FLIR MR77 Moisture Meter Features

Pinless Moisture Sensor

Capture accurate, non-destructive moisture readings up to 0.75″ below material surfaces using the integrated pinless sensor.

Wired Pin Probe

Monitor moisture levels in hard-to-reach areas using the FLIR MR77’s external pin probe on 30″ wire.

Built-in IR Thermometer

Quickly capture spot temperatures using the non-contact, IR thermometer with laser spot.

Intuitive Display

Large, clear LCD screen simultaneously displays moisture, relative humidity, and air temperatures.

Bluetooth Connectivity

Upload data to FLIR Tools Mobile software so you can easily turn moisture/environmental trending graphs into professional reports.

METERLiNK Compatibility

Embed moisture readings into thermal images from METERLiNK-enabled FLIR IR cameras for enhanced documentation/reporting.


Double-molded, rubberized case is shock-resistant from drops from as high as two meters to bolster reliability and durability.

Rugged Design

Designed to resist contamination, the temperature/humidity sensor is field replaceable to keep the unit in action on the job site.
