Product Information

The FLIR MR77 Moisture Meter is a rugged and exceptionally durable all-in-one meter that comes loaded with advanced features to make your job easier.


When we describe this meter as durable, we’re not kidding around. The MR77 is encased in a double-molded, shock-resistant rubberized case that has been drop-tested to 2 meters (6 feet). So you don’t have to worry about the heavy bumps and bruises that come from rough restoration work affecting this meter’s performance.


The MR77 features pin and pinless moisture detection capability. The built-in pinless moisture sensor is designed to capture accurate moisture readings up to 0.75” below material surfaces without causing surface damage. The 30” wired pin probe allows you to take more in-depth measurements in hard-to-reach areas.


The integrated laser-spot IR thermometer allows you to quickly capture spot temperatures. In addition, the MR77 also measures air temperature, dew point, relative humidity, and GPP.


The temperature and relative humidity sensor can be conveniently replaced in the field. So if it starts to go out of calibration, you can easily replace it without any downtime or lost productivity.


All readings from the MR77 are displayed on the large, clear LCD screen. It simultaneously shows moisture, relative humidity, and air temperatures, showing you at a glance the critical information you need to know on the job.


The FLIR M77 features Bluetooth connectivity, allowing you to wirelessly upload data to FLIR Tools Mobile software. This meter also features METERLiNK, which allows you to embed moisture readings into thermal images from METERLiNK-enabled FLIR IR cameras for enhanced documentation and reporting capability.
