The versatility of DSPEC Pro, brought about by the number of unique features and modes of operation, means that it is an ideal solution for a wide variety of applications. Its neat and compact packaging further enhance its applicability. Digital spectrometers are inherently more stable than the analog variety of years gone by, and since the introduction of the original DSPEC, ORTEC has achieved the reputation as the supplier of instruments which represent the benchmark in stability, both relating to temperature and count rate.
