IMI Rad 100 Description：

Product Manual Datasheet

The RAD 100? is a professional general purpose radiation survey meter/geiger counter that detects and measures alpha, beta, gamma, and X-radiation. It is intended for personal safety, workplace and environmental safety and scientific purposes. First Responders and industrial workers appreciate the tactile switches, which can be operated with work or safety gloves. Like the popular Radalert® 100X, the RAD 100? features a 3-second update on its large and easily readable liquid crystal display (LCD). The LCD displays the current radiation level in your choice of μSv/h (microSieverts per hour) (SI units) or mR/hr – for gamma radiation measurements. For mixed sources (alpha, beta, gamma) the CPM mode is recommended. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours for analysis of samples and detection of subtle radiation level changes. A red LED blinks and a beeper chirps with each count (the chirp can be muted). This is a professional instrument that is also easy to learn to use and to operate, and carries the industry leading Medcom warranty (2 years overall limited to 1 year on the GM sensor). Many instruments designed by the Medcom team are still working perfectly after 35 years of use, so with proper care this instrument should provide a lifetime of useful service. For rugged workplace environments the optional multi purpose Protect® Boot provides an extra level of protection, a magnetic belt clip, and a tilt stand.
