ASP-2E/NRD Portable Neutron REM Survey Meter

  • Neutron Dose Equivalent Rate
  • BF3 Tube Allows High Gamma Rejection
  • User-Friendly Analog/Digital Display
  • Ratemeter, Integrate & Scaler Operating modes
  • Quick Computer Assisted Calibration
  • Alarm Annunciation
  • Built-In Speaker

Portable, convenient, and easy to use, the ASP-2e/NRD survey meter employs a highly responsive neutron detector, measuring dose equivalent rates over the energy range from 0.0025 eV to about 10 MeV. The detector's BF3 tube provides excellent gamma ray rejection. The probe can be easily detached from the meter to
provide better coverage in ergonomically difficult positions. A user-friendly LCD complements the analog meter.

The ASP-2e/NRD is a portable, battery operated counter designed for the measurement of dose equivalent rate from neutrons (Rem). The detector employed is a 22.9 cm (9”) diameter, cadmium loaded polyethylene sphere with a BF3 tube in the center. This detector has been shown to have a response which closely follows theoretical dose equivalent from neutrons over the energy range from 0.0025 eV (thermal) to about 10 MeV. The BF3 tube also provides excellent gamma rejection.

The accompanying instrument is the model ASP-2e. This design combines the best features from conventional analog counters and marries them with state-of-the-art digital techno-logies to present the user with a very capable and user-friendly
instrument.

A dual analog/digital display facilitates the measurement process by presenting informative data in an optimum format. While the traditional analog meter scale presents relative scale and movement of the counts received,

the digital display forwards exact count rate readout together with the units employed, the counting
interval or elapsed time (depending upon the operating mode selected) along with other key operational parameters such as response time selected, alarm setpoints, high voltage, battery level, etc.

Microprocessor-based, the ASP-2e/NRD corrects for coincidence loss so that the upper limit range of the detector is increased by a factor of ten or more. When the useful range is exceeded, an over-range alarm is given. The instrument has a built-in
speaker, serial port for PC setup and calibration, and an easy access external battery compartment to facilitate battery replacement.
