Pin and pinless meters answer two different questions
A pin meter measures electrical resistance between two probes pushed into the material, which is accurate at a known depth and leaves two holes. A pinless meter reads a capacitive field over an area, which leaves no marks and averages what it finds — including the metal behind it. Wood readings depend on species, so species compensation is not optional on a timber meter. We compare sensing method, depth, species and material settings, stated ranges, and whether readings are absolute or relative.
Pin type · ± 2.0% stated · 0.10% resolution · 4 wood + 3 building scales
A pin meter publishing both its accuracy and its resolution — ± 2.0% and 0.10% — with seven calibrated scales split between four wood groups and three building materials.
Best for: Timber and firewood, where a pin reading at a known depth is exactly the right measurement.
Pinless · to 40 mm (1.57 in) · round probe for corners and joints · hold, max, min
A pinless masonry meter reading to 40 mm (1.57 in) with a rounded probe shaped for corners, joints and narrow spaces, with hold, max and min functions.
Best for: Masonry surveys where readings have to be taken in corners and along joints.
Wood 5–50% · building materials 1.5–33% · hold · auto-off after 3 minutes
A handheld detector publishing two separate measuring ranges — 5 to 50% for wood and 1.5 to 33% for building materials — with a hold function for readings taken out of sight.
Best for: Quick checks on wood and masonry where the comparison between two spots is the answer.
Pinless ball sensor · to 40 mm (1.57 in) depth · DRY / MID / WET · adjustable alarm · hold, max/min
A pinless meter with a ball sensor reading to a stated 40 mm (1.57 in) depth, showing DRY, MID or WET alongside a value, with an adjustable moisture alarm.
Best for: Surveying a finished wall or floor, where holes are not acceptable and depth matters.
Wall, wood, masonry, screed and concrete · relative 0–100 scale · quick-start guide
A meter reporting a relative 0 to 100 value rather than a moisture percentage, sold with a quick-start guide explaining how to read it.
Best for: Comparing one spot against another during a handover or a survey, with no pretense of an absolute figure.
It depends on the scale and material selected. On a wall, comparing a sound area with a suspect one is far more reliable than a raw figure.
They leave two small holes, invisible on rough timber and a nuisance on a finish. Non-contact avoids the problem.
Density influences the reading. Meters offering a species setting are more accurate.
It depends on what the piece is for and the environment it will live in. Timber that is too wet will move as it dries in place.
It finds a damp area, not its origin. Tracing back to the cause remains diagnostic work.
It measures to a limited depth and is fooled by metal behind the surface. That is a limit of the principle.
Ordinary meters give a surface indication. The standardized measurement of a screed before laying calls for a specific method.
Pins give a local value and leave two holes; pinless sweeps a surface without marking but stays indicative. On a finished floor, pinless is often the only acceptable option.
The value depends on the material and the scale: compare a sound area with a suspect one rather than reading a raw figure. Pins leave two holes, non-contact is fooled by metal behind the surface — and the meter finds the moisture, never its cause.
A column is raised only if four instruments in five publish the value. Below that, it would be measuring the silence of the manuals.
