Professional moisture meter for determining the water content of biomass with optional display of bulk density and bone dry weight (tons/m³). For measuring wood chips, barks, wooden pellets, elephant grass, wood shavings, sawdust and corn cobs.

The BMA for measurements within seconds without prior treatment of samples, with manual saving of results, datalog for 10,000 logs with measuring point report. Also available with the option: BMA-ATRO - Display of bulk density and bone dry weight (tons/m³)

Only the exact determination of water content of biomass allows fair payment for producers, suppliers and end customers. The water content determines the fuel value of biomass. This makes quality control in the manufacturing and supplying of biomass increasingly important. Using a high quality biomass moisture meter you can prevent machine problems and avoid paying the high product price only for water.


  • High measuring range up to 70% water content (dependent on the material)
  • Display of bulk density and ATRO tons/m3 Requires BMA-ATRO option
  • Bulk density compensation by integrated scale
  • Infrared sample temperature measurement
  • Measurement within seconds without prior treatment of samples
  • Automatic temperature compensation
  • 12 liter sample volume
  • Built-in data logger stores up to 10,000 values
  • BMA-USB model adds option USB data output to transfer data to a PC. Includes
  • Other optional accessories are factory calibration certificate, rechargeable batteries and integrated printer
