The ORTEC digiDART-LF is a high performance Multichannel Analyzer for use with
NaI(Tl) detectors and modern scintillators such as lanthanum halides. It has been
carefully engineered to perform the most demanding real world, PORTABLE gamma-ray
spectroscopy applications. The digiDART-LF is an advanced, all-digital design,
incorporating three ORTEC-held patents.1
digiDART-LF. . . Tough,Yet Light
Weighing less than 860 grams, the digiDART-LF is an attractive, light-weight instrument; easy to handle, and RUGGED. The case is
molded ABS — the same strong plastic used extensively in automobiles. The outside is coated with a shock-absorbing, easy-grip,
stay-clean coating — just like your other tools. The display and keypad are recessed to protect them if the instrument is dropped. The
connectors are all on one side and recessed for protection. The battery is inside — again for added protection and covered with a
splash-proof door. It can be charged in place, even when the digiDART-LF is operating. The battery is truly integrated into the rugged
digiDART-LF and not simply clipped on the back panel; exposed and easy to break. Changing the battery is simple: just open the door
and replace.
digiDART-LF Display and Keypad
Naturally, the digiDART-LF is entirely computer controllable; but with the built-in display and numeric keypad, it is a DRAMATIC
advance from the current generation of portable MCAs. This high-quality display and easy to use keypad mean it can perform a variety
of tasks without an attached PC.
For in-field applications, a PC is difficult to carry and operate, but without a display you can't see the spectrum or results. The
digiDART-LF's built-in, backlit LCD display panel and keypad provide the confidence you need that your data is good. A clear spectral
display is provided and start/stop control is accomplished simply by a single keypad entry.
The spectral display of the digiDART-LF is patterned after ORTEC's very successful MAESTRO-32 MCA Emulator (ask for the
MAESTRO-32 brochure), in use on thousands of systems worldwide. A 240 x 160 pixel LCD display allows the user to monitor
acquisitions and instrument settings status, with no attached PC. It features a live spectral display with region of interest, peak
information and online activity calculations. ROIs are shown as a bar below the spectrum.
Real Time Activity Calculations. . . NO PC Required!
DigiDART-LF can also perform nuclide ID and activity calculations using internally stored calibration information, at the touch of a
button, and all without the use of an attached PC. Everything is user controlled: the library for analysis, displayed peak labels, unit
labels and calibration parameters. They are all easily downloaded by MAESTRO-32 to the digiDART-LF, but they can be changed
in-field to adapt to your changing needs. Activity is calculated for a list of up to 9 nuclides. The spectral data can be saved and later
re-analyzed in more detail using a more sophisticated PC-based analysis package such as ScintiVision-32.
