Radiation Survey Meter – NXG [ TYPE : RM751]
Technical Data

RADIATION SURVEY METER- NXG Type: RM751 is a next generation, Compact Series, Radiation Survey Meter. It is, Primarily a G.M. Detector based, battery powered, hand-held, ruggedized general-purpose radiation Survey Meter. This will be useful for dose & dose rate measurements in Nuclear installations, Radiochemical plants, Reprocessing plants, Radiotherapy depts, Nuclear medicine centres etc. Additionally, it will be useful in industrial and other installations where radioactive sources are used for a variety of applications.
This product is designed around a low power Micro-controller Chip. It is provided with a Graphic LCD display for indicating the dose-rate, cumulative dose etc. It covers wide range from 0.01mR/hr to 10R/hr with auto ranging. This unit has a facility for storing the data into built-in flash memory along with time stamp. The stored data can be retrieved to PC, or mobile Via USB or Blue-tooth. Also, Readings can be displayed on graphic LCD.Features
