Technical Data
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 auto-ranges
and measures radiation rate and accumulated
dose from various radiation sources (beta, 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.
The digital display features an analog bar graph,
2.5 digit readout, low battery indicator, freeze
(peak hold) mode indicator and an automatic back-
light 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.
