How do I Care for My Moisture Meter?

Moisture meters used for inspection are generally factory calibrated. To keep your meter in good working condition:

  • Store the meter in a clean, dry location
  • Change batteries and pins as needed. Running a moisture meter on low batteries may cause the meter to go out of calibration
  • Keep the electrodes and meter clean by using a biodegradable cleaner sparingly on external parts only

If repairs or re-calibrations must be done on the meter, it is suggested to return the meter to the manufacturer or manufacturer service center for service and re-calibration to original standards.

What type of moisture meter works best for water-damaged structures?

To quickly identify wet areas in walls and floors, pinless meters are easy to use. They offer the convenience of testing a large area quickly and help you determine if further testing is required in certain spots.

On the other hand, a pin-type moisture meter is the best way to identify the exact location of water damage behind walls, in subfloors or in any other area where moisture may be hidden behind another surface. The key to finding hidden moisture is to use an electrode with insulated contact pins. These pins read-only at their uninsulated pin tips, allowing the user to drive the pins into the material at various depths, noting readings at each level of penetration.

How far should I drive non-insulated pins into the wood?

Drive pins into the wood at full depth if possible. At moisture levels below 10%, it is essential to make positive contact with the substrate to get an accurate reading.

Can I use a moisture meter to check for pest infestation?

Yes. A few meter readings in key locations of the structure will quickly indicate if the areas are safe or in danger of infestation. Using pin-type meters for pest control applications is the best way to identify the exact point of infestation behind walls and ceilings. The meters make this possible by detecting moisture in areas where pests can grow and thrive without human interaction. While fungi and mold begin to grow in wood with moisture content around 20%, some species of insects thrive in wood with only 12%MC.
