FLIR MR277, Digital, Square, 7.11 cm (2.8"), Li-Ion, 3.7 V, 0 - 50 °C

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 confirm with the external pin probe.
Features such as the built-in hygrometer and the field-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
- Clearly see areas of concern with a highperformance 160x120px thermal imaging sensor
- Quickly find suspected problems with IGM technology
