451P microR Ion Chamber Survey Meter | Fluke Biomedical

General Description
The 451P state-of-the-art ion chamber survey meter is a handheld battery operated unit designed for use in both rugged and normal environments. The 451P is a pressurized ion chamber for μR resolution. The 451P has auto-ranging and measure radiation rate and accumulated dose from various radiation sources (x-ray and gamma). The ion chamber detector allows for a fast response time to radiation from leakage, scatter beams, and pinholes. Additionally, the low-noise chamber bias supply provides for fast background-settling time.

Technical Description
Pressurized ion chamber technology.
