All mini-Lignos are calibrated to measure wood moisture in percent.
The differences are in measuring range, additional materials to be measured, number of wood species corrections and the capability to add a hand probe or extension cable (C-Models). Besides measuring wood, the mini-Lignos S/D and S/DC, DX and DX/C have calibrations for standard drywall and water resistant panels, exterior and interior panels as well as a reference scale to be used for concrete and other materials.
The Ligno-VersaTec and Lignometer K should be considered as more advanced moisture meters with a wider moisture range and more corrections for different wood species and other materials . And, the Ligno-VersaTec is also a pinless and RH meter.
