  • Product Description

    The Ranger EXP is the external probe model of the Ranger "pocket" Geiger counter, where essentially, the sensor or Geiger-Mueller tube, is relocated from the Ranger's "pocket" model enclosure to the end of a wand-style probe instead, connected to the base survey meter with a probe cable.

    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!

    Specifications 

    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 Counts- 1 to 9,999,000 counts Accuracy (Referenced to Cs137)     Typically ±15% from factory, ±10% with NIST Source 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 through the detector window. Gamma Sensitivity is 3340 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.Energy Response Curve                

    Built-In Efficiencies

    Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha

    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 Software Family

    Power Requirements

    Two AA alkaline batteries (included)

    Size

    140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)     Probe: 260 X 70 X 25 mm (10.25 X 2.75 X 1 in.)

     

    Probe Cable

    The cable connecting the meter to the probe is a full 36" long, while the probe handle itself is 10" long, allowing for detection at a distance, thus reducing the chance of contamination of hands or gloves while scanning and frisking.

    Includes

    Carrying Case, Xtreme Boot, Stand, Mini-USB Cable, Observer USB Software Download, Certificate of Conformance

    Options

    NIST Calibration

    Limited Warranty

    1 year limited warranty
