Committed To Accuracy From The Beginning

Harry E Zumbrun

History of Morehouse Instrument Company: Filling A Need

In 1920 Morehouse Machine Company started as a local machine shop by William S. Morehouse. The 1920s 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.
