Key Features Of FLIR MR55 Moisture Meter

1. Pin-Based Measurement with Accurate Material Grouping
The MR55 uses integrated pin electrodes to directly measure moisture in various substrates. For wood, it provides highly accurate readings between 7% and 29% with ±2% MC accuracy, and reference readings up to 99% for both wood and building materials. It’s preprogrammed with 11 distinct material groups—1 to 9 for different types of wood and 10 to 11 for masonry and construction substrates—ensuring more reliable results based on the type of material being tested.

2. Bluetooth Connectivity via METERLiNK for Smart Reporting
Built-in Bluetooth Low Energy (BLE) allows the MR55 to connect wirelessly to the FLIR METERLiNK app, giving you the power to log and export moisture readings directly to your smartphone or tablet. This eliminates manual entry, streamlines reporting, and enables better tracking of jobsite progress—perfect for professionals who need efficient digital documentation.

3. Durable Design with Integrated LED Work Light
Constructed from impact-resistant plastic and built to endure harsh environments, the MR55 can handle drops up to 2 meters and daily wear-and-tear. It includes replaceable 10 mm electrodes and a built-in white LED light, which helps you inspect dark or hard-to-reach areas without needing a separate flashlight.

4. High-Visibility LCD with Group and Battery Indicators
The MR55’s multifunction LCD screen is backlit for easy visibility in both daylight and low-light conditions. It displays real-time moisture levels, active group numbers, and a 4-bar battery status indicator—making it easy to keep track of important information at a glance without interrupting your workflow.

5. Extended Battery Life with Auto Shut-Off Functionality
Powered by two standard AA batteries, the MR55 offers up to 70 hours of use before needing a recharge. With its 20-minute auto power-off feature, you conserve battery life when the tool is left idle—giving you extended uptime across multiple inspection days without worry.

Why You’ll Love the FLIR MR55 Moisture Meter

2. Work Smarter with Wireless Integration
Ditch the clipboard and streamline your inspections by pairing the MR55 with your smartphone or tablet. The FLIR app provides instant report sharing, measurement logging, and project organization that fits seamlessly into modern digital workflows.

3. Compact and Tough Enough for Any Jobsite
Weighing only 160 grams and measuring just over 7 inches, the MR55 is easy to carry and store. It’s IP40-rated for protection from dust and built to handle rough handling, giving you reliability in both indoor and outdoor environments.

4. Designed for Daily Use Without Downtime
Quick to power up and easy to operate, the MR55 has intuitive controls, a visible battery meter, and a robust build that resists damage. Whether you’re doing a dozen inspections a day or an extended water damage assessment, it won’t slow you down.

5. Everything You Need Right Out of the Box
The MR55 ships with two AA batteries, integrated and replaceable electrode pins, and full documentation. It’s ready to work the moment you unpack it—and backed by FLIR’s 3-year limited warranty, offering long-term peace of mind.

How to Use

1. Insert Batteries and Start the Device
Begin by installing two standard 1.5V AA batteries into the compartment. Press the power button, and the large backlit LCD will come alive, showing a clear interface. This screen includes your moisture readings, battery level, and material group indicator, helping you start work right away.

2. Choose the Right Material Group
The MR55 supports a total of 11 material groups—1 to 9 for different wood types and 10 to 11 for various building materials like drywall or concrete. Select the right group from the menu using the navigation buttons. This ensures you’re getting accurate readings calibrated for that specific surface type.

3. Take Readings with the Integrated Pins
Firmly press the replaceable 10 mm electrode pins into the material. For wood, you can measure from 7% to 29% with ±2% MC accuracy; higher readings are for reference. For materials like cement or drywall, the meter offers results across the 1% to 99% range using groups 10 and 11.

4. View and Record the Results
The LCD displays real-time readings, group number, work light status, and battery level. Each measurement updates instantly and remains visible even in dim lighting. Thanks to the Bluetooth BLE connectivity, you can also send data wirelessly via METERLiNK to compatible mobile apps.

5. Use the Work Light for Dark Spaces
The built-in white LED work light helps you see surfaces clearly in dark basements, attics, or wall cavities. It automatically activates during use but can be toggled on or off manually. This feature ensures safe and accurate readings in every environment.

How to Take Care

1. Clean the Probes and Device Gently
Use a soft, dry cloth to wipe off the metal pins after each use. Avoid using water or cleaning liquids directly on the unit, especially near the display and pin area. This prevents corrosion and keeps your readings consistent.

2. Keep the Device Away from Water and Dust
The MR55 has an IP40 rating, meaning it’s protected against solid objects but not moisture. Avoid using it in wet conditions or dusty construction zones without proper protection. Store it in a pouch or case when not in use.

3. Remove Batteries for Long-Term Storage
If you won’t be using the device for more than a few weeks, remove the AA batteries. This prevents any risk of leakage or corrosion inside the battery compartment, which could otherwise damage the internal circuitry.

4. Replace Worn Pins on Time
The integrated 10 mm pins are replaceable. If you notice inconsistent or fluctuating readings, it may be time to install new pins. Always use FLIR-recommended components to maintain accurate performance and warranty validity.

5. Store in a Safe Temperature Range
The device operates well between 0°C to 50°C (32°F to 122°F). For storage, avoid extremely hot or cold environments like car trunks or rooftops. Keep it in a cool, dry cabinet to preserve accuracy and battery health.

Safety Tips

1. Never Test on Electrical Circuits
This is a moisture meter, not a voltage tester. Never insert the pins into wires, sockets, or live panels. Doing so may result in electric shock or permanent damage to the device.

2. Don’t Use with Wet Hands or Surfaces
Avoid using the device when your hands or the tested surface is dripping wet. This could lead to skewed readings or risk of internal moisture damage. Dry off the area before taking any measurements.

3. Avoid Dropping or Impact
While the MR55 has passed a 2-meter drop test, continuous abuse can still degrade accuracy. Handle with care and avoid tossing it into tool bags or onto hard surfaces without protection.

4. Use Only AA Batteries
Only use standard 1.5V AA batteries. Mixing battery types or inserting non-standard cells could damage the electronics or cause overheating, especially during extended use.

5. Keep Out of Children’s Reach
This is a professional tool intended for use by trained personnel. The metal pins can be sharp, and the device may be damaged if dropped or mishandled by children. Always store it safely.
