Wood Species Correction Table - Pin-Type Moisture Meters
For pin-type moisture meters that do not have wood species corrections built in, manual correction is required. Delmhorst uses Douglas Fir, the USDA standard, as the basis for all wood calibrations. Because the electrical characteristics of different species vary, all species read differently at the same moisture content.
   
Wood Species Correction Table - TechScan Pinless Moisture Meters  Download Now
Measurements obtained with pinless (capacitance type) moisture meters such as TechScan are greatly influenced by the specific gravity of the wood. Wood with higher specific gravity produces higher moisture readings than materials with lower specific gravity at the same moisture content. Since TechScan is calibrated for wood at a specific gravity (SG) of 0.46, a correction is required when measuring wood species with SG values other than 0.46. Refer to the owner's manual for more information on SG corrections.
   
Temperature Correction Table
For meters that do not have temperature corrections built in, manual correction is required. As wood temperature increases, its electrical resistance decreases and indicated moisture content rises. Lower wood temperatures result in lower indicated moisture content. If the wood temperature, which is typically the ambient temperature, is between 50°F/10°C and 90°F/32°C, there is no need to apply a correction.
   
Pin Correction Table
For meters that do not have pin corrections built in, manual correction is required. The default calibration on our pin meters was made with non-insulated pins that penetrate 5/16 inch. Since insulated pins read slightly lower than noninsulated ones, refer to this correction table when using an electrode with insulated pins, such as the 26-ES.
