Obsolete - See PM450.
Designed to provide immediate, accurate readings of many grains, this unit does not require adjusting or temperature correction. As a fully electronic, built-in microprocessors, the Grainer is the world's simplest handheld multi-grain tester.
Samples can range from 20-180 grams. Twenty-six calibrations are included with the system. Select the product calibration desired, pour the sample into the container and results are shown within five seconds.
This system was replaced by the PM400, then the 410 and currently the PM450.
