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 )
