About Our Company...

In 1947 we offered commercial equipment for pressure up to 200,000 psi. In fact, we were the sole suppliers of equipment above 3 Kilobar (45,000 psi) in the United States.

In the intervening years, Harwood developed the "Controlled Clearance" principle upon which primary standards of pressure above the manometer level, to as high as 30 kbar, are used throughout the world. We are currently making primary force standards in a new apparatus using a variant of this same principle.

For fifty years we have made equipment for producing pure isostatic pressures to 30 Kilobar (430,000 psi), at room and elevated temperatures. We also make presses up to 10,000 tons of quasihydrostatic pressures so necessary in the manufacture of diamonds and fundamental studies in pure physics, geophysics, and geochemistry.

Our market is relatively small and does not justify extensive "agency" type of marketing since so much of our effort is to customer specification requiring direct and personal contact with our clients.

Any group seriously considering high pressure activity can find generous recognition of our efforts by authors in this field as well as many of our own published articles.

There is a tabulation of a few Harwood innovations that have solved difficult problems. Do you have similar ones that we might help you with?
