The FLIR MR12 is a ball-shaped moisture sensor accessory designed to extend the measurement range of the FLIR MR176, MR160, and MR60 moisture meters. Cover a large area in a short time without making a mark, and measure into corners and around baseboards easily. When there’s no clear presence of moisture, the MR12’s ball probe can help you detect moisture below the surface, and determine the moisture migration path from the source.
