Pin-Type Wood Moisture Meter — 80% Range, 250-Reading Memory, Green-Timber Ready
The MT900 extends pin-type measurement to 80% moisture content and stores 250 date-stamped readings, built for sawmills and kiln operators tracking green and freshly sawn timber from the green chain through drying. The same needle probe and 16-group calibration as the MT730, with the range and recordkeeping a production operation needs.
$1,695.00
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.
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.
