The Delmhorst BD-2100 is a pin-type moisture meter optimized for measuring moisture content 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.

The BD-2100 moisture meter includes three ranges to increase performance. The wood scale has a range from 6 to 40% and is for flooring and other building materials such as wood studs, floor joists and subfloors. The reference scale reads from 0 to 100 on a relative basis and is for use on non-wood materials, such as concrete, plaster, and insulation. Delmhorst's exclusive calibrated drywall scale measures from 0.2 to 50% and is for use on drywall. The BD-2100 displays reading on a bright clear readout.

The BD-2100 uses integral contact pins mounted on top of meter that provide 5/16" penetration. Other Delmhorst moisture electrodes are accepted by the BD-2100 to increase the versatility of the instrument. A built-in calibration check keeps the instrument accurate.

Application Notes

Here's how some of our customers used this product.

Testing the Moisture of a Subfloor

The Background: Our customer is a homeowner who has discovered some water damage in a house he recently bought and wants a way to see if the damage extends into the subfloor.

The Problem: The customer is unsure of the extent of the water damage and doesn’t want to have to rip out the carpet and hardwood to find out which, of course would cause more damage.

The Solution: We recommended the Delmhorst BD-2100, a pin-type moisture meter optimized for measuring moisture content in a variety of different building materials. The BD-2100 uses interchangeable insulated contact pins including Delmhorst 496 contact pins which are 2” long and can penetrate up to 1-1/8” allowing the homeowner to poke through carpet and hardwood to check the moisture level of the subfloor without having to rip it out first.
