The oreXpress™ spectrometer delivers the benefits of a full-range NIR spectrometer to geologists in the field. The oreXpress makes mineral identification fast and efficient. In addition to in situ measurement and identification in the field, these geological spectrometers are ideal for core shack logging. In fact, in one application, core logging analysis was cut from six hours to just two hours with an oreXpress spectrometer.
