Instant Grain and Seed Moisture Meter — Portable, Non-Destructive, Battery-Powered
The PM450 delivers instant, non-destructive moisture measurement for grains, seeds, coffee, nuts, and other small products. With 39 factory calibrations — including 7 dedicated coffee calibrations referenced to ISO 6673 — simply pour your sample and read the result. No grinding, no sample prep, no wait.
39 Pre-Loaded Calibrations: Covers wheat, corn, barley, soybeans, coffee (green, roast, parchment, dry cherry), nuts, seeds, and more — ready to use out of the box.
No Sample Preparation Required: Measures whole samples directly, eliminating the grinding and husking that competitive instruments require.
True Portability with Built-In Compensation: Battery-powered (4 AA), under 3 lbs. A fixed 240 mL sample cup and integrated load cell automatically determine density, while a thermistor in the sample cell reads actual grain temperature — both compensations happen instantly during the pour, with no operator adjustments.
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.
