Celebrating 50 Years of Innovation

Ralston Instruments has been a driving force in the pressure calibration industry since our founder, Doug Ralston, invented the first hand-held pneumatic pump back in 1969. A lot has changed in the industry since then, but we have never strayed from our mission of simplifying complicated calibration processes by developing faster, more user-friendly tools for critical pressure testing, maintenance, and repair operations.

From booming economies to more difficult business climates, we’ve seen a lot in the past 50 years. We’re proud to be able to draw from a half-century of deep-rooted industry knowledge and ingenuity that has allowed us to quickly adapt to economic fluctuations to better serve you.

We are happy to announce the following recent updates to our standard business practices:

  • Reduced minimums so you can order just what you need
  • Shorter lead times so you get your pressure calibration products faster
  • Convenient live chat at our website so you can get your questions answered in real-time

We are here every day from 8:30 AM - 5:00 PM EST, fielding questions and helping you find what you need as quickly as possible.

As we move toward the future, we’ll continue to adjust to the changing business climate as needed - always putting the health and safety of our employees and customers first - in our constant push to develop more convenient and innovative ways to calibrate pressure instruments.

Thank you for putting your trust in Ralston Instruments.
