The Fluke 481 Radiation Detection Meter is a portable and practical means for discovering irradiated goods, and for helping remediate contaminant and safety issues while minimally affecting performances. Ideal for detecting irradiated goods, equipment, surfaces or environments in industrial settings, the 481 Radiation Meter helps ascertain worker safety and compliance to federal regulations.
Use of the Fluke 481 Radiation Survey Meter assures employees that radiation dangers are known, monitored and calculated for their security. Whenever radiation is found, a clear and quantifiable result provides handlers to comply with federal guidelines while avoiding unnecessary steps that could stop procedures, impact productivity or lead to missed revenue. A clear and quantifiable result from the Fluke 481 Radiation Detection Meter 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/Detection Meter is ideal for detecting irradiated goods, equipment, surfaces or environments in industrial settings, for ensuring worker safety and complying with federal regulations.

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. Digits are 6.4 mm (0.25 in) high. Low battery and freeze indicators are also provided on the display |
| Modes |
Integrate 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 |
