The MR277 is the first FLIR building inspection system to combine the advantages of Infrared Guided Measurement
(IGM) and our patented Multi-Spectral Dynamic Imaging (MSX) with advanced environmental sensors to help you
quickly locate, clearly identify, and easily document problems. IGM technology and a laser pointer isolate the area
where you can use the integrated pinless moisture sensor for non-invasive readings or external pin probe for
invasive measurements. With automatically calculated environmental readings and a field-replaceable humidity/
temperature sensor, the MR277 lets you finish the job and minimize downtime.
Connect to external devices with METERLiNK® and use FLIR Tools® to enhance troubleshooting and reports.
