Delmhorst BD-2100 Digital Moisture Meter measures moisture levels in wood, concrete, EIFS, and sheetrock

Delmhorst offers you three scales in one amazing meter:

  1. Wood Scale: 6-40% moisture range appropriate for flooring and building materials like wood studs, floor joists, subfloors.
  2. Reference Scale: reads from 0 to 100 on a relative basis.
    Use this one to evaluate non-wood materials like concrete, plaster and insulation.
  3. Gypsum Scale: 0.2% to 50% moisture range; use this on sheetrock.

When you are armed with these three scales, there is virtually no material you cannot evaluate for water penetration.
