Model 375-600 Small Area Monitor

PART NUMBER:48-3458

The Model 375-600 is an area monitor with a 630 in³ shielded plastic scintillation detector .

INDICATED USE:Area monitoring
DETECTOR: 630 in³ shielded plastic scintillation
     DIMENSIONS: 15" (38cm) X 28"(71cm) X 1.5" (3.8cm)
     SHIELDING: 0.125" lead on five sides
SENSITIVITY:30KCPM/µR/hr,¹³⁷Cs
DISPLAY: 4 digits LED display with 0.8" (2cm) digits
DISPLAY UNITS: kcpm
LINEARITY: Reading within ± 10% of true value with detector connected
RESPONSE: Typically 3 seconds from 10% - 90% of final reading
STATUS: (Green Light) instrument functioning properly
HIGH ALARM: Indicated by red 5 inch diameter xenon strobe, red HIGH ALARM light, and fast beep (4 per second) audible tone (can be set at any point from 0.0 - 9999)
LOW ALARM: Indicated by yellow LOW ALARM light and slow beep (1 per second) audible tone (can be set at any point from 0.0 - 9999)
NOTE: Audible alert and alarm indicators can be configured as a single beep if desired
DET FAIL:(red light and audible tone; greater than 68 dB at 2 feet) indicates detector overload, no count from detector, or instrument failure
LOW BAT: (yellow) indicates less than 2 hours of battery power remaining
DEAD TIME: Adjustable to compenstate for dead time of detector and electronics (can be read on display)
OVERLOAD: Senses detector saturation (indicated by display reading "-OL-")
OVERRANGE: Indicates radiation field being measured has exceeded counting range of instrument (indicated by display reading "____"
DATA OUTPUT: 9 pin connector providing 5 decade logarithmic output, RS-232 output, signal ground connection, FAIL and ALARM signals (current sink), and direct connection to battery and ground, relay outputs available
