Specifications:

Internal GM Detector Range: Item 337-443: 0.1 mR/hr to 1 R/hr Item 337-444: 1 mR/hr to 4 R/hr
Display: 4 digit LED display with 0.8 in (2 cm) character height
Display Range: 000.0 to 9999
Display Units: Can be made to display in µR/hr, mR/hr, R/h, µSv/h, mSv/h, Sv/h, cpm, cps and others
Linearity: Reading within ± 10% of true value with detector connected
Response: Typically 3 seconds from 10% to 90% of final reading
Status: (green light) Indicates the instrument is functioning properly
Low Alarm: Indicated by a yellow light and slow beep (1 per sec) audible tone (can be set at any point from 0.0 to 9999)
High Alarm: Indicated by a red light and fast beep (4 per sec) audible tone (can be set at any point from 0.0 to 9999)
Note: Audible indicators can be configured as a single beep if desired.
Detector Fail: (red light and audible tone: > 68 dB at 2 ft) Indicates detector overload, no count from detector, or instrument failure
Low Battery: (yellow) Indicates < 2 hours of battery power remaining
Calibration Controls: Accessible from front of instrument (protective cover provided)
High Voltage: Adjustable from 200 to 2500 V
Threshold: Adjustable from 2 to 100 mV
Dead Time: Adjustable to compensate for dead time of the detector and electronics (can be read on the display)
Overload: Senses detector saturation (indicated by display reading “OL”)
Overrange: Indicates the radiation field being measured has exceeded the counting range of the instrument (indicated by display reading “- - - “)
Data Output: 9 pin connector providing 5 decade log output, RS-232 output, signal ground connection, FAIL and Alarm signals (current sink), and direct connection to battery and ground
Power Requirements: 95 to 135 VAC, 50 to 60 Hz single phase (<100 mA), 6V sealed lead acid rechargeable battery (built-in)
Battery Life: Typically 48 hours in non-alarm condition, 12 hours in alarm condition
Battery Charger: Battery is continuously trickle charged when instrument is connected to line power and turned on Construction: Aluminum housing with white polyurethane enamel paint
Temperature Range: -4° to 122° F (-20° to 50° C). May be certified for operation from -40° to 150° F (-40 to 65° C)

Weight: 6.5 lb
Optional Remote Display
Status: (green light) Indicates the instrument is functioning properly
High Alarm: (red LED) Indicates the radiation level exceeds the high alarm point
Detector Fail: (red LED) Indicates detector overload, no count from detector, or instrument failure
Audio: Unimorph type with ON/OFF switch (> 68 dB at 2 ft)
Power Requirements: Provided by PRIMALERT (20 ft cable included)
Construction: Aluminum housing with ivory polyurethane enamel paint
Temperature Range: -4° to 122° F (-20° to 50° C)
