FLIR MR77 Moisture Meter with Pin/Pinless Sensors, IR Thermometer, Hygrometer and Bluetooth METERLiNK

The FLIR MR77 combines pin and pinless moisture measurement with an integrated infrared thermometer and hygrometer, eliminating the need to switch between separate tools on restoration or inspection jobs. Its field-replaceable temperature and humidity sensor keeps downtime low, while Bluetooth METERLiNK streams readings directly to FLIR cameras for documented reports.

Highlights

• Dual moisture detection: invasive pin probes (0–99% WME) and non-invasive pinless scanning up to 19 mm deep
• Built-in IR thermometer with 8:1 distance-to-spot ratio covers -20 to 200 °C
• Measures relative humidity (0–99% RH) and air temperature, then calculates dew point and vapor pressure
• Backlit LCD with adjustable auto power off and data hold for convenient one-handed use
• Powered by a single 9V battery and supplied with pin moisture probe, lanyard and manual

In daily use

Switch between pin mode for wood and building materials, pinless mode for quick scans behind finishes, and the IR thermometer for surface temperatures. The relative humidity sensor tracks ambient conditions, and dew point calculations help assess condensation risk. Bluetooth connectivity via METERLiNK lets you embed moisture readings into thermal images for clear client documentation.
