The Tramex Hammer-action Pin-type-Electrode HA21SP52B is a heavy-duty moisture testing accessory designed for use with the Tramex CMEX5 and Tramex MEX5 moisture meters. It is made for taking accurate pin-type moisture readings in wood and wood by-products, especially where deeper moisture profiling is required.
This hammer-action probe comes with a cable and pins, allowing technicians to drive the pins into timber to measure moisture below the surface. It is ideal for restoration professionals, flooring inspectors, building surveyors, timber installers and moisture testing specialists who need reliable readings in timber structures, flooring systems and building materials.
What It Is Used For
The Tramex Hammer-action Pin-type-Electrode is used to measure moisture content in timber and wood-based materials where surface readings alone may not provide enough detail.
It is commonly used for:
• Timber flooring inspections
• Subfloor moisture testing
• Water damage restoration drying checks
• Building and home inspections
• Moisture profiling in wood and wood by-products
• Checking joists, framing, skirting, boards and structural timber
• Confirming drying progress after floods, leaks or moisture damage
This probe is especially useful when moisture may be trapped below the surface, and a deeper reading is required.
Compatible With
The Tramex Hammer-action Pin-type-Electrode is compatible with:
• Tramex CMEX5 Concrete Moisture Encounter
• Tramex MEX5 Moisture Encounter
How It Is Used
- Connect the hammer-action electrode to your compatible Tramex meter using the supplied cable.
- Place the probe pins against the timber or wood-based material being tested.
- Use the hammer-action handle to drive the insulated pins into the material.
- Take the moisture reading from your Tramex meter.
- Repeat across different points of the timber or flooring system to identify moisture patterns, wet areas or drying progress.
- The insulated pins allow the reading to be taken at the depth of the pin tips, helping provide a more targeted moisture reading below the surface.

Why Choose the Tramex Hammer-action Electrode?
For professionals working in water damage restoration, timber flooring, building inspections or moisture diagnostics, the HA21SP52B provides a more targeted way to test moisture inside timber materials.
Surface moisture meters are excellent for scanning large areas quickly, but when you need to confirm what is happening beneath the surface, a pin-type probe gives you another level of detail. This makes the hammer-action electrode a valuable accessory for anyone using a Tramex CMEX5 or MEX5 on professional job sites.
It is reliable, easy to use and built for trade use where accurate moisture information matters.
