Weiss Technik Test Laboratories

About Us

Our testing facilities consist of two locations with one being on the main campus in Sharonville and a second laboratory in Sterling Heights, MI. Originally named ESSC, our test laboratories have grown in capacity and services steadily by providing world class testing services to many automotive suppliers in the Detroit area. By leveraging our experience with environmental test chambers from the CSZ brand of test chambers, we were able to support industries such as aviation, defense, pharmaceutical, medical device, package testing and much more.

As part of the Weiss Technik North America, Inc. family, the largest domestic supplier of environmental test chambers, and with connections to the longest tenured environmental test chamber provider in the world, our ability to provide world-class environmental testing solutions is unparalleled.

Our Environmental Test Chambers

We have proudly supplied world class temperature management solutions to our customers since we first opened our doors in 1940. Our primary focus at this time was manufacturing industrial freezers. The CSZ brand quickly became synonymous with long-lasting, reliable, and high quality products.

From our humble beginnings, we have grown from a supplier of industrial freezers to become a leading manufacturer of standard and custom environmental test chambers. These test chambers now include a wide variety of thermal, vibration, humidity, altitude solutions, and much more. Over time it became clear that the addition of a testing laboratory would not only provide more opportunities for growth but would allow us to provide a more complete portfolio of environmental testing solutions to our customers.

Throughout our journey to become one of the premier worldwide suppliers of environmental testing solutions we have held true to the philosophy that the customer comes first. This dedication to customer service has allowed us to work with leading manufacturers in over 22 industries including aviation, automotive, aerospace, defense, medical, energy, to name a few.

Located in Sharonville, Ohio, our campus is comprised of two buildings with over 150,000 square feet of manufacturing space. Each building has been tailored to provide flexibility, comfort, and safety for our employees while providing room for continued growth and innovation.
