AW-MO Wood Moisture Meter

Analog Pin-Type Wood Moisture Meter — No Longer Manufactured

The AW-MO was a rugged, analog wood moisture meter built around a 4-needle probe and a direct-reading meter scale. With no display electronics to set up, it gave a fast moisture reading the moment the probe was driven into the wood.

  • Analog simplicity: Direct needle-gauge reading with zero menus or modes
  • 4-needle probe: Penetrating resistance measurement for solid lumber
  • Field-rugged: Battery-checked, strap-equipped, built for the yard and the shop

Description

The Rugged Analog Meter for a Fast Moisture Check

The AW-MO answered a single question simply and reliably: how wet is this wood? Its 4-needle probe and analog meter scale delivered a direct moisture reading without modes, menus, or setup. Zero the needle, drive the probe, read the scale. For yards, shops, and operations that valued durability over data logging, it was a dependable workhorse.

What the AW-MO Did

  • Direct analog reading: A uniform meter scale showed moisture content the instant the 4-needle probe made contact, with no digital processing.
  • Penetrating resistance method: The needle probe measured DC electrical resistance through the wood for a true internal moisture value.
  • Built-in battery check: A dedicated switch position confirmed sufficient voltage before measurement, avoiding bad readings from weak batteries.
  • Working range to 35%: Covered the practical drying and storage moisture band on a dry-weight basis.

The Current Pin-Type Meter

Kett’s resistance moisture line has moved from analog scales to digital precision, adding automatic temperature compensation, selectable wood-group calibrations, averaging, and alarm functions.

Need a current pin-type wood moisture meter? The MT730 Wood Moisture Meter replaces the AW-MO with a digital display, automatic temperature compensation, and 16 wood-group calibrations.
