide a high-quality personal radiation detector. One of the advanced technologies we have integrated the use of silicon photomultipliers as detector.

This personal radiation detector is easy-to-use due to the utilization of an extra display on the top side of the detector. Current presence and intensity of radiation can be seen on the top side while it is carried on the user belt. The top side provides clear and simple indication, while still allowing further complimentary information on the front LCD while pulled out of the user belt.
