Dose Rate Meter

·         The NEB.211 Dose-Rate Meter is an excellent multi-purpose portable radiation meter designed for wide range of applications. It fits in the palm of the hand. It is convenient to be used in Health Physics Applications, Industrial Radiography, Gamma Radiation and Sterilization Institutions, Isotope Applications Laboratories, in industrial radioactivity applications and in civil defense.

·         Micro controller enables reliable, stable radiation measurement, especially in low level dose rate fields. It makes possible to measure both dose rate and dose values simultaneously.

·         The dose or dose rate alarm level can be set in steps within the full measurement range.  If adjusted alarm level exceeded, it warns audibly.

·         NEB.211 incorporates an acoustic generator for audible indication of single pulses, which is suitable for tracing low-level radioactivity.

·         The dose or dose rate alarm level can be set in steps within the full measurement range.

·         The instrument has also self test facility. The display shows the defects.
