Sper Scientific 840024 Digital Radiation Meter - Manual (Page 4)

- 4 -
This manual provides the necessary
information for proper use and care of
Sper Scientific Model 840024 Radiation
Meter. We recommend reading this
manual completely prior to using the
instrument. It also contains valuable
information about the nature of ionizing
radiation that should be understood by
the user so that accurate measurements
can be made.
This Radiation Meter features selectable
measurement scales, adjustable audible
alarm and auto power off. It uses a thin
wall glass Geiger-Mueller (GM) tube that
will detect Beta and Gamma ionizing
radiation and X-rays. The GM tube
generates an electrical pulse each time
radiation passes through the tube.
These pulses are then electronically
detected and displayed in either SI units
(micro-sieverts per hour) or conventional
units (milliroentgens per hour).
