Choose between our 7250 moisture meter with integrated pins for single-hand checks, or our 7000 moisture meter with interchangeable probes for dual-handed checks. The 7000 damp tester is compatible with a range of probes for reaching deep into wood and walls.

ETI Moisture Meters for Professionals

Moisture meters, also known as damp meters, enable building professionals and tradespeople to measure the moisture levels in construction materials such as wood, plaster and concrete.

A high moisture content in buildings or materials can cause issues such as rot and mould. Measuring moisture levels using a damp meter is the best way to determine whether a material is fit for use or whether a building is structurally sound.

A wood moisture meter ensures quality and durability and prevents issues like warping and decay. ETI's portable, pin-type damp detectors allow accurate moisture measurement of different materials. They have a setting for accurate wood measurement, as well as concrete, plaster, and reference.

Featuring a colour-coded scale, users can quickly and easily see whether moisture levels are at a low, medium or high level.

Frequently Asked Questions

What is a moisture meter?

A moisture meter measures the amount of moisture within a material. It helps identify dampness, prevent damage, and ensure materials are within acceptable limits.

How does a moisture meter work?

Moisture meters either use pins to measure electrical resistance within a material or scan the surface using pinless technology. Both methods provide quick, reliable readings.

What is a moisture meter used for?

Moisture meters are used to check moisture levels in materials such as wood and building surfaces. They help prevent damage, improve quality, and support maintenance and inspection tasks.

What’s the difference between pin and pinless moisture meters?

Pin meters measure moisture internally using probes inserted into the material. Pinless meters scan the surface without causing damage, making them ideal for quick checks and finished surfaces.

How to use a moisture meter?

Read our step-by-step moisture meter guide to learn how to use ETI damp testers.

What’s the best moisture meter for wood?

The best pin-type moisture meter for wood is the ETI 7000. It has a high ±1% moisture accuracy and features interchangeable probes for maintaining accuracy over time.

It’s also compatible with the ETI Hammer Probe for reaching deeper into thicker and denser woods.

Do moisture meters need calibration?

Yes, regular checks and calibration help ensure readings remain accurate over time. This is especially important in professional and industrial applications.

You can send your moisture meter to us for 3-point traceable recalibration at our UK laboratory. Learn more about our calibration services.
