The Model 3020 Cement Permeability Tester is used to relative permeability of a set cement sample. The Model 3020 Permeameter is designed using strict adherence to current API/ISO standards specified in API Spec 10B-2 Apendix G and ISO 10426-2. The Model 3020 consists of a stainless-steel pressure vessel, which houses a standard 1-inch diameter cement core sample. A simply designed rubber holder squeezes the sample by tightening the plug down into the pressure vessel. Flow is thereby isolated into the sample without any leakage. Gasses & fluids are passed through the core sample at variable pressures using an exceptionally reliable pressure regulator and accumulator. Pressure and flow rates of the fluid are easily measured and recorded using a pressure gauge and flowmeter, mounted in an easy to view position. Simple operation, top quality parts and durable construction allow long term and low-cost laboratory use.
