CRITICAL FLAW ALERT!
This meter exhibits a critical flaw—namely its inability to read below 8% moisture content. This flaw renders the meter essentially unusable for a number of common applications, including for flooring installations and furniture making. We deducted one star from our overall rating to reflect this critical flaw.
The Extech MO220 is a pin-style, conductivity moisture meter specifically designed for wood applications though it also measures moisture in other building materials.
It scored reasonably high in accuracy tests when measuring moisture content (MC) in the mid-range. However, this meter and its heavy duty probe accessory are incapable of taking readings when the MC is 7% or below.
