The “PIK-GGC-4” group gravimetric capillarymeter

The PIK-GGC-4 installation is a modified version of the PIK-GGK-6 group capillarymeter and designed to determine core samples capillary properties and residual water saturation using a semipermeable membrane at atmospheric conditions in accordance with OST 39-204-86. Capillary properties are determined in the excess gas pressure range from 0.0007 to 1.38 MPa in the entire range of sample permeability and water saturation of samples pore space from 100% to residual values.

Benefits/Capabilities:

Desaturation camera is made of stainless steel, providing its resistance to aggressive environments and durability
Up to 4 desaturation camera can be connected to the capillarymeter control panel through 4 pressure control units
Each unit has its own pressure control range: from 0 to 0.1 MPa; from 0 to 0.3 MPa; from 0 to 0.5 MPa and from 0 to 1.5 MPa, with an accuracy of not more than 0.25%
Pressure maintenance is adjusted automatically
