FLIR MR277 Building Inspection System with Moisture Meter
- Integrated thermal imaging, moisture detection, and environmental sensing
- Pinpoint building issues faster with the FLIR MR277
The FLIR MR277 is a professional building inspection system that combines accurate moisture detection, thermal imaging, and environmental sensors. Designed to help contractors, facility managers, and building inspectors find hidden issues faster.
The FLIR MR277 helps you diagnose problems quickly. It also improves your workflow. It combines everything into one rugged and reliable tool.

Using FLIR‘s Infrared Guided Measurement (IGM) and MSX image enhancement, the FLIR MR277 helps you find issues fast. It guides you to moisture, insulation gaps, and air leaks. With an onboard laser pointer, crosshairs, and a high-resolution thermal sensor, you can pinpoint building faults without guesswork.
You can find the exact location without invasive inspections.
Capture thermal and visual data with MSX clarity. Use the built-in pinless moisture sensor for quick scans. Use the included external pin probe for verified, targeted readings. The replaceable temperature and humidity sensor ensures long-term operation with minimal downtime.
The FLIR MR277 includes Bluetooth and works with FLIR Tools and METERLiNK. This makes it easy to create clear reports. You can also share findings while on the go. Whether you face rising damp, structural leaks, or ventilation issues, the FLIR MR277 is an all-in-one tool.
The FLIR MR277 makes building checks easier by combining thermal imaging, moisture detection, and environmental monitoring in one tool.
