    Detailed Product Description

    General Purpose Ratemeter

     

    Features
    • Low Price
    • Rugged
    • 5-Decade Analog Ratemeter
    • Operates Two Detectors
    - Built-in Internal GM Detector
    - External GM or Scintillator Detector

     

    Introduction
    The general purpose, handheld analog ratemeter supports operating two separate radiation detectors.
    This instrument is set for 900-volt GM tube operation and is typically used with an external, thin-wall GM tube
    or pancake GM. Other external detectors are compatible. An internal energy-compensated, high-range
    detector is used for the x10000 range only. This detector is active whenever the instrument is on and in a
    very high radiation feld, and it will drive the meter needle to full scale, thus alerting the user.
    A switch allows the operator to select between the internally mounted GM detector with an exposure
    range of 0 to 20 mSv/h (0 to 2000 mR/hr) or an external GM or scintillator detector of choice

     

    Specifcations

    APPLICATION: alpha, beta, gamma survey
    COMPATIBLE DETECTORS: GM, scintillation
    DETECTOR CHANNELS : x0.1 through x100 range settings read out the external detector channel, x1000 reads out the internal GM detector
    EXTERNAL DETECTOR: any GM or scintillator operating on 900 Vdc
    INTERNAL DETECTOR : energy compensated GM, 0–20 mSv/h (0–2000 mR/hr), used with x1000 scale only
    ENERGY RESPONSE: within 15% of true value between 60 keV–3 MeV (internal detector only)
    LINEARITY: reading within 10% of true value with detector connected
    HIGH VOLTAGE: 900 volts
    THRESHOLD: -40 mV ±10 mV
    CONNECTOR : series “C”
    METER : 6.4 cm (2.5 in.) arc, 1 mA analog type
    METER DIAL: typically 0–2 mR/hr and cpm, BAT TEST (others available)

     

    CONTROLS:
    Rotary Selector Switch: switches instrument to Off or ranges: x0.1, x1, x10, x100 x1000
    Response Switch: toggles between FAST (4 seconds) or SLOW (22 seconds) from 10% to 90% of fnal reading
    Reset Pushbutton: to zero meter
    Battery Pushbutton: checks battery status
    Audio Switch: audio on/off, built-in unimorph speaker, greater than 60 dB at 0.6 meters (2 ft)

     

    POWER: 2 each “D” cell batteries (housed in an externally accessible sealed compartment)

    BATTERY LIFE : typically greater than 2000 hrs (battery condition can be checked on meter); LOW BAT warning

    CONSTRUCTION: cast and drawn aluminum with beige powder coating

    TEMPERATURE RANGE : -20 to 50 °C (-4 to 122 °F)

    RELATIVE HUMIDITY: < 95%
    SIZE: 16.5 x 8.9 x 21.6 cm (6.5 x 3.5 x 8.5 in.) (H x W x D)
    WEIGHT : 1.6 kg (3.5 lb), including batteries
