 GR-110G Hand-held Scintillometer
|
|
The GR-110G is a rugged, lightweight portable scintillometer designed for the field
geologist who requires the accuracy of a digital display, and a large crystal volume for good statistics.
In the high sensitivity mode (0.08 to 3.0 MeV), total counts are obtained at either 1 or 10 second
intervals. For work where ground cover is highly variable, a 0.4 to 3.0 MeV total count HE
(high energy) mode provides more significant geological information since the low energy portion
of the spectrum is subject to the largest variations in Compton scatter absorption. The HE mode can
also handle the high count rates found in drill core and mine face analysis applications.
Special calibration of the GR-110G is not required to maintain high accuracy. All instruments are factory
calibrated, and are highly stable so that relative readings from one instrument to another can be compared,
and readings made at different times can be plotted on the same basis.
The small size and rugged construction of the GR-110G, combined with its accuracy, ease of operation and
advanced features, make it an ideal instrument for the field geologist.
