The 451B state-of-the-art ion chamber survey meter is a handheld battery operated unit designed for use in both rugged and normal environments. The 451B includes a sliding beta shield to serve as an equilibrium thickness for photon measurements and enables beta discrimination. The 451B auto-ranges and measures radiation rate and accumulated dose from various radiation sources (alpha, beta, x-ray, 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.
The digital display features an analog bar graph, 2.5 digit readout, low battery indicator, freeze (peak hold) mode indicator, and an automatic backlight function. User controls consist of an ON/OFF button and a MODE button. The case is constructed of lightweight, high strength materials and is sealed against moisture.
The RS-232 interface can be connected directly to a computer for use with the Excel add-in for Windows (451EXL), enhancing the functionality of the instrument. This software allows for data retrieval, user parameter selection and provides a virtual instrument display with audible and visual alarm indication.
Key features:
• Measures skin dose (slide open) and deep dose (slide closed)
• High sensitivity measurement of rate and dose simultaneously
• Records peak rate using “Freeze Mode”
• Auto-ranging and auto-zeroing
• RS-232 communications interface with optional Windows-based Excel add-in for data logging • Ergonomic, anti-fatigue handle with replaceable grip, wrist strap and tripod mount
• Programmable flashing LCD display
• Easily-accessible battery door (operated by two 9-volt alkaline batteries) on the outside of the bottom case
• Available with dose equivalent energy response (SI units)
