Ralston Instruments.
Founded in 1969 by Doug Ralston, today Ralston Instruments continues to be a family owned company with a proud history of innovation. Responding to the demand for convenient, accurate ways to calibrate pressure instruments in industries around the globe, Ralston invented the first hand held pneumatic pump in 1969, followed by the development of the first hydraulic hand pump in 1970. That passion for advancing pressure calibration components remains undiminished. In 1993, RI launched the first fully integrated system of Quick-testâ„¢ hoses and adapters. Designed for low volume, high pressure connections to virtually any device being tested, this unique design offers secure, time-saving connections without using a wrench or thread sealant. Ralston's integrated calibration pressure sources are the ultimate solution for performing differential or static pressure calibrations using nitrogen or compressed gas. All Ralston products are made in the USA using superior design and manufacturing techniques. These products include hand pumps, compressed gas control devices, hoses, adapters, and complete calibration kits. When the job requires hand pumps that deliver pressure, hoses and adapters for fast, fail-safe connections, or precision calibration tools, Ralston Instruments provides the most complete pressure calibration solutions whether in the laboratory or in a remote location.
