PART #:48-3063

INDICATED USE: General purpose survey with alarm capabilities
DETECTOR: 6”(15.2cm) diameter X 1”(2.5cm) thick plastic scintillation detector
SENSITIVITY: Typically 2000 cpm/µR/hr (¹³⁷Cs gamma)
METER DIAL: 0 - 1 µR/hr, BAT TEST (others available )
MULTIPLIERS: X1, X10, X100, X1000
LINEARITY: Reading within ±10% of true value
ALARM: The Model 193 has a dual action alarm.
     1. A fixed alarm point can be set at any point from 10% of full scale to full scale, and is indicated          by a constant audible tone, and the lamp turning on.
     2. A quick deviation alarm that is based on background radiation levels. When the instrument is          turned on, it takes an 8 second measurement of background radiation levels and determines a          deviation alarm setting. If the radiation level exceeds this setting, the alarm audio will beep          every 1/8 second, and the lamp will flash.
AUDIO: Built in unimorph speaker with ON/OFF switch (greater than 60 dB at 2 feet )
CALIBRATION CONTROLS: Accessible from front of instrument (protective cover provided)
RESPONSE: Toggle switch for FAST (4 seconds) or SLOW (22 seconds) from 10% to 90% of final reading
RESET: Pushbutton to zero the meter, and also re-accumulate background data and recalculate the alarm point.
POWER: 2 each “D” cell batteries (housed in sealed compartment that is externally accessible )
BATTERY LIFE: Typically 600 hours with alkaline batteries (battery condition can be checked on meter)
