What type of moisture meter is recommended for use on most hard surfaces?

Penetrating moisture meter
Non-invasive moisture meter
Digital moisture gauge
Electrical impedance meter

The correct answer is: Non-invasive moisture meter

The recommended choice for use on most hard surfaces is the non-invasive moisture meter. This type of meter is designed to measure moisture levels without needing to penetrate the material, making it ideal for surfaces like concrete, tile, or hardwood where you want to avoid causing damage. Non-invasive meters often use electromagnetic signals or infrared sensors to detect moisture levels right beneath the surface. This capability allows for quick and efficient assessments of moisture content across various hard surfaces without the risk of compromising their integrity. For example, while penetrating moisture meters can provide accurate readings in specific materials by inserting probes, they can also damage the surface being tested. Digital moisture gauges and electrical impedance meters may serve specific purposes depending on the environment, but they don't offer the same level of non-destructive testing suited for hard surfaces as non-invasive moisture meters do. Therefore, non-invasive moisture meters are generally the best choice for this application.
