FLIR MR277: Professional Pin/Pinless Moisture Meter, Thermal Imager & Hygrometer — Find Problems Fast, Fix Them Faster

The FLIR MR277 puts four professional instruments in one rugged tool: a thermal imager, pinless moisture sensor, pin probe, and hygrometer. Scan surfaces non-invasively, confirm readings with the pin probe, monitor environmental conditions, and document everything wirelessly — all without swapping tools or leaving the job site.

Included with the MR277-

• 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

Key Features of the Flir MR277 Moisture Meter-

• FLIR Thermal Imaging Sensor — Detects heat and temperature differences behind walls, ceilings, and floors, guiding you directly to moisture, air leaks, and insulation failures without opening up surfaces
• FLIR MSX Image Enhancement — Overlays sharp physical details onto thermal images so you can see exactly where on the wall, ceiling, or floor the problem is — no guesswork about location
• Laser Pointer & Crosshair — Points to the exact spot you're measuring so there's no confusion between you, your crew, or your client about where the issue is
• Pinless Moisture Sensor — Scans large surface areas quickly without puncturing drywall, flooring, or other materials — ideal for fast triage and scoping a job
• External Pin Probe (Included) — Penetrates the surface to get a precise moisture reading at depth, confirming what the pinless sensor flagged and giving you defensible numbers for your report
• Integrated Hygrometer & Environmental Sensors — Measures ambient temperature, relative humidity, and dew point simultaneously so you can assess atmospheric drying conditions on the spot
• Field-Replaceable Humidity & Temperature Sensor — If the sensor wears out, you swap it yourself on the job site — no downtime, no sending the unit in for repair
• Bluetooth & FLIR Tools Reporting — Wirelessly syncs readings and thermal images to your phone or tablet so you can generate and share inspection reports before you leave the building 

Mode 1: Thermal Imaging -

Detects heat anomalies behind walls, ceilings, and floors to locate moisture, air leaks, and insulation failures without opening up surfaces.

Mode 2: Pin & Pinless Moisture Readings -

Scan surfaces non-invasively with the pinless sensor for fast triage, then confirm exact moisture levels with the included pin probe for precise, defensible readings.

Mode 3: Hygrometer & Environmental Monitoring -

Measures ambient temperature, relative humidity, and dew point so you can assess drying conditions on the spot.
