Fluke 481 Radiation Survey Meter
The Fluke 481 Radiation Survey Meter is a portable and practical means for identifying irradiated goods equipment, surfaces or environments in industrial settings, for ensuring worker safety
Detects skin-dose (beta particle) and deep-dose (gamma) and X-ray radiation
Requires no adjustments; simple two button operation
Delivers quickly read, correct value through autoranging capability
Easily visible inside truck trailers and other low-light conditions with automated backlight
Works reliably indoors or outdoors thanks to sealed case
Delivers more than one week of continuous operation from two 9-volt alkaline batteries
Proven in use by state and local governmental emergency response professionals, state inspectors, HAZMAT teams and nuclear power workers
Measures both dose and dose-rate
Useful for contamination-detection, general radiation area surveys, radiation-level monitoring, and hazardous materials assessment
Ruggedized Fluke design
