The Ranger EXP offers maximum performance
in a lightweight, rugged solution for using your
survey meter in the eld. The Ranger EXP is designed
specically 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!
Detector
RAP-RS2 Probe - External Halogen-quenched,
uncompensated GM tube with thin mica window,
1.4-2.0 mg/cm2 areal density. Effective diameter of
window is 45 mm (1.75 in.).
Operating Range
mR/hr - .001 (1µR) to 100 CPM - 0 to 350,000
µSv/hr - .01 to 1000 CPS - 0 to 5000
Total/Timer - 1 to 9,999,000 counts
Accuracy
(Referenced to Cs137) Typically ±15% from factory,
±10% with NIST Source Calibration
Energy Sensitivity
3340 CPM/mR/hr referenced to Cs
• Detects Alpha down to 2 MeV.
• Detects Beta down to .16 MeV; typical detection
efciency at 1 MeV is approx. 25%.
• Detects Gamma down to 10 KeV through the detector
window.
• Smallest detectable level for I
contact.
