Lignomat SDM Ligno-ScannerSDM Moisture MeterxLigno-Scanner SDM Moisture Meter Digital display Rugged design for easy operation Wide range wood scale (5-60%) Reference Scale for non-wood building materials (0-99) Built in corrections for 71 wood group Automatic shut off HOLD feature ' measuring depthLigno-Scanner SDM Moisture MeterThe Ligno-Scanner SDM clearly outperforms most pinless moisture meters on the market today. The meter has 2 independent sets of calibrations one for measuring 1/4? deep and one for measuring 3/4? deep. Dual-depth settings are available for different wood species, drywall, reference scales for concrete and other building materials. The bamboo calibration settings (flat and vertical grain and strand, carbonized) are for a measuring depth of 1/4?.Why choose a Ligno-Scanner SMD from Lignomat:Lignomat's unique measuring technology assures calibration accuracy, reliability and repeat-ability backed by a 2-year warranty on all moisture meters. The Ligno-Scanner SDM pinless moisture meter has very unique features such as calibrations to measure the moisture in bamboo.The moisture meter of choice for multi-material applications: flooring, restoration, inspection and construction.The measuring depth of a pinless meter is crucial. Moisture readings are too low, when the Scanner is placed on a work piece which is thinner than the measuring depth. Scanners never measure any deeper than the measuring depth.The entire measuring pad has to be on a flat and smooth surface for accurate readingsSpecies Corrections for Ligno-Scanners and Ligno-VersaTec correlate directly to the Specific Gravity. Example: For a specific gravity of 0.57 (0.57g/cm 3 )set species # 57. Specific Gravity for most wood species can be found on the Internet. We also include a Species Chart with recommended settings.
