Fits non-destructive moisture screening where you need an Extech MO280 pinless meter with 0–99% readings, 0.75 in (20 mm) sensing depth, and 10 selectable wood types.
Key advantages
- Sensor — Non-penetrating electromagnetic pad
- Range / resolution — 0 to 99%; 0.1% max resolution
- Depth — 0.75 in (20 mm) below surface
- Wood types — 10 selectable wood types / measurement ranges
- Calibration — Automatic internal test and calibration; 9 V power
Typical applications
- Flooring and wood screening without pin holes.
- Building survey pinless checks.
- Comparing moisture across material groups.
Selection guide
- Wood type — Select correct group
- Depth — 20 mm capability vs wall thickness
- Pinless vs pin — Surface finish constraints
- Operating — 32 to 122 °F; 0–60% RH
Common mistakes
- Comparing pinless % directly to pin %WME without correlation.
- Wrong wood-type selection.
- Metal behind the surface skewing readings.
