MT730 Wood Moisture Meter

The Dependable Pin-Type Standard for Field Lumber Testing

When the wood is rough-sawn, stacked, or too uneven for a flat-contact meter, a needle probe still gets the reading. The MT730 measures moisture by electrical resistance through a penetrating probe, giving sawmills, lumber yards, and woodworkers a direct, reliable reading on stock that surface-contact meters cannot sit flat against.

Built for Real Lumber, Not Lab Samples

• Rough and uneven surfaces: the needle probe penetrates to take a reading on rough-sawn boards, stickered stacks, and timber a flat sensor cannot read.
• Wide species coverage: selectable hardwood and softwood calibrations plus 16 numbered wood-group classifications cover general lumber and veneer.
• Accurate in the drying range: ±0.5% below 20% moisture, the band that matters for kiln-dried and finished stock, with readings across a 6 to 40% range.
• No setup overhead: automatic temperature compensation, averaging, and an upper-limit alarm work straight out of the case, with no calibration blocks or software to manage.

Built for the Yard and the Mill

The MT730 runs on six AA batteries, compensates for temperature automatically from 0 to 40°C, and reads to 0.1% resolution on a clear digital display. The needle-probe and conductive-rubber sensor system is field-serviceable, with spare needles included. Every MT730 is backed by Kett’s one-year Total Care coverage: parts, labor, and specification compliance, with maintenance agreements available.

Measuring green timber above 40%, or need printed records? The MT900 Wood Moisture Meter extends the range to 80% and stores 250 date-stamped readings with optional printer output.

Testing finished or veneer-grade wood you cannot mark? The HM540 Wood Moisture Meter reads through surface contact alone, leaving no pin holes.
