MESTEK Pinless Moisture Meter for Wood, Walls & Drywall, Digital Moisture Detector, Concrete Moisture Meter & Firewood Reader, Detects up to 40mm Below Surface with 3-Color LCD Display, Audible Alarm

MESTEK’s WM700 / WM710 series are handheld moisture meters commonly sold as pinless (inductive) or hybrid (pinless + optional pin probe) models for building inspectors, flooring contractors, restorers and DIYers. They use electromagnetic (inductive/dielectric) sensing to detect subsurface moisture under finished surfaces (wood floors, drywall, plaster, concrete) without puncturing the surface, and many units include a color LCD, audible alarm and simple material presets (softwood / hardwood / wall / masonry). Typical effective sensing depth is in the ~20–40 mm range depending on the exact model and the material under test.

Key Features

【100% Non-Destructive Measurement】: No need to insert electrodes or probes into the material to be measured, the high-frequency waves emitted by the sensor of MESTEK moisture meter can penetrate about 40mm (1.5inch) into masonry, and the humidity measurement will never damage the surface of the object. The ball probe allows users to easily measure in tight areas without leaving marks, and can easily measure the moisture content in corners, uneven surfaces and around baseboards.
【Automatic Calibration & High-precision Measurement】: Press the “MEAS” button after the moisture meter is turned on, and it only needs to wait for 3 seconds to complete the automatic calibration and start the measurement.Adopting high-precision alloy probe and high-performance processing chip, the measurement is accurate and responsive, and the measurement range reaches 0.0-100.0 with resolution: 0.1%.
【3-Color LCD Display】: The moisture meter is equipped with a 3-inch HD color screen with three color analog bars and indicates "DRY", "RISK" and "WET" status by "Green", "Yellow" and "Red" respectively, which is very beautiful and intuitive, and very easy to read in low light conditions.auto shut-off function: 30 minutes after no operation, battery is more durable.
【Wide Range of Uses】:Suitable for testing the moisture content of wood and building materials such as wallboard, slate, tiles, cardboard, plaster, concrete and mortar, as well as for repairing water leaks, checking the moisture content of bedroom walls, floor tiles or caravans, etc. by checking suspicious water stains with a moisture tester around the house, You can determine whether the area is wet (a perfect breeding ground for mold),but not tell the mold directly
【Comfortable & Easy to Carry】:The side of the moisture meter is embedded with soft rubber, which is comfortable to touch. There is a cloth bag in the package, which is more convenient to carry and store. Please note that when measuring, please try to hold the lower part of the meter, otherwise wet hands may affect the measurement results. If any technical or quality issue, please do not hesitate to contact and we will repsonse within 24 hours

Key Considerations

1

Measurement method: Pinless (non-destructive induction/dielectric) — some WM700 variants add an external pin probe for verification.

2

Effective depth: Manufacturer/reseller pages list nominal depths around 20–40 mm (≈0.8–1.6 in) for the pinless sensors — actual depth varies with substrate.

3

Material modes & calibration: Many units offer presets for softwood, hardwood and building materials (wall/concrete) — pick the correct mode for better relative readings.

4

Display & alarms: Color or backlit LCD, numeric/graphic readout, tri-color bar or icons and an audible alarm for fast triage.

1

The workflow most pros use: (1) sweep large areas in pinless mode to map suspicious zones (watch LEDs/alarms), (2) mark/hot-spot those areas and freeze/save readings (HOLD) or photograph, (3) verify with a pin probe or more formal testing where numeric percent values or contractual acceptance are required. This minimizes unnecessary surface damage while ensuring verification where it matters.

These factors represent the most critical aspects that will impact your satisfaction with this product.

Fast Scanning and Easy-to-Read Display
2025-12-08T08:18:44.590Z

The pinless design makes it quick to scan walls, wood, and flooring without leaving marks. Readings update instantly and the color-coded LCD is simple to understand at a glance. A useful tool for checking moisture before repairs or painting.

Frequently Asked Questions

Final Verdict

MESTEK’s WM700 / WM710 series offer practical, low-cost pinless (and in some SKUs hybrid) moisture meters that are well suited for fast, non-destructive surveys of wood, drywall, plaster and concrete. Their strengths are speed, no surface damage, clear visual/audible triage aids and simple workflows (scan → mark → verify). Their limits are the usual ones for pinless technology: nominal sensing depth varies with materials, readings can be influenced by metal or layered constructions, and they should be complemented by pin meters, thermal imaging or standard concrete tests when you need precise, contract-grade moisture numbers.
