The Fluke 481 DESI Ion Chamber Survey Meter is a radiation meter used by emergency response professionals, inspectors, HAZMAT teams, and nuclear power workers to detect skin-dose (beta particle), deep-dose (gamma), and x-ray radioactivity. It measures dose and dose rate and can be used to identify irradiated goods, equipment, surfaces, and environments, improve worker safety, and maintain compliance with regulations.
Auto-ranging capabilities ensure the Fluke 481 DESI Ion Chamber Survey Meter provides prompt, precise readings; it is 30% more accurate than other radiation meters available on the market.
This rugged instrument with a sealed case, automated backlight, and a simple, two-button operating system, is ideal for use indoors and outdoors, on industrial sites, and in areas with low light. The Fluke 481 DESI Ion Chamber Survey Meter’s two 9V batteries deliver over a week of operation. It is a portable, practical, and precise radiation meter suitable for contamination detection, general radiation area metering, radiation level monitoring, and hazardous materials assessment.
