MT900 Wood Moisture Meter

The High-Moisture Pin-Type Meter for Production Lumber

Drying starts at the green chain, where moisture runs far above what a standard pin meter can read. The MT900 measures by electrical resistance through a penetrating needle probe across a 6 to 80% range, and logs every reading, giving sawmills and kiln operators a documented moisture record from freshly sawn timber through to dry.

Built for Green Timber and Quality Records

• Green and freshly sawn stock: a 6 to 80% range reads high-moisture timber that standard 40%-ceiling pin meters cannot, tracking wood from the green chain through the kiln.
• Documented moisture history: stores 250 readings automatically with data number, date, time, wood group, and moisture value, with optional thermal printer output for hard copy.
• Proven calibration system: selectable hardwood and softwood plus 16 numbered wood-group classifications, the same scheme as the MT730, with ±0.5% precision below 20% moisture.
• Production functions: real-time clock, averaging, block separator for grouping readings, and an upper-limit alarm across the full 10 to 79% range.

Built for the Mill and the Kiln

The MT900 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 MT900 is backed by Kett’s one-year Total Care coverage: parts, labor, and specification compliance, with maintenance agreements available.

Working only with dried lumber and don’t need data logging? The MT730 Wood Moisture Meter offers the same accuracy and 16-group calibration in a simpler meter for the standard 6 to 40% range.

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