A moisture meter is an instrument used to evaluate moisture in materials. Different instruments and settings provide different kinds of readings.
What this means at your property
Pin and non-invasive meters interact with materials differently. Metal, material composition and measurement depth can affect interpretation. A single high reading is a reason to investigate the location, not a complete explanation of the leak or the repair required.
What should I ask when shown a reading?
Ask which material and setting were used, what the scale means and what comparison supports the interpretation. Keep the marked measurement locations with the drying record so later checks can be compared meaningfully.
