Mestek WM700B - non-destructive dielectric moisture meter for near-surface measurements

During the measurement, the instrument determines the dielectric constant of the material and the value displayed is based on this. As with the dielectric constant, the result read on the instrument is dimensionless and is transposed to a value between 0 and 100 for ease of comparison. The result of the measurement is moisture-dependent in the case of a material that can hold water. Air (dry) has a constant of ~1, water ~80. A higher value indicates a higher moisture content. The numerical value is not a percentage moisture content of the material, but a reference: for example, by tracing a wall surface, it is easy to determine the location of a possible leak.

> Professional and Precise, Non-destructive Measurement: The moisture meter with high precision alloy probe and high performance processing chip, accurate measurement, fast response, measuring range up to 0.0-100.0. With data hold function. Without inserting electrodes or probes into the material to be measured, the high frequency waves of the moisture meter can penetrate about 40mm into the masonry, and the moisture measurement will not damage the surface of the object.
> Easy to Use: Measuring depth: Max. 40mm wall depth. Single point measurement can display MAX/MIN value simultaneously. Wet and dry alarm function-WET/RISK/DRY, the alarm threshold can be set automatically according to user requirements. Use the "MEAS" button for calibration after power on. The hold function can be used to record the current reading.

> Widely Applications: The wall moisture detector can be used to measure all kinds of masonry, plaster, wood, concrete, cement, houses, motorhomes and caravans. Even in hard-to-reach places you can still use it to measure. It is an excellent tool for homeowners, builders, carpenters and gardeners, to detect leaks and problems with water ingress. Note: This product cannot measure metals.

> Professional Visibility: The damp moisture locator features a large color LCD display and analog color display bar to make measurements more intuitive, low power alarm and automatic shutdown after 30 minutes without operation.
