;Neutron: 350 cpm per mrem/hr (with Model 42-41)
ADJUSTABLE ALARMS (Indicated by front panel - red LEDS):
Gamma alarm
Neutron alarm
Integrated dose alarm

LOGGING PUSHBUTTON: Located in the handle; used to store a reading
DATA LOGGER: Capable of logging up to1000 individual data points with the following identifiers for each point (All data is stored in non- volatile memory, allowing batteries to be removed without loss of data):
gamma and neutron sample counts
;sample number
date/time stamp
current integrated dose
10 character location identifier

RS-232 PORT: Located on the can, this allows the instrument to be connected to a PC for data download, and adjustment of setup parameters.
CONNECTOR: Series “C” (others available on request )
AUDIO: Built in unimorph speaker with volume control (greater than 60 dB at 2 feet, full volume )
AUDIO DIVIDE: Selectable dual or individual click-per-event for gamma and neutron counts

METER DIAL: 0 - 10 mrem/hr, BAT OK, (overload) MULTIPLIERS: X0.1, X1, X10, X100
LINEARITY: Reading within 10% of true value DIGITAL DISPLAY: 6 digit LCD with 0.25" digits
SELECTOR SWITCH: Toggle switch to select gamma+neutron, gamma only, or neutron only
RESET/READ HV: A two position momentary action switch to allow for the meter to be reset or a reading of the current integrated dose on the digital display
RESPONSE: Will vary according to the number of counts present. Typically 2 - 11 seconds from
10% - 90% of final reading
