Moisture Meter for Waste Paper

AP 500-M3 moisture meter is a digital one-hand-held measuring device for the quick and mobile moisture determination without sample-taking for the detection of moisture accumulation in stacks, waste paper bales and loose depots of waste paper. The moisture meter determines the absolute humidity in waste paper by simple pressing. This moisture content allows a water-precise billing of a waste paper delivery. At the same time a complaint of too wet bales prevents not only costs but also unpleasant consequences such as rot or heat.


  • Lightweight, robust and mobile: attaching – reading – storing
  • Quick, non-destructive measuring of the absolute humidity of waste paper up to depth of 500 mm
  • Pre-programmed calibrated for different materials and bale densities
  • Digital displaying in “%” water content (weight percentage)
  • Temperature measuring value for each moisture measuring value
  • Temperature compensation of the moisture value
  • Data log function: automatic redcording and storing with date and time as well as entering of supplier data and charge number possible
  • Data output of the last measuring series or all measuring values by the USB-interface at the pc or printer
  • Analysis of measuring values by an analysis software in EXCEL, database and statistic function
