IT IS DESIGNED FOR
Certification of measurement methods and accuracy control of the measurement results of open porosity during petro-physical studies of core and sludge in laboratory conditions.
CAN BE USED FOR
Calibration, verification, measuring instruments for open porosity of rocks, for testing measuring instruments and reference materials for type approval, as well as for various types of metrological control in case metrological characteristics of reference materials meet the established requirements.
SPHERES OF APPLICATION
Scientific research, geology, oil and oil refining industry.
