PM410 Instant Grain and Seed Moisture Meter

Whole-Sample Grain and Seed Moisture with Built-In Weighing

The PM410 measures moisture across a 240 mL sample of grain or seed and returns an instant, non-destructive reading. It compensates automatically for both the actual density of the sample and its temperature, so you get a dependable figure without sample preparation or a separate scale.

Built to Handle Real Receiving-Line Conditions

• Automatic density and temperature compensation: the fixed 240 mL sample volume and integrated balance measure each sample’s actual density, and a built-in sensor corrects for temperature, keeping readings consistent across samples and conditions.
• One meter for the main crops: 12 factory calibrations cover wheat, barley, corn, soybeans, canola, rye, oats, sorghum, sunflower, paddy, and rice.
• Average out the scatter: store up to nine readings and average them for a stable figure across a lot.
• Tune to your reference: a per-grain bias adjustment aligns readings to your own standard for local conditions.

Built for the Field and the Elevator

At roughly one kilogram and powered by four AA batteries, the PM410 goes from the receiving pit to the farm without an external scale or sample preparation. Pour the sample, read the moisture, and move on.

Service and Replacement

The PM410 is no longer manufactured. The upgraded instrument is our PM450 Instant Grain and Seed Moisture Meter, which expands coverage to 39 factory calibrations spanning grains, coffee, nuts, and seeds. Kett continues to provide parts, service, and support for PM410 units already in the field.
