What is the W.S. Tyler CPA?

In the field of conventional particle analysis, W.S. Tyler, alongside parent company Haver & Boecker, has been a market-leading manufacturer of test sieve shakers for decades. As a result, in the early 90s, our accrued expertise and pioneering spirit provided the ideal platform for exploring the next frontier in particle analysis: integration of powerful computing technology.

Our wide product range, consisting of future-oriented, expandable modular units and systems, guarantees flexible solutions for all applications. Our photo-optical systems have proven their worth with hundreds of minerals in various sectors. Whether in the form of standardized laboratory/online units or customized industrial units, from pharmaceuticals, food, and non-metallic minerals to the plastics and fertilizer industries, W.S. Tyler delivers.
