Description
The Neutron Module Hp(10) is an operational dosimetry solution for environments with neutron radiation risks. It attaches to the DMC 3000 dosimeter, enabling the measurement of Hp(10) radiation across a wide spectrum of energy levels. The neutron measurements, dose rates, and associated alarms are clearly displayed on the DMC 3000's high-contrast backlit LCD and indicated by its LEDs.
The module is powered directly by the DMC 3000, eliminating the need for a separate battery. It offers extended operational life, lasting over 2400 hours of continuous use. Calibration data and functional parameters are securely stored within the module itself.
