BM1-KIT - Biomass Moisture Meter with Memory - NO OUTPUT
BM2-KIT - Biomass Moisture Meter with Memory - USB DATA OUTPUT

Humimeter Model BM for testing the moisture content of most types of biomass materials.

Highly accurate moisture meter with automatic bulk density compensation for quick determination of water content of wood chips, barks, wooden pellets, elephant grass, wood shavings and sawdust.

The entire measurement procedure is extremely easy & only takes seconds. Simply turn on the gauge, collect the desired Biomass test sample and pour into storage bin and view the water content (%-moisture) on the large backlit LCD display.

The BM1 and BM2 models both include a built-in datalogger for storage of 10,000 values. The BM2 model ads USB data output for downloading stored data to a PC with included software.


  • Automatic self-calibration re-assures user of reliable measurement results
  • Take measurement in seconds without prior treatment of samples
  • Bulk density compensation by using a precision electronic balance (scale)
  • Large Backlit LCD Display with over-sized numbers makes for easy viewing
  • Supplied with 3-1/2 Gallon (13 liter) plastic bucket for collection of testing sample
  • Rugged stainless steel Storage Bin is integrated with gauge providing an all-in-one measuring system
  • Gauge menus in English, German, French, Italian, Spanish and Russian
  • BM2 includes datalogger for data transfer to PC or Printer documenting moisture measurements, date, batch & temperature
  • Includes Calibration certificate for Precision Scale
  • Includes built-in temp probe for automatic temperature compensation for highest accuracy - under all conditions
  • 2 Year Warranty
  • Optional Wireless Kit offered for BM2 for cable-free transfer of data. (Details below)
