MR77: Rugged, Feature-Packed Moisture for the Toughest Water Restoration Jobs
The new FLIR MR77 is a durable, all-in-one moisture meter that has the flexibility of both a pin-less sensor and a wired pin probe. The MR77 gives you the ability to take moisture readings as deep as 0.75-inch underneath the surface of a range of wood species and building materials. The meter is accurate, reliable and it’s also tested to survive a 2 meter drop.
The FLIR MR77 moisture meter exceeds expectations by delivering advanced measurements that disaster restoration and water damage professionals need on the job-site. The meter has a rugged design that doesn’t break your stride: easy to swap temperature and humidity sensors (field replaceable) are engineered to reduce downtime so you don’t fall behind on your schedule.
What’s in the Box?
The MR77 Moisture Meter comes with a 9V Battery, User Manual/CD, Temperature/RH Sensor, a Wired Pin Probe with 30-inch cable and a Limited Lifetime Warranty
The MR77 offers comprehensive capabilities for moisture-related repairs and inspections. In addition to a non-invasive, 'pin-less' moisture measurement system for damage-free testing, the MR77 also includes a remote pin-type probe with 30” cable for contact moisture readings when necessary.
The jumbo LCD display is backlit by a bright white LED. It is easy to read, displaying moisture, humidity and air temperature levels. It also includes a bargraph for at-a-glance analog style measurements as you scan walls, ceilings, floors and other building material surfaces for changes in moisture.
The FLIR MR77 represents the next generation of disaster-restoration testing equipment. The meter works with FLIR Tools Mobile app to connect it to your compatible smartphone and tablet via Bluetooth. METERLiNK technology also wirelessly embeds moisture readings right on the image of your FLIR Thermal Camera. These mobile tools enable technicians and site managers to datalog, share findings with colleagues, and easily create reports.
The MR77 is so much more than a water-damage restoration contractor’s moisture meter.
The FLIR moisture meter eliminates toolbox clutter by providing the added functionality of several additional meters built right in, adding one-meter convenience and tremendous value to your purchase investment. In addition to moisture sensors and useful high/low alarms, the meter also measures temperature, relative humidity and a number of other valuable diagnostic metrics giving you incredible insight into site conditions and necessary repairs.
The MR77 incorporates a laser-spot IR (infrared) thermometer (with an easy-to-aim laser indicator) to help take rapid point-and-shoot spot temperatures of surfaces under restoration. The IR thermometer measures a 1 inch spot from 8 inches away. The IR thermometer also plays a role in monitoring for condensation hazards by factoring surface temperatures and dew point.
Hygrometer / Psychrometer: Very few moisture meters also double as a hygrometer. The durable, do-it-all MR77 measures ambient temperature to help you quickly check job site temperatures without an additional thermometer. It also provides relative humidity readings and calculates dew point and mixing ratios.
The MR77 is invaluable for calculating vapor pressure (kPA) as well as water vapor in Grains per Pound and Grains per Kilogram.

My unit is heading to Flir for service because the pinless moisture meter is reading over 20% throughout structures while the pinned shows zero.
one issue I have with this unit is that in pinned mode if moisture is less than 7%, it will read zero. That makes you have to guess at lower moisture levels.
The unit is rugged and feels good in hand. My customers really like to be able to "see" what I'm looking for before we open walls. That being said, the ir camera is the most basic Flir offers so I also purchased a Flir One which has a better camera and using it with a IPad, customers really like the better resolution as do I.
I will update my review after I get my unit back, I really wanted to give 3.5 stars here but didn't have that option.
Also, you need to dive into the root software for the basic operating instructions (hook up the meter to a computer and read what's on the unit). This is the only place you'll find the list of wood species by Group number. Really all very non-intuitive.
Finally, when updating the firmware you must use a PC (Windows) computer rather than Mac, otherwise it won't take.
The unit is nice and robust, and has a lot of clever features. Just get the firmware update and it will work ok.
