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. Visit our FAQ page for information about the installation of weighing and measuring devices. If you need further guidance, please call the Weights and Measures office at (605) 773-3697 during normal business hours.
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."
