Installations are often a practically invisible part of a building. Miles of cables, piping, tubes and wires are concealed behind the ceilings, floors, walls and foundations. The facilities themselves are tucked behind voids or form unsightly blemishes on rooftops.


Ashcroft is the leading source of temperature and pressure instrument solutions for critical Process and Industrial/OEM (original equipment manufacturer) applications across the globe. Our extensive industry experience and customer-driven approach allow us to provide solutions that fully accommodate the needs of your critical processes and applications ensuring accurate and safe operations.

A Legacy of Protection for What Matters Most

With over 165 years of innovation woven into its history, Ashcroft is widely recognized as a global leader in pressure and temperature measurement instrumentation.

Edward Ashcroft founded the company in 1852 with a mission to protect steam-powered industry workers with more sophisticated, reliable instruments. Today, Ashcroft instruments—gauges, thermometers, switches, transducers, transmitters, instrument isolators, diaphragm seals, and control and calibration equipment—are considered a benchmark for temperature and pressure measurement.

Throughout Ashcroft’s history, numerous expansion efforts have led to a significant increase in our global reach as a trusted source for pressure, temperature, and test instruments.  Most recent examples include:

  • In 2006, we were purchased by our parent company, Nagano Keiki Co. Ltd. of Japan.
  • In 2007, we opened a manufacturing facility in Suzhou, China.
  • In 2011, Steven A. Culmone named CEO and President of Ashcroft.
  • In 2015, we opened a new sales office in Turkey.
  • In 2018, we opened a new sales office in Dubai, UAE.
  • In 2019, we acquired Rüeger Holdings SA (Rüeger) and STIKO Meetapparatenfabriek B.V. (Stiko).
