  • Product Description

    The 'Radiation Alert' Ranger Pocket Geiger Counter is now smaller, more ergonomic, and with better features, all for the same price!  The Ranger features a new interface with touchpad technology.  Included with each instrument for no extra charge is a protective boot, carrying case and stand that holds the instrument upright for hands-free operation!

    The Ranger offers maximum performance in a lightweight, rugged solution for surveying at the facility or in the field. The Ranger has been designed for industrial environments, but it still has all of the features you’ve come to love in the lab. 

     

    • 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!
    • Optional wipe test plate for swipes.

     

     Specifications

     

    Detector

     

        Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.77 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. 3340 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.                 

     

    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 - 50 and CPM 1 - 160,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. 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 Display 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 for PCs

     

    Power Requirements

     

        Two AA alkaline batteries (included)

     

    Size

     

        140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)

     

    Includes

     

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

     

    Options

     

    Wipe Test Plate, Swipes, NIST Calibration

     

    Limited Warranty

     

    1 year limited warranty
