CRITICAL FLAW ALERT!
This meter exhibits a critical flaw—namely it appreciably under-reports moisture content in wood below about 12% moisture content. This flaw renders the meter essentially unusable for a number of common applications, including for flooring installations and furniture making. We deducted two stars from our overall rating to reflect this critical flaw.
The Lignomat Mini DX/C is a pin moisture meter with two sets of pins. Unfortunately, the pins are too short for anything other than measuring moisture near the surface of the wood.

The Protimeter Surveymaster comes with several probe accessories and features two modes of operation. One is a search (pinless) mode that quickly scans samples and provides a relative reading using a capacitive-coupled sensor. The other is a measurement (pin) mode that provides moisture content readings using two pins inserted into the sample.
