Product Instruction
EI-R111 Neutron and Gamma Rate Survey Meter is a new handheld radiation survey meter that detects both neutrons and gamma rays. The neutron detector is wrapped with a unique spherical column-shaped slowing body, which features high neutron detection sensitivity, good suppression of interfering gamma radiation fields, miniaturisation, digitalisation and intelligence. It can be used handheld or worn for neutron, x and gamma radiation level measurement and search, etc.
Functional features
– Free switching between count rate, dose rate and cumulative dose
– HD black and white display with manually illuminated backlight
– Independent gamma and neutron measurement channels and alarm alerts
– Continuously adjustable alarm thresholds, audible, visual and iconic alarms at the same time
Application areas
– Radiation protection of nuclear facilities, nuclear regulatory and source-related enterprises and institutions
– Environmental monitoring department for official duties, disease control and health department for emergency response
– Security precautions for major events, embassies and consulates abroad
– Customs, border control and other nuclear and radiological counter-terrorism, prevention of illegal radioactive material transport and radiological terrorist attacks, etc.
– Third party testing agencies
