Product Instruction
EI-R101 is a new environmental grade X-ray and gamma radiation dose equivalent (rate) meter. The system consists of a highly sensitive composite scintillator detector and a mainframe unit with excellent energy response and radiation response performance, accurate dose equivalent measurements and a rapid response to slight increases in radiation levels.
Functional Features
– Large volume composite scintillator detector with built-in GM tube and wide energy response
– High sensitivity and fast response to weak radioactivity
– Automatic high and low range switching function, continuously adjustable dose and dose rate alarm thresholds
– Large LCD display with manual or automatic sensing of the backlight
– Waterproof and wear-resistant aluminum housing, corrosion-resistant, protection class IP66
– Optional special tripod for outdoor spot monitoring
Application Areas
– Homeland Security | – Nuclear Emergency Response | – Environmental monitoring |
– Nuclear power plants | – CDC and health surveillance agencies | – Nuclear-related fields |
