Data Sheet
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 (IGM™) 
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 conrm with the external 
pin probe. Features such as the built-in hygrometer and 
the eld- replaceable temperature/relative-humidity 
sensor expedite troubleshooting, while METERLiNK
®
allows you to connect to mobile devices and upload 
data to the FLIR Tools
®
 app for reporting.

LOCATE BUILDING 
PROBLEMS FASTER
Easily investigate the source of moisture build-up 
and building envelope issues
•  Quickly scan for moisture with the integrated 
non-invasive pinless sensor
•  Capture exact measurements with an external 
pin probe (included) and wide range of 
optional moisture probes
