Compatibility & requirements

For home buyers assessing a property, tenants checking for signs of damp, inspectors and floor fitters, this meter provides a way to investigate moisture without driving pins into the surface. Its non-invasive design is suitable for checking walls, floors and ceilings while keeping finished wood, masonry and décor intact.

Choose from five modes to match the material: INDEX for general readings, or dedicated settings for wood, plaster, cement and concrete. The separate plaster and cement modes are useful when checking typical plastered walls. With a scan depth of 5–40 mm, the meter can assess areas beneath plaster, render and floor coverings, helping you look beyond the immediate surface.

Readings are relative, making the meter useful for comparing areas during a survey. The tri-colour display flags Dry, Risk or Wet at a glance, while the data-hold function lets you retain a reading for easier reference. Visual and audible alarms alert you when moisture exceeds the set limit, adding a clear signal as you scan.

How to use it

At start-up, calibrate the meter in open air with the sensor clear of your hands and other objects. Then select the mode that matches the material and scan the area you want to assess. Keep metal away from the scan area within the meter’s 5–40 mm depth range, as it can affect readings.

For a practical room check, compare readings across different points on a wall or floor rather than relying on one spot. The relative readings and back-printed reference chart help you make those comparisons, while the colour display and alarm make areas that warrant closer attention easier to identify. Use data hold when you want to refer back to a reading as you move around the space.

The rechargeable lithium battery is topped up through the Type-C port, so the meter is ready for repeat inspections without disposable batteries. The supplied storage bag keeps the meter and its accessories together between checks.

Final verdict

The Proster PST276-US is a practical choice for non-destructive moisture checks across common building materials. Its five material modes, scan depth of 5–40 mm and quick-to-read Dry, Risk and Wet display support a straightforward survey of walls, floors or ceilings. For property checks, fitting work or routine damp assessments, it offers useful comparative readings without piercing finished surfaces.
