Edward Ashcroft was a pioneer in pressure measurement instrumentation. He started the company in 1852 after acquiring the U.S. patent rights for the Bourdon tube from its inventor Eugène Bourdon. This milestone led to the widespread adoption of the “Ashcroft Gauge” in American industry and laid the foundation for the company’s continuous growth and innovation.
The acquisition by Nagano Keiki Co. Ltd. in 2006 expanded Ashcroft’s global capabilities even further and strengthened its technical capabilities. Today, with more than 170 years of experience, the company has worldwide recognition as a trusted leader in industrial measurement and control instrumentation, delivering engineering expertise, product reliability and long-term commitment to customer success.
With over 1,000 employees worldwide, and a complete portfolio of pressure and temperature instruments, Ashcroft products are relied on by the world’s leading companies for their mission-critical applications.
“At Ashcroft we measure more than pressure and temperature. We measure ourselves by the trust given to us by our customers. Our focus is to deliver safe, reliable solutions backed by real support so our customers can operate with confidence every day,” said Adam Freyler, Ashcroft President.
