Filling A Need
In 1920 Morehouse Machine Company started as a local machine shop by William S. Morehouse. The 1920's Morehouse team included a very skilled machinist named Harry E Zumbrun. Around this time, the demand for boilers and steam engines was increasing. However, as demand was rapidly expanding, so were catastrophic failures. Many boilers were exploding due to material not being controlled and subpar testing methods. A problem that needed to be solved drove Morehouse to work with the National Bureau of Standards and find a solution. That solution ended up being the Morehouse Proving Ring, which allowed for more accurate calibration of Brinell hardness testers. In addition, the Morehouse Proving Ring standardized the applied force and provided a method to measure material strength more accurately.
Accuracy Is Our Success
Our key to success starts with listening to our customers. When we listen, we find a solution. That solution is often a force-measuring system, adapter, or calibration that meets the customer's need while offering the lowest measurement uncertainties available. Low uncertainties help our customers make more accurate measurements, which saves cost, reduces risk, and increases quality. Our accredited calibration services with primary standards will build confidence in your force measurement process. We create a safer world by helping companies improve their force and torque measurements.

Morehouse Torque Laboratory
From the Morehouse Proving Ring to today's deadweight calibrating machines and load cells, calibration technology has changed over the years, but our dedication to innovation has not. In 2004, Morehouse built a 120,000 lbf deadweight machine with an achieved uncertainty of 0.0016 % of applied force. In 2010 our torque calibration lab was built, which houses a primary torque standard from the National Physical Laboratory (NPL) in England. In 2011, we constructed a Universal Calibrating Machine capable of calibrating force up to 2,250,000 lbf (10MN). Over the last ten years, Morehouse has developed new product designs such as the portable calibrating machine, adapter kits, clevis assemblies, quick-change tension members, torque arms, unique customer-specific products, and better load cells, all with the goal of meeting the needs of the industry and our customers.
