The ETI Heavy Duty Hammer Probe is a specialist moisture probe for UK property maintenance technicians and building services engineers who need reliable moisture readings in wood, timber and similar materials. Designed for use with ETI moisture meters with a BNC connector, it helps pinpoint damp and moisture ingress during surveys, remedial work and inspection routines.
With insulated shank pins, the probe measures at the pin tip, enabling more accurate readings and allowing checks at varying depths, ideal when surface readings aren’t enough. Supplied with a 1 metre PVC lead and BNC connector, it’s a practical add-on for technicians working across joinery, flooring and building fabric.
Why use a hammer probe instead of standard pins?
A hammer probe provides stronger penetration and more consistent contact when testing dense or hardened timber, where standard pin probes may struggle to reach the required depth. The insulated shank pins ensure moisture is measured only at the pin tip, helping technicians assess moisture levels deeper within the material rather than being influenced by surface conditions. This makes hammer probes particularly useful for structural timber, flooring, joists and concealed areas where accurate depth readings are essential for reliable damp assessment.
