Lutron Concrete and Wood Moisture Meteris a metric tool which estimates the amount of moisture present in the concrete and construction materials. The Concrete and Wood Moisture Meter sense the water molecules present inside the concrete and wood layers and calculate the water volume. The moisture level is displayed on the digital screen. The Wood Moisture Meter consists of a pen-like structure which is used to sense the water content at the deeper levels. The pointer is connected to the moisture meter which contains an LCD digital display and the power and operating buttons below it. The moisture meter usually operates on a battery which provides the constant power supply to the device.
