BD-2100



Overview

The best-selling BD-2100 is great for measuring moisture in a variety of different building materials, including wood, concrete, drywall, EIFS, roofing, insulation, and flooring. The BD-2100 has a digital display, an adjustable alarm, and Delmhorst’s exclusive calibrated drywall scale.

Features:

  • Bright, clear digital display.
  • Three scales:
    • Wood Scale - 6% - 40% moisture range. Use for flooring and building material, such as wood studs, floor joists, subfloors.
    • Reference Scale - Reads from 0 - 100 on a relative basis. Use on non-wood materials, such as concrete, plaster, and insulation.
    • Gypsum Scale - 0.2%-50% moisture range. Use on drywall.
  • Averages up to 100 accumulated readings.
  • Built-in calibration check.
  • Audible, adjustable alarm alerts you when your pre-selected MC has been reached.
  • Integral contact pins mounted on top of meter provide 5/16” penetration.
  • Built-in connector accepts any Delmhorst electrode.
  • Size: 8” x 3” x 1 5/8”.
  • Weight: 10 oz.
  • Rugged construction ensures years of reliable use.
  • Sturdy plastic carrying case.
  • 9V battery.
  • 1-year warranty.

Electrodes

Delmhorst offers a wide assortment of electrodes known throughout the industry for their durability. All Delmhorst electrodes fit any Delmhorst moisture meter. Below are electrodes that are typically used for this model:

2-E

Fitted with the same 5/16" penetration pins that are mounted on our pin type meters. This electrode is great for a variety of different applications:

  • Home inspector: Use on wood joists and drywall.
  • Paper producer: Use on curved surfaces such as cardboard and paper tubes.
  • Woodworker: Use on timber, poles, and veneer.

2-E is also available as the 2- ET with a tapped handle for hard to reach areas. Can also be fitted with A-103 uninsulated pins with 1 3/32” length and 11/16” penetration.

26-ES

The 496 contact pins that come with the 26-ES penetrate 1 1/8” and have insulated shanks so that only the tips are exposed. The pins make contact only at their uncoated tips and provide much more accurate readings of moisture content at various levels of penetration. This feature is useful for a variety of different applications:

  • Flooring installers: Penetrate through flooring to plywood sub-floor, or concrete.
  • Dry kiln operators: Identify moisture gradients which helps to identify the drying pattern.
  • Furniture manufacturers and craftsmen: Easily check high density hardwood that short pins are unable to penetrate.

Also available as the 26-ED, which includes gauge to measure pin penetration depth.

21-E

The 608 pins that come with the 21-E are insulated, except at the tips, and can reach a maximum penetration of 3-1/4".

Great for use on roofs, insulation, or EIFS.

21-E is also available as the 21-E/001 with 6" penetration, or as the 21-ET with a tapped handle for hard to reach areas.

19-E/STC

Features two 5'' long blades, bent to a 35° angle, and coated in Teflon except for the tips. Great for checking behind trim and baseboard molding.

Accessories
 
2497/A-100
Uninsulated pin and retainer with 5/16" penetration. Standard on all meters with built-in pins and the 2-E and 4-E electrodes. Used on wood up to 6/4 (1 ½”), concrete and gypsum.
305RET-0021

Retainer used to hold contact pins in place. Used with #608 and #608/001. Available in packs of 4 as 305RET-0021/4.

496

496 contact pins are insulated except at the tips, and measure 2" overall with 1 1/8" penetration. Standard on the 26-ES, and can be used to check wood up to 5" thick.

608

The 608 insulated contact pins measure 4" overall, and penetrate 3 1/4". Standard on 21-E and 18-ES electrodes, and can be used on roofing, insulation, timber, poles, and EIFS. Also available in 7” length with 6” penetration as 608/001.

632

Retainer used to hold contact pins in place. Used with #496, #1849, and #A-111 pins. Available in packs of 4 as 632/4.

A-111

Another alternative to the 496, the A-111 is an uninsulated contact pin measures 1 7/16” and has 1/2" penetration. The A-111 is compatible with both the 26-ES and the 22-E, and its tapered point makes it easier to penetrate into hard surfaces. Can be used on wood up to 2" thick.

HP-1
Makes pilot holes in stucco to reduce pin damage.
MCS-1

Moisture content standards are great for verifying that your Delmhorst moisture meter is in calibration. The MCS-1 can be used on any meter with a wood scale. With two electrical resistance values (12% and 22%) to test your meter against, you can be sure that your readings will stand up to the strictest standards of accuracy. The MCS-1 is also available with a letter of certification traceable to NIST.
