Quality Control Porometer
The quality control porometer is made from the special design of the capillary flow porosity. This instrument is easy to operate, requires fewer operators, easy to use, less time to experiment, compact structure, and requires minimal maintenance. in a wide variety of industries.
Principles
A fully wetted sample is placed in the sample chamber. The chamber is sealed, and a non-reacting gas is allowed to flow into the chamber to a value of pressure sufficient to overcome the capillary action of the fluid in the pore of the largest diameter, empty the pore, and The unique features of the instrument, especially its ability to generate highly reproducible data quickly, make it highly suitable for quality control and process control operations. The instrument is used in these applications in a wide variety of industries. initiate gas flow through the sample. This is the Bubble Point Pressure. The pressure is further increased in small increments, resulting in flow that is measured until the pores are empty of fluid. Such flow and pressure data are generated using a dry sample. The results are used to compute pore parameters and pore distribution. Pressure required to remove a wetting liquid is related to pore diameter.
D = 4γ cos θ/p
