Turku Benchtop Wood Moisture Meter

The Benchtop Meter That Measured Without Always Marking the Wood

The Turku gave a single benchtop station two ways to read moisture. Its non-penetrating contact probe checked finished surfaces and marking-sensitive stock without leaving pin holes, while its 4-pin needle probe handled standard internal measurement. Both worked by DC electrical resistance, letting an operator choose the right probe for the piece in front of them without switching instruments.

What the Turku Did

• Dual-probe flexibility: Two interchangeable probes — a two-rubber-sensor contact probe and a 4-pin needle probe — covered both non-marking and penetrating measurement from one meter.
• Resistance measurement: Both probes read DC electrical resistance through the wood for a true moisture value.
• Automatic temperature compensation: A built-in thermistor corrected readings for ambient temperature without manual adjustment.
• Benchtop repeatability: A fixed station with selectable SOFT/HARD and wood-group calibration suited shop QC and sample checking.

The Current Pin-Type Meter

The Turku’s heritage of offering both penetrating and non-marking measurement carried forward into Kett’s modern resistance line, now in a portable digital handheld with automatic compensation and digital wood-group classifications.
