The Fluke 481 Radiation Survey Meter is a portable and practical means for discovering irradiated goods, equipment, surfaces or environments in industrial settings. Use of the device reassures employees that radiation risks are known, monitored and measured for their protection. If radiation is found, a clear and quantifiable result allows managers to comply with federal guidelines, without overreacting with unnecessary steps that might halt operations, impact productivity or lead to lost revenue.

The Fluke 481 Radiation Survey Meter detects beta, gamma and X-ray radioactivity and provides prompt readings of dose and dose-rate. The rugged meter requires no adjustments and utilizes a simple two button interface. The LCD display includes a 100 element bar graph as well as a 2.5 digital readout that displays the measurement at all times. The 481 is accurate to ±10% of full scale indication—nearly 30% better than comparable meters. The 481 includes auto-zeroing, auto-ranging, and auto-backlight functions.

Detects skin-dose (beta particle) and deep-dose (gamma) and X-ray radioactivity
Requires no adjustments; simple two button process
Provides promptly read, correct value through autoranging capability
Easily visible inside truck trailers and other low-light situations with automated backlight
Works dependably inside or outside thanks to sealed case
30% more precise than other available meters
Delivers more than one week of uninterrupted functioning with 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
Valuable for contamination-detection, general radiation area metering, radiation-level monitoring, and hazardous materials assessment
Rugged Fluke design

Analog    100 element bar graph 6.4 cm long. Bar graph is divided into 5 major segments, each labeled with the appropriate value for the range of the instrument
Digital    2.5 digit display is followed by a significant zero digit depending on the operating range of the instrument. The units of measurement are indicated on the display at all times
Integrated mode    Operates continuously 30 seconds after the instrument has been turned on. Integration is performed even if the instrument is displaying in mR/h or R/h
Freeze mode    Will place a tick mark on the bar graph display to hold on the peak displayed value. The unit will continue to read and display current radiation values
