  • Description

    The Model 375 Digital Wall-Mount Area Monitor is designed for visibility and ease of use. This monitor incorporates an internal energy compensated GM detector with a range from 1 µSv/h to 10 mS/h (0.1 mR/hr to 1 R/hr).

    It features a wall-mount chassis and a four-digit LED display that is readable from 30 feet. Backlit indicators warn of low radiation (yellow), high radiation (red), instrument failure (red), and low battery (yellow), along with an alarm. A green status light is a positive indication of instrument operation.

     

    INDICATED USE: gamma monitoring
    COMPATIBLE DETECTORS: GM, proportional, and scintillation
    DISPLAY: 4-digit LED display with 2 cm (0.8 in.) character height
    DISPLAY RANGE: 000.0 to 9999 (Series One: 00.00 to 9999)
    OPERATING RANGE: 1 μSv/h to 10 mSv/h (0.1 mR/hr to 1 R/hr)
    DISPLAY UNITS: can be made to display in μR/hr, mR/hr, R/hr, μSv/h, mSv/h, Sv/h, μrem/hr, mrem/hr, rem/hr, cpm, cps, and others
    LINEARITY: readings within 10% of true value with detector connected
    RESPONSE: typically 3 seconds from 10% to 90% of final reading
    INDICATORS:

    • STATUS: (green light) instrument functioning properly
    • LOW ALARM: (yellow light and slow [1 per second] beep) can be set at any point from 0.0 to 9999
    • HIGH ALARM: (red light and fast [4 per second] beep) can be set at any point from 0.0 to 9999
    • DET FAIL: (red light and audible tone) for conditions of detector overload, no count from detector, or instrument failure
    • LOW BAT: (yellow light) indicates less than 2 hours of battery power remaining
    • OVERLOAD: display reading of -OL- and audible FAIL alarm indicate detector saturation
    • OVER-RANGE: display reading of “----” and activated low and high alarms indicate that the radiation field being measured has exceeded the counting range of the instrument (or when dead time correction accounts for more than 75% of the displayed reading)

    REMOTE (optional): allows for connection of Ludlum Model 271 or 272 remote units
    CONNECTOR: series “C” (others available)
    ETHERNET (optional): 10 Base-T connection for use with Ludlum’s software
    CALIBRATION CONTROLS: accessible from the front of instrument (protective cover provided)
    HIGH VOLTAGE: user-adjustable from 200 to 2500 volts
    DEAD TIME: user-adjustable to compensate for dead time of the detector and electronics (can be read off the display)
    AUDIO: can vary from approximately 68 dB to 100 dB through operation of the external rotary baffle and the internal voltage connection
    RS-232 OUTPUT: a 2-second dump for computer data logging
    POWER: 9 Vdc wall-mount adapter with four sets of prongs for almost any style wall receptacle
    BATTERY LIFE: typically 48 hours in non-alarm condition; 12 hours in alarm condition
    BATTERY CHARGER: battery is continuously trickle charged when the instrument is connected to line power and turned on
    CONSTRUCTION: aluminum housing with ivory powder-coat finish
    TEMPERATURE RANGE: -15 to 50 °C (5 to 122 °F); may be certified for operation from -40 to 65 °C (-40 to 150 °F)
    SIZE: 18.7 x 24.6 x 6.4 cm (7.4 x 9.7 x 2.5 in.) (H x W x D)
    WEIGHT: 2.1 kg (4.7 lb)
