The Henry G. Dietz Co., Inc. was established in 1947, engineering and designing products with low pressure / vacuum technology. Its products are used for detecting air flow, dirty air filters, pressure / vacuum, and for measuring and monitoring these functions in clean rooms etc.. It also specializes in manufacturing high quality products for unusually harsh environments.

To help engineers interested in low pressure / vacuum technology, we offer free software as well as engineering booklets to aid in the proper application of Dietz products.

Over the years The Henry G. Dietz Co., Inc. expanded its product lines to meet a wide variety of special needs, even developing a way to manufacture silicone rubber diaphragms only 0.002" thick..
Our Model 85S can be used as a forced entry sensor that detects the pressure drop when a window, door, or other opening is made in a pressurized building.
The Henry G. Dietz Co., Inc.also has a marine division that manufactures navigation products and Powerboat Handling Trainers. At one time it manufactured a 1910 runabout automobile, and is looking to sell parts and tooling for this product at a give-away price for we do not have room any longer for its assembly line..
