21-E
Model No. :
Brand : Delmhorst
The is a specialized Behind-The-Wall Probe designed for non-destructive inspection of moisture content in materials concealed by finished surfaces. Utilizing insulated pins, it allows the user to penetrate materials like drywall or stucco to take accurate readings in wall cavities and insulation, isolating the measurement at the pin tips.
- Specialized probe for behind-the-wall moisture testing.
- Insulated pins measure moisture at 3 ¼” depth.
- Ideal for water damage restoration and roof materials.
− Features
- Deep Penetration Capability: Comes standard with insulated pins, providing up to 3 ¼”() of penetration, ensuring the electrode reaches insulation or framing within standard wall assemblies.
- Insulated Pin Accuracy: The insulation prevents electrical contact with shallow or surface moisture, guaranteeing that the resistance reading is taken only at the deepest point of contact ( ), which is critical for identifying concealed leaks.
- Versatile Construction Material Use: Excellent for restoration and inspection work, allowing for the moisture testing of insulation behind drywall and stucco, as well as the sub-surfaces of roofing materials.
- Optional Extended Lengths: Available in an alternative configuration () which accepts -inch pins for greater depth, and as the model which features a tapped handle to attach an extension pole.

FAQs
How does the measure moisture behind a wall?
It uses , -insulated to penetrate the wall surface, with the meter taking a reading only at the uninsulated tips deep inside the wall cavity.
Why are the on this probe insulated?
The insulation ensures the meter’s reading is isolated to the deepest point, preventing misleading measurements from surface moisture or shallow material layers.
What is the standard pin penetration depth for the ?
The standard pins provide a maximum penetration depth of 3 ¼inches for testing.
Are there options for deeper wall penetration?
Yes, a variant () is available that can accommodate up to for deeper exploratory work.
Which meters can use the probe?
The electrode is designed for compatibility with all pin-type resistance meters that have an external electrode jack.
