The MR277 Moisture Meter is a true all in one tool, combining pin/pinless moisture probes, thermal image display, and built in hygrometer/thermometer gauge.
The FLIR MR277 packs everything a building inspector needs into one device. Its pinless sensor scans surfaces quickly and non-invasively, while an external pin probe confirms any findings. Infrared imaging with MSX® enhancement makes hidden moisture problems visible at a glance, and onboard environmental sensors — including a hygrometer and a field-replaceable RH/temperature probe — speed up diagnosis. When it's time to report, METERLiNK® wirelessly syncs data to the FLIR Tools® app.
Included with the Flir MR277 Moisture Meter
- FLIR MR13 Replaceable Temperature and Relative Humidity Sensor
- FLIR MR02 Standard Pin Probe
- Quick start guide
- International USB charger, USB cable, and lanyard
-
Locate Problem Areas Faster
Quickly find moisture, air leaks, insulation voids, and more with thermal imaging that's 4× the resolution of earlier IGM moisture meters.
-
Diagnose Efficiently and Accurately
Pinpoint moisture issues with integrated non-invasive sensor, and capture accurate readings across the problem area with provided external pin probe and optional specialty moisture probes.
-
Do More in Less Time
A single tool accelerates finding issues and documenting problems in one file with thermal and comprehensive visual imagery along with accurate hygrometer readings and laser location.
Overview
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.
