Pressurized µR Ion Chamber Survey Meter

harpell — Thu, 10 Dec 2009 01:08:51 +0000

The auto-ranging 451P features a pressurized ion chamber, providing enhanced sensitivity (µR resolution) and improved energy response to measure radiation rate and dose from x-ray and gamma sources. Originally designed to measure leakage and scatter around diagnostic x-ray and radiation therapy suites, the 451P’s site surveying capabilities make it well-suited for a wide range of end users, including: x-ray manufacturers, government
agencies, state inspectors, biomedical technicians, and maintenance technicians for airport baggage scanners. 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 digital readout, low battery and freeze (“peak hold”) mode indicators, 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 (requires sound card) and visual alarm indication.

Features:

High sensitivity µR measurements of rate and dose simultaneously, with the capability to record peak rate
Ergonomic, anti-fatigue handle with replaceable grip, wrist strap and tripod mount
Programmable flashing LCD display and audible alarm
Easily-accessible battery door (operated by two 9-volt alkaline batteries) on the outside of the bottom case
RS-232 communications interface with optional Windows-based Excel add-in for data logging
Available with dose equivalent energy response (SI units)

The 451EXL provides remote control for many of the 451B and 451P functions via a Microsoft® Excel-based user interface, including real-time data logging with user defined alarm parameters, upload of the internal data log into Excel worksheet, real-time virtual instrument display, and accumulated dose measurement over a user defined integration period. This information management software is ideal for the facility Radiation Safety Officer or anyone responsible for maintaining a permanent record of spills and accidents for adherence to state and NRC requirements.

The 451EXL’s data logging function automatically records real-time measured data into an Excel worksheet. The 451 Assistant provides user configurable audible and visual alarms for the real time logged data, including the color-coding of each data entry for quick identification for radiation levels and alarm acknowledgment status. This 451EXL information management software program is ideal for the facility radiation safety officer or anyone responsible for maintaining a permanent record of spills and accidents for adherence to state and NRC requirements.

Features:

Real time data logging and uploading of 451 internal data log into protected Excel worksheet
Virtual instrument display with user-defined audible and visual alarm indication
Compatible with Windows® 2000 and above, and Excel 97, 2000
Package includes manual, diskette set, and 25 ft RS-232 cable, Model 1020039000
