Essential Info

This moisture meter can measure the amount of moisture located in wood materials. It also includes a remote handpress moisture probe for use on hard surfaces. A temperature probe increases accuracy by adding automatic temperature compensation (ATC) to your measurements. The meter automatically calibrates itself so you will get correct readings every time. Its memory contains eight wood groups with calibrations for 170 wood species. Readings are clearly displayed on the LCD display. Two AAA batteries (included) are required for operation. A low battery indicator informs you when battery level gets low. The meter also features adjustable automatic off times to prolong battery life.
