About

Dr. Krishna Gupta founded Porous Materials, Inc. in 1978 for the development and manufacturing of sophisticated and fully automated porosimeters for characterization of pore volume of porous materials.

Since then the company has grown considerably. PMI currently holds many US and international patents on novel technology for characterization of pore structure, has six product lines (Porometers, Permeameters, Intrusion Porosimeters, Extrusion Porosimeters, BET/Sorptometers, and Pycnometers), manufactures over thirty different instruments and many custom instruments, houses a contract testing laboratory with an international reputation, and has a consulting group that takes pride in finding solutions to the porosity problems of companies.

From the beginning, PMI's primary endeavor has been to remain in the forefront of modern technology, explore innovative ideas, refine existing technologies, and develop novel products to meet the growing demands of modern technology through distributors around the world. The same principles continue to drive us today. PMI has the reputation for being the most advanced and user-friendly company in the field.
