Material Testing Center


Thayer Scale’s state-of-the-art material test center enables our customers to evaluate trial runs on volumetric and gravimetric feeding equipment, and to benefit from our engineering team’s deep technical expertise. At the test center, a dedicated technician helps customers replicate industrial processing conditions to assess and resolve any material handling difficulties. Our test center is particularly useful for clients who are (1) new to volumetric or gravimetric feeders, (2) verifying feeder performance and/or accuracy, (3) using new materials, or (4) consistently experiencing material feeding problems.
