Scale for Non Read Key Wood Materials Calibration Check Key BD-10 FEATURES Designed to check moisture levels in wood, concrete, EIFS, sheetrock, and other materials Resistance technology recognized around the world as the most accurate method for measuring moisture in building...
BEFORE YOU BEGIN The BD-10 features two scales — one marked “wood” and the other marked “reference”. The wood scale is used to measure moisture content of wood materials over the range of 6% to 40% MC. The reference scale...
26-ES, refer to the correction at the end of the manual. Species – Delmhorst uses Douglas Fir, the USDA standard, as the basis for all wood calibrations. Because the electrical characteristics of different species vary, all species read differently at the same moisture content.
Also look for visible signs of water damage. If you feel a problem exists, use the BD-10 with a #21-E electrode . This electrode includes the #608 insulated pins that penetrate 3-1/4".
Procedure: Using a drill or the available HP-1 hole punch , make 2 (1/4") holes about 3/4" apart at an upward 45˚ angle. Push the #21-E Electrode into the holes through the polystyrene and into the substrate. Press read key and read the moisture content.

Press read key and read the reference scale . If the meter reads in the red or “wet” area, it shows the floor is not satisfactory for covering. If meter reads in the green or “dry” area, the surface is dry. However, subsurface tests should be made to verify if the slab is dry throughout.
Is the slab on grade or suspended? If the slab is on grade, is there an effective vapor barrier under the slab? How thick is the slab? What is the drainage condition of the ground? History of other structures in the area Testing Brick or Concrete for Paint Application Brick, stucco, or concrete surfaces must be dry at the time of application and must remain dry after paint is applied or failure...
Yellow — Borderline Tracing Leaks The BD-10 can help trace leaks in masonry material. Normally, dry plaster, brick, or concrete will contain so little moisture it cannot be detected by the meter. If the meter indicates the presence of moisture you can trace the moisture to its origin.
Detecting Moisture in Insulation: Use the BD-10 with the #21-E Electrode and #608 insulated pins to detect moisture in insulation. These pins penetrate 3- 1/4" and are insulated, except at the tips. Only the uninsulated tips make contact with the material, providing information as to the depth at which moisture is present.
If your meter is not working properly, replace the battery with a new one and check the calibration. If this does not resolve the problem, go to www.delmhorst.com and follow the instruc- tions under the Support tab. If you require further assistance please call 877-DELMHORST...
WARRANTY Delmhorst Instrument Co., referred to hereafter as Delmhorst, guarantees its BD-10 meter for one year from date of purchase and any optional electrodes against defects in material or workmanship for 90 days. If, within the warranty period, you find any defect in material or workmanship return the meter following the instructions in the Service for Your Meter section.
