Merrick History

Herbert Merrick

In 1908, an engineer named Herbert Merrick developed the first dynamic weighing machine based on the idea of mechanically calculating gravimetric flow rates from belt speed and weight. Little did he realize that he would fundamentally change the way the world measured material flow.

Herbert Merrick began the Merrick Scale Manufacturing Company in Passaic, NJ to produce his new invention. The company has been in continuous operation ever since. Although many new products would change the weighing industry over the next hundred years, MERRICK has remained a driving force in the advancement of dynamic weighing and material handling technology with a full line of solutions.

Tannehill Purchase

In 1991, the company was purchased by Tannehill International Industries, and the engineering and design functions were integrated into the existing Lynn Haven, Florida facility.

MERRICK’s 50,000 square foot facility houses customer support, engineering & manufacturing. The MERRICK facility has full, in-house capability including complete metalworking, ASME Boiler and Pressure Vessel Code and National Board Stamps, certified welders, and USDA listing.


In 1994, MERRICK opened a new service to the industry as MERRICK Environmental Technologies, a full service supplier of air pollution control and dust collection equipment.
