HM540 Wood Moisture Meter – Instant, Handheld, Portable – Non-Destructive

The Professional Standard for Non-Destructive Wood Moisture Measurement

Most pinless meters stop reading where the real moisture problems begin. The HM540 measures from 2 to 150% across more than 400 species, giving sawmills, kiln operators, and hardwood importers an accurate moisture reading on green, wet, and dense timber, all without driving a single pin into the wood.

Built to Read What Other Meters Cannot

• Green and wet timber: a 2 to 150% range reads freshly sawn and kiln-charge timber well beyond the 30-something percent ceiling typical of contractor-grade pinless meters.
• Dense and tropical hardwoods: a specific gravity setting from 0.10 to 1.25 covers more than 400 species, including dense exotics that fall outside narrower correction bands.
• Finished and veneer-grade surfaces: high-frequency capacitance through two metal sensors measures inside the wood without pin marks, protecting product you intend to sell.
• Quality-control records: 999-point internal memory plus USB logging through the optional HDL-02 software turns spot checks into a documented moisture history.

Built for the Mill and the Kiln

The HM540 reads in roughly a second through simple surface contact, compensates for temperature automatically from 10 to 40°C (and manually from −10 to 70°C), and adjusts for material thickness from 10 to 40 mm. It carries JHWTC authorization as a moisture meter for conifer timber, a level of independent recognition that contractor-grade meters do not hold. Every HM540 is backed by Kett’s one-year Total Care coverage: parts, labor, and specification compliance, with maintenance agreements available.

Need to measure where you cannot reach a flat surface? The MT730 Wood Moisture Meter uses a penetrating needle probe to read rough, uneven, and stacked lumber the capacitance method cannot sit flat against.

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