The FLIR MR277 is an accurate, easy-to-use, all-in-one tool for quickly locating moisture and building envelope issues. This professional moisture meter combines the advantages of Infrared Guided Measurement (IGMTM) with FLIR Multi-Spectral Dynamic Imaging (MSX®) and advanced environmental sensors to help you locate, identify, and document problems. The integrated pinless moisture sensor provides fast, non-invasive readings which you can then confirm with the external pin probe. Features such as the built-in hygrometer and the field-re- placeable temperature/relative-humidity sensor expe- dite troubleshooting, while METERLiNK® allows you to connect to mobile devices and upload data to the FLIR Tools® app for reporting.
