Kett has developed a variety of highly successful moisture meters for portable use. The Instant Moisture Meter Kett PM-650 is the latest in our product line and is indispensable for the grain, seed, and coffee industries.

The Instant Moisture Meter Kett PM-650, version 6501 is a general purpose instrument for worldwide use. It will measure a wide variety of applications including wheat, corn, sunflowers, hazelnuts, coffee, tea. etc.

Up to 150 applications may be installed.


  • Wide Measurement Range:  The Instant Moisture Meter Kett PM-650 can measure the moisture content in grain and seed samples between 1-40% depending on the grain and the Instant Moisture Meter Kett PM-650 version.
  • Automatic density and temperature correction: The capacitance principle is affected by both density and temperature. The PM-650 includes an integrated scale and thermistor to automatically compensate for variation in both, ensuring accurate moisture measurement each time.
  • Sample density (g/l) is provided: The Instant Moisture Meter Kett PM-650 automatically calculates the sample density (sample weight/volume).
  • Printer and data output options: The Instant Moisture Meter Kett PM-650 can be connected to an optional thermal printer or PC.
  • Stable load cell: Improvements in the load cell provide even better weight measurement stability when compared with our earlier models.
  • Versatile operation: Lightweight, easy to hold, large buttons, audible and display icons make the PM-650 an instrument anyone can use, in almost any environment.
