Neutron Dose Ratemeter - Model 2363 with 42-41L

Spezification

• INDICATED USE: gamma and neutron survey
• DETECTION RANGE:
  • external: Model 42-41L PRESCILA neutron detector:  0.1 mrem/hr-1 Rem/h
  • internal: energy-compensated gamma GM detector:  0.1 mR/hr to 1 R/hr
• SENSITIVITY:
  • gamma: 1000 cpm/mR/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 on request)
  
• AUDIO: built-in unimorph speaker with volume control (greater than 60 dB at 61 cm [2 ft], full volume)
• AUDIO DIVIDE: selectable dual or individual click-per-event for gamma and neutron counts
  
• METER: 6.4 cm (2.5 in.) arc, 1 mA analog type
• METER DIAL: 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 0.64 cm (0.25 in.) 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 200 hours (battery condition can be checked on meter)
• SIZE:16.5 x 8.9 x 21.6 cm (6.5 x 3.5 x 8.5 in.) (H x W x L)
• WEIGHT: 1.6 kg (3.5 lb) including batteries, without detector
