451P-RYR Pressurized Ion Chamber Survey Meter, Radiation Detector

The FLUKE BIOMEDICAL 451P-RYR Pressurized µR Ion Chamber Survey Meter is a handheld digital radiation detection instrument designed to measure gamma, X-ray, and beta radiation exposure levels. It features a pressurized ion chamber that provides stable, precise readings across a wide energy range starting from 25 keV for gamma and X-rays, and 1 keV for beta radiation. The meter offers digital and analog display options on a backlit LCD and supports multiple measuring units, including mR/hr, mSv/hr, R/hr, µSv/hr, and µR/hr. Powered by two 9V alkaline batteries, it provides up to 200 hours of continuous operation and includes a chamber and NIST calibration certificate.
