USDA GIPSA/FGIS Certified as UGMA Compatible

The USDA developed the Unified Grain Moisture Algorithm (UGMA) to improve accuracy and repeatability of moisture in whole grains and oilseeds. To properly implement the UGMA, the instrument must also use a higher radio frequency (149MHz), test for density, and accurately measure temperature. The new meters are twice as accurate on many grains and much more capable of taking into account grain temperature variation. The Aquamatic 5200-A is approved for use for official grain trade in the United States. Here is a list of the grains, oilseeds, and pulses covered.

NTEP Approved Grain Moisture Meter

NTEP approval means that the Aquamatic 5200 and was put through a rigorous set of tests and found to meet or exceed the National Institute of Standards and Technologies (NIST) Handbook 44 requirements for testing devices. The purpose of NTEP is to provide a framework to systematically test devices that will be used “for selling, purchasing, exchanging, custody transfer, or establishing the cost for services or hire on the basis of a measurement” according the NTEP website.

The Aquamatic 5200 Grain Moisture meter is officially approved in Germany and France. In Germany, the AM 5200 Grain Moisture meter was approved by PTB for official Moisture payment analysis in December 2014. In France this approval was finalized by LNE in May 2015.

The official agencies in Germany (PTB) and France (LNE), have through thorough testing concluded that the AM 5200 meets the requirements on accuracy, stability and integrity, resulting in the approval for determination of moisture in various grain types in commercial grain trading.
