We offer dead weight testers built for stability and repeatability. They calibrate, test and repair the devices used during pressure measurement and control. Our selection features industrial testers designed for high performance and those that serve as primary standards in the field or lab. We offer a deadweight tester inventory that includes pneumatic, hydraulic, high pressure and dual range models. Units are available with single piston/cylinder, dual piston/cylinder or floating ball assemblies. We provide testers operated by oil, gas or water that meet demanding calibration requirements. Ametek M&G, Fluke Calibration, and Ashcroft are some of our standout brands available today.
