The Delmhorst 315CAB-0020/025, when used with optional contact pins, is a great solution for long-term monitoring of wood. This cable connects directly to the MTX using the terminal connection on the MTX.

With pins that are insulated except at the tip, you can obtain core readings which provide a true indication of moisture content at a known depth. The 315CAB0020/025 has a cable length of 25 feet.
