Weighing & Measuring Device Installation

South Dakota maintains a registry of service agents who are responsible for the installation, repair and maintenance of weighing and measuring devices in the State. Questions on the installation of weighing and measuring devices can be called into the office for further guidance.


Legal for Trade Devices

Legal for Trade devices are required for commercial applications where product is sold by weight or measure. This means that a given device has received a Certificate of Conformance from a NTEP (National Type Evaluation Program) Approved laboratory and complies with the National Institute of Standards and Technology Handbook 44.

South Dakota statute says that Legal for Trade devices must be installed and placed in service by a service agency registered in the State of South Dakota.


Heavy Scale Installation

The installation of heavy scales including vehicle, livestock or hopper scales can be costly. It’s imperative that the scale is NTEP- approved and properly installed to ensure that it’s capable of being certified and sealed by a State Inspector. If a scale is not Legal for Trade or is improperly installed and placed in service, the State Inspector may reject or condemn the scale.

Regardless of the weighing or measuring device type, at installation (or following device repair), ARSD 20:01:06:09 requires that all equipment "...be set as close to zero tolerance as possible."
