The Complete Guide To Flir Mr277: Specifications, Pros And Cons, Troubleshooting, And Buying Tips
FLIR MR277 Information
The FLIR MR277 is a building inspection system that combines the advantages of infrared guided measurement (IGM) and FLIR's patented Multi-Spectral Dynamic Imaging (MSX) with advanced environmental sensors to help you quickly locate, clearly identify, and easily document problems.
Here are some of the key features of the FLIR MR277:
- IGM technology helps you isolate the area where you need to take a measurement by superimposing a thermal image of the area over a visible image. This makes it easier to see the exact location of moisture or other problems.

- MSX imaging adds a layer of visual detail to the thermal image, providing you with more information about the structure of the material you are inspecting. This can help you identify problems that would not be visible in a thermal image alone.
- Advanced environmental sensors measure temperature, humidity, and dew point, providing you with important information about the environment in which you are working. This information can help you identify the cause of moisture problems and prevent them from recurring.
- Field-replaceable humidity/temperature sensor allows you to quickly and easily replace the sensor if it becomes damaged or dirty.
- METERLiNK® connectivity allows you to connect the FLIR MR277 to other devices, such as a laptop or tablet, for data logging and analysis.
- FLIR Tools® software provides you with a powerful set of tools for viewing, analyzing, and documenting your thermal images.
The FLIR MR277 is a versatile and powerful tool that can be used for a variety of building inspection tasks, including:
- Locating moisture problems
- Identifying insulation deficiencies
- Inspecting roofing and siding
- Evaluating HVAC systems
- Detecting structural defects
- Identifying fire hazards
The FLIR MR277 is a valuable asset for any building inspector or contractor who wants to quickly and easily find and fix problems.

As you can see, the FLIR MR277 has the highest resolution and effective temperature range of the three products. It also has the best image quality. However, it is also the most expensive. The FLIR MR265 is a good option if you're looking for a high-resolution thermal imager with a more affordable price tag. The FLIR MR160 is the most affordable option, but it has the lowest resolution and effective temperature range.
Here is a more detailed comparison of the three products:
- FLIR MR277: This is the most advanced product of the three. It has the highest resolution and effective temperature range, as well as the best image quality. It is also the most expensive.
- FLIR MR265: This is a good option if you're looking for a high-resolution thermal imager with a more affordable price tag. It has the same resolution as the FLIR MR277, but its effective temperature range is slightly lower.
- FLIR MR160: This is the most affordable option of the three. It has the lowest resolution and effective temperature range, but it still offers a good image quality.
Ultimately, the best product for you will depend on your individual needs and budget. If you need the highest resolution and effective temperature range, the FLIR MR277 is the way to go. If you're looking for a more affordable option with good image quality, the FLIR MR265 is a good choice. And if you're on a tight budget, the FLIR MR160 is still a good option.
FLIR MR277 Pros/Cons and My Thought
The FLIR MR277 is a thermal imaging moisture meter that combines the advantages of Infrared Guided Measurement (IGM) and the company's proprietary Multi-Spectral Dynamic Imaging (MSX) with advanced environmental sensors to help you quickly locate, clearly identify, and easily document problems.
Pros:
- High-resolution thermal imaging: The MR277 has a thermal resolution of 160 x 120 pixels, which is four times better than earlier IGM moisture meters. This means that you can see more detail in the thermal images, which can help you to identify moisture problems more accurately.
- Integrated pinless moisture sensor: The MR277 has an integrated pinless moisture sensor that allows you to take non-invasive moisture readings. This is a great feature for finding moisture problems in walls, ceilings, and other areas where it is difficult or impossible to drill holes.
- External pin probe: The MR277 also comes with an external pin probe that can be used for more invasive moisture readings. This is a good option for finding moisture problems in materials that are difficult to penetrate with the integrated sensor, such as concrete or masonry.
- MSX imaging: The MR277 also uses MSX imaging, which combines the thermal image with a visual image to create a more detailed picture of the area you are inspecting. This can be helpful for identifying moisture problems that are not visible in the thermal image alone.
- Automatic environmental readings: The MR277 also automatically calculates and displays environmental readings such as temperature and humidity. This can be helpful for troubleshooting moisture problems and understanding the conditions that are causing them.
- Field-replaceable humidity/temperature sensor: The MR277 has a field-replaceable humidity/temperature sensor. This means that if the sensor gets damaged or fails, you can easily replace it without having to send the entire unit back to the manufacturer.
- 10-year warranty: The MR277 comes with a 10-year warranty. This is a good indication of the manufacturer's confidence in the product.
