Celebrating 100 Years of Morehouse and 100 Morehouse Blog Posts

100 Years of Morehouse and 100 Blog Posts on mhforce.com

The 100th blog post, what to do? 100 years in business, 100 blog posts, several papers, and technical articles along the way. Communication has changed from a switchboard phone to a handheld personal computer that can receive this message. From the proving ring to today's deadweight calibrating machines, calibration technology has also changed over the years. Lots of history, lots of learning, lots of education, lots of false starts, some abandoned, some quite successful, others not so much, and so much gratitude to all.

Many of you have been with Morehouse for years, maybe decades, and all I can say is that you have enriched our lives. From past employees, owners, and customers, you all have shaped who we are today, and for that, I thank you. Thank you for your hard work, your mistakes that created headaches, those headaches that helped us learn and become better, your trust, and your help in making us always want to be better.

So, for our 100th post, I thank you all. May we continue this journey together, and as for the ups and downs; you all have played a part in this journey, and we look forward to continuing it. Below is a list of some of my favorite blog posts followed by pictures of our history over the last 100 years.

100 Years of Morehouse and Some Interesting Pictures

Morehouse Springiness Tester circa 1920's I believe about a dozen were sold.

1927 Morehouse Brick Tester... What could have been our foray into the testing industry? There wasn't much of a market there 🙂

Instead, circa 1930's we decided to make and refine the greatest force instrument to calibrate testing machines.

And by the 1950s, what would be used to calibrate the Proving Rings, Morehouse Deadweight Machines, of course?

The 1960s brought the Unipour, which sold maybe 1 unit. The rumor was that the person who tested it was too short, and it failed.

The 1960s brought the Morehouse semi-digital balancing instrument proving ring.

A Wheel Load Weigher Machine used to Calibrate Truck Scales circa the 1970s

Enter the digital revolution of the 1980s and Morehouse Digital Ring Force Gauges.

In 2004, Morehouse built a 120,000 lbf deadweight machine with an achieved uncertainty of 0.0016 % of applied force.

2017 A Morehouse Portable Calibrating Machine. This product has been part of our continuing designs, where we are now developing two to four new products per year that meet customer needs.

Here at Morehouse, we believe in changing how people think about Force and Torque calibration. We challenge the "just calibrate it" mentality by educating our customers on what matters, what causes significant errors, and focus on reducing them. Morehouse makes simple-to-use calibration products. We have certainly had some misses throughout the years; however, we build fantastic force equipment that is plumb, level, square, rigid, and provide unparalleled calibration service with less than two-week lead times.
