The ohm is the unit of electrical resistance. Resistance is one of several electrical properties that may be measured during equipment or circuit evaluation.
What this means at your property
Some moisture instruments infer conditions from electrical behavior, but an electrical reading needs the correct instrument, material and interpretation. A number expressed in ohms should not be treated as a universal moisture percentage or a declaration of safety.
Who should interpret electrical findings after a leak?
Have affected wiring and equipment evaluated by a qualified electrician. For a moisture assessment, ask the restoration team to identify the meter scale and material setting rather than comparing unlike measurements.
