  • Product Description

    The Ranger EXP is the external probe model of the Ranger "pocket" Geiger counter, where essentially, the sensor or Geiger-Mueller (GM) 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 tough industrial environments in the lab or in the field.  With its oversized, pancake style GM tube, it offers excellent sensitivity to low levels of Alpha, Beta, as well as Gamma and X-raysThe EXP's survey meter is now smaller, more ergonomic, and with better features, all for the same price!  The Ranger EXP features a new interface with touchpad technology, and included with each instrument at no extra charge is an integrated, protective boot.  Other features:  

     

    • Small, handheld, microprocessor-based instrument
    • Excellent sensitivity to low levels of Alpha, Beta, Gamma, and X-rays
    • Backlit digital display
    • Red count light
    • Audible Beeper that sounds with each count detected, providing instant indications of the radiation level.
    • Selectable alert levels
    • Adjustable timer for performing Timed Counts
    • Built in efficiencies for common isotopes to calculate activity in Bq and DPM. (Important: The Ranger does not identify isotopes - to use this feature,  you must know the isotope in advance).
    • Internal memory, data logging, and USB connectivity
    • Free Observer USB Software to download your data, set computer alarms, and calibrate your instrument!

      

    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
