Payzone Testing Laboratory is a division of Grinding & Sizing Company. The lab was opened in 2001 as part of the company's plan to expand its technical resources. The main focus of the lab was threefold: product development, technical service, and quality assurance.

In addition to the in-house testing, Payzone Testing Laboratory is now available as a "lab-for-hire" to perform independent, third party testing. Testing can be performed according to Payzone procedures or API specifications. A custom-testing regime can be designed to fit the customer's needs as well.

The lab is well-equipped with a wide range of testing equipment. New equipment is frequently being added to our inventory and if you don't see what you are looking for, please call us…we may be able to help.
