SDM Intelligence · Diagnostic Method

How professionals investigate hidden water.

No single camera or meter can replace a structured investigation. The strongest evidence comes from combining observations, screening, measurements, assembly knowledge and repeat verification.

A practical evidence chain

Visual inspection

Start with the source area, visible staining, swelling, material transitions, lower levels and plausible migration paths.

Thermal screening

Use temperature patterns to locate areas that deserve further investigation. Thermal imaging does not identify water directly.

Moisture measurements

Use an appropriate instrument and material context to compare suspicious and apparently unaffected areas.

Assembly access

If evidence and conditions warrant it, selective access may reveal concealed insulation, framing, cavities or interfaces.

Psychrometrics

Temperature, RH, vapor content and equipment performance help explain whether the drying environment is doing useful work.

Repeat verification

Trends and comparison points are more informative than a single isolated number.

Important: A thermal anomaly may have many causes, and a meter reading only has meaning in the context of the instrument, mode, material, reference condition and location. SDM Intelligence should not convert either into certainty that the evidence does not support.
