The
Ranger EXP
offers maximum
performance in a
lightweight, rugged
solution for using
your survey meter in
the field. The
Ranger EXP is
designed
specifically for
individuals
operating in tough
environments. The
small, handheld unit
offers excellent
sensitivity to low
levels of alpha,
beta, gamma, and
x-rays. The digital
readout is displayed
with a red count
light and a beeper
sounds with each
count detected.
Other features
include an
adjustable timer,
selectable alert,
and with the free
Observer USB
Software Family, you
can download your
collected data, set
alarms, and
calibrate your
meter!

Calibration
Energy Sensitivity
Detects Alpha down
to 2 MeV. Detects
Beta down to .16 MeV;
typical detection
efficiency at 1 MeV
is
approx. 25%. Detects
Gamma down to 10 KeV

Selectable Alert Set
Range
mR/hr .001 - 100 and
CPM 1 - 350,000.
70db @ 1m. Pulsating
beeper sounds the
alert. Adjustable
alert levels are
used for mR/hr / CPM,
and µSv/hr / CPS.
Alarm will sound
when in Timer Mode
when set alarm
threshold is
reached.
Anti-Saturation
Meter will hold at
OVER RANGE in fields
as high as 100 times
the maximum reading.
Averaging
Periods
Display updates
every 3 seconds. At
low background
levels, the update
is the average for
the past 30-second
time period. The
timed period for the
average decreases as
the radiation level
increases.
Display
Graphic LCD with
Backlight
Count Light
Red LED flashes with
each radiation
event.
Audio Indicator
Internally mounted
beeper (can be
switched off for
silent operation)
Outputs
USB for use with
Free Observer USB
