STATE OF ART INSTRUMENTATION FROM AN INNOVATIVE COMPANY

RADIATION SURVEY METER [ Type : RM 701N ]

 
Technical Data

RADIATION SURVEY METER (micro) Type: RM701N is a G.M. Detector based, battery powered, hand-held, ruggedized general purpose radiation Survey Meter. This will be useful for dose rate measurements in Nuclear installations, Radiochemical plants, Reprocessing plants, etc. Additionally it will be useful in medical, agricultural, industrial and other installations where radioactive isotopes are used for a variety of applications.

This product is designed around a Microcontroller Chip. It is provided with alpha Numeric LCD display for indicating the doserate in digits, dose rate as a bar graph, cumulative dose in digits. It covers wide range from 0 to 10R/hr in two range with auto ranging. This unit has a facility for storing the data into built-in E2PROM along with real time. The stored data can be recalled on to the display or transmitted to PC through USB port.
