INTRODUCTION
The Model 451B state-of-the-art ion chamber survey meter is a hand-held battery operated unit designed for use in both rugged and normal environments. The
Model 45 1B measures alpha, beta, gamma and X-ray radiation. The Model 45 1B employs microprocessor and LCD technology and features a rugged ionization chamber with a mylar window and protective steel mesh. An integral beta shield serves as an equilibrium thickness for photon measurements. The ergonomic handle, features a large diameter cushioned grip and is designed to reduce fatigue associated with extended use. The case is constructed of lightweight, high strength materials and is sealed against moisture. The user must specify R or Sv when ordering.The display features an analog bar graph, 2 1/2 digit digital readout, low battery
and freeze mode indicators. User controls consist of an ON/OFF button and a
MODE button. The unit is auto-zeroing and auto-ranging. The display features
circuitry that automatically activates the backlight in low ambient light conditions.The RS-232 interface can be connected directly to a computer for use with the ' Freeze indicates peak reading Excel add-in for Windows®, enhancing the functionality of the instrument. The software allows for data retrieval, user parameter selection and provides a virtual instrument display with audible (requires sound card) and visual alarm indication. The software may be customized by the user for specific applications.
