Welcome to Hewitt Industries of Los Angeles
In 1952 while in the trucking business, John T. Hewitt designed and developed the first pyrometer (E.G.T) used for trucks. In 1955 Hewitt Industries was formed and began developing the market for users and O.E.M.'s around the world. Hewitt maintains this leadership through the highest quality in design and product reliability.

Continuing improvements in manufacturing and worldwide patents for product design has allowed Hewitt Industries to supply its customers, users and O.E.M.'s, with attractive superior products at lower prices.

In March 2008 Hewitt Industries was ISO certified to ISO 9001:2008. All products are manufactured in the U.S.A.

Hewitt Industries prides itself on providing high-class products at an affordable price. If there is anything that you may have questions about or may not be able to find on our website please contact us and we will assist you further.
