PM450 Instant Grain and Seed Moisture Meter

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.

The Reliable Standard for Instant Grain and Seed Moisture Testing

The PM450 gives you accurate, repeatable moisture readings in seconds — no sample prep, no grinding, no waiting for results. Designed for buyers, sellers, and quality managers who need fast answers in the field or at the point of trade.

Solving Real-World Measurement Challenges

  • Eliminating Sample Preparation Delays: Competitive instruments require grinding or husking before testing. The PM450 measures whole grain and seed samples directly, dramatically reducing test cycles so you can focus on throughput and quality — not sample prep.
  • Reliable Accuracy Without Constant Recalibration: The PM450’s measurement design builds compensation directly into the test process. A fixed 240 mL sample cup combined with an integrated load cell (strain gauge) automatically determines sample density. A thermistor mounted in the sample cell reads actual grain temperature — not ambient. Both corrections happen instantly as the sample is poured, with no operator input and no opportunity for error. Accuracy is ±0.5% (under 20% moisture) compared with standard loss-on-drying reference methods.
  • Broad Application Coverage from One Instrument: 39 factory calibrations cover major grains (wheat, corn, barley, soybeans, oats, rye, sorghum), coffee (green Arabica and Robusta, roast, parchment, dry cherry), nuts, seeds, peppers, and more. Calibrations can be adjusted for local conditions.

Built for Anywhere You Work

At just 1.3 kg (under 3 lbs) and powered by 4 AA batteries, the PM450 goes where you need it — receiving docks, grain elevators, auction floors, truck-top inspections, or field checks. Large buttons, audible confirmation sounds, and a backlit LCD ensure confident operation in any environment. Backed by a one-year manufacturer’s warranty on parts and labor, with maintenance agreements available.
