Introduction
This
gamma/neutron survey meter combines Ludlum's Model 2363 survey meter with the
Model 42-41L PRESCILA
neutron detector. The gamma detector is an
energy compensated GM housed internal to the survey meter. The neutron detector
is a proton recoil type which provides excellent measurement results at less
weight than the more traditional REM balls.
Specifications
PART NUMBER: 48-3514
INDICATED USE: Gamma and neutron
radiation survey
DETECTION RANGE:
External: Model 42-41L PRESCILA neutron radiation detector: 0.1 mre/hr - 1 Rem/hr
Internal: Energy-compensated gamma radiation G-M detector: 0.1 mR/hr to 1 R/hr
SENSITIVITY:
Gamma: 1000 cpm/mrem/hr (internal detector)
Neutron: 350 cpm/mrem/hr (with Model 42-41L)
ADJUSTABLE ALARMS: (Indicated by red front panel / LEDs):
Gamma alarm,
Neutron alarm,
Integrated dose alarm
DATA LOGGER: Capable of logging up to 1000 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
LOGGING PUSHBUTTON: Located in the handle; used to store a
reading
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)
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: 2.5”(6.4 cm) arc, 1 mA analog type
METER FACE: 0 - 10 mrem/hr, BAT OK
MULTIPLIERS: X0.1, X1, X10, X100
LINEARITY: Reading within 10% of true value with detector
connected
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 reset
the meter to be reset or to read 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
POWER: 2 each “D” cell batteries (housed in sealed compartment
that is accessible from front of instrument)
BATTERY LIFE: Greater than 150 hours (battery condition can be
checked on meter)
