The “PIK-PP” automated device for measuring porosity and permeability

The device is designed to determine open porosity and gas permeability in baric conditions by the non-stationary filtration method. The pressure drop method is uses in the device to determine permeability with the Klinkenberg correction, slip factor and inertial flow coefficients. The device is supplied with a core holder for manual core loading with a diameter of 30 mm, design of which ensures simplicity and ease of the use. Research is fully automated. Service procedures are also automated, such as: device self-diagnosis and calibration. The management program is universal and designed to achieve maximum productivity and workload. Analyzer maintenance procedures include calibration and leak testing.
