The BL E is a triple measuring instrument for wood moisture, structural moisture and temperature. 
The device allows accurate measurements of wood, building and insulation materials according to the electrical resistance measuring method.The wood moisture measuring circuit enables the measurement of lumber (up to 180 mm thick), chipboard and hardwood flooring. The Hydromette is equipped with material specific settings for an automatic correction of readings for 23 building materials and insulants, for instance, screed, mortar, renders, concrete, brick and several insulants. The connection of an B 55 BL active electrode enables the non-destructive moisture measurement and indication-in ceilings, walls, floors, and other building materials.

• Wood moisture:
  5,5 - 58% (dry mass)

  Structural moisture:

  resistance-based measurements:
  0,1 - 42,2 wt.-% or 0,2 - 9,9 CM-% depending on the material to be measured

  0 - 200 digits scanning range

  Temperature:
  depending on the Pt100 temperature sensor between -50 to +350 °C

  Infrared measuring range:
  -40 to +380 °C with IR 40 BL

• Handy pocket-sized high-speed measure meter for fast single and series measurements including a high-quality measuring amplifier
• Direct indication of wood and structural moisture in wt.-% or CM-% for resistance-based measurements via a 3-line LCD, resolution: 0.1 % or 0.1° C;
• When connecting a B 55 BL the scan mode returns values between 1-200 digits
• 2-level wood species correction (characteristic curve groups 2 and 3) for automatic measurement value correction  
• Rapid measurement of hardened building materials by the high-frequency capacitive measurement method using a B 55 BL active electrode
