Shaw Moisture Meter Calculator

Shaw Moisture Meter Calculator




Introduction & Importance

Shaw moisture meters are essential tools for woodworkers and carpenters, helping to determine the moisture content of wood. This calculator simplifies the process, ensuring accurate and reliable results.

How to Use This Calculator

  1. Enter the reading from your Shaw moisture meter.
  2. Input the current temperature in degrees Celsius.
  3. Select the wood species from the dropdown menu.
  4. Click ‘Calculate’ to see your results.

Formula & Methodology

The calculator uses the following formula to adjust the Shaw moisture meter reading for temperature:

Adjusted Reading = (Reading – 12) / (1 + 0.002 * (Temperature – 12)) + 12

The wood species’ specific gravity is then applied to calculate the moisture content:

Moisture Content = Adjusted Reading * Specific Gravity

Real-World Examples

Reading Temperature (°C) Wood Species Adjusted Reading Moisture Content (%)
25 20 Pine 24.58 22.12
30 15 Oak 28.85 31.23
22 25 Maple 21.37 27.93
