Wagner Meters MMC210 At a Glance

The Wagner MMC210 is one of the most accurate meters we tested for measuring moisture in different woods. It is a pinless meter that measures moisture without damaging the wood surface and without interference from surface moisture.

Suitable for many wood-related applications, this lightweight and easy-to-operate meter measures moisture in common domestic softwood and hardwood species. This meter offers a HOLD function which “freezes” the reading until the display can be viewed.

This is a well-constructed meter. It comes in a comfortable, compact size and can provide quick, accurate scanning of either lumber or wood flooring. This meter is worth buying.

Pros

  • One of the most accurate meters we tested for measuring wood moisture.
  • Features 7-year manufacturer’s warranty and exceptional customer service.
  • Eliminates interference from surface moisture.
  • Simple, easy-to-use controls.
  • Measurement range is from 5% to 32% moisture content (MC).

Cons

  • No backlight display.
  • No audible or visual alarm.
  • Species adjustment for standard specific gravity range only.

Meter Temperature – 4.7 out of 5.0

Meter temperature had a small effect on this meter’s readings. A low meter temperature of 34.8° F in the presence of low MC increased the reading by 0.5% compared to the room temperature reading. In the presence of high MC, the reading increased 1.2%. A high meter temperature of 110° F in the presence of low MC lowered the reading by 0.7% compared to the room temperature reading. In the presence of high MC, the reading decreased by only 0.2%.

Wood Temperature – 4.0 out of 5.0

Wood temperature had some effect on this meter’s readings, particularly when the MC of the wood was higher. A low wood temperature of 33.6° F in the presence of low MC lowered the reading by 0.5% compared to the room temperature reading. In the presence of high MC, the reading dropped 1.8%. A high wood temperature of 110° F in the presence of low MC increased the reading by 0.5% compared to the room temperature reading. In the presence of high MC, the reading increased 2.4%
