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.
Pin Moisture Meters
The Lignomat Mini DX/C moisture meter comes with the option of using a hammer probe accessory for obtaining deeper measurements within the wood sample. However, we found the hammer probe’s pins to be of poor quality. A large number of them broke during testing and had to be replaced.
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.
The Protimeter Surveymaster hammer electrode is an optional accessory that facilitates measurement of moisture content deep within the wood. It provides reasonably accurate readings though accuracy above 20% tends to be somewhat less.
The Protimeter Surveymaster offers several accessories, including the push cable reviewed here.
The Tramex PTM 6005 is a digital pin meter that uses resistance technology for measuring moisture. It features a built-in socket that accommodates an array of optional external electrodes and insulated pins for measuring moisture content at various depths in the wood.

CRITICAL FLAW ALERT!
This meter exhibits a critical flaw—namely its inability to give reliable readings below 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.
