Since 1925, Morehouse has made the Proving Ring. Throughout the world in industry and standards laboratories, the Morehouse Proving Ring is recognized for its lasting reputation of absolute accuracy in the measurement of mechanical forces. Most older proving rings can be updated to digital ones. The analog proving ring is no longer manufactured.
Morehouse is privileged to be a US manufacturer of force calibration products since 1920. Our exceptional service, low uncertainties, and low lead times are part of our success. Having customers who know the value of great measurements and products is the reason we exist.
