# FLIR MR77 5-in-1 Moisture Meter with METERLiNK # FLIR MR77 5-in-1 Moisture Meter with METERLiNK ## Key Features At A Glance - Series spans pin, pinless, and combination moisture sensing across seven models for wood and building materials - Imaging models add an 80 × 60 FLIR Lepton thermal sensor with IGM to visually guide you to where moisture may be hiding - Bluetooth/METERLiNK plus Micro USB and RJ45 connectivity available on select models for data transfer and sharing - Free FLIR Tools and FLIR Tools Mobile software for reviewing readings, viewing live data, and generating reports - Built-in library of 11 material groups (incl. timbers, drywall, and concrete) on library-equipped models - Field-replaceable temperature/relative humidity sensor on the MR77 and MR176 for environmental readings - Drop-tested durability from 2 m to 3 m across the series - Compatible with FLIR's full line of external pin, impact, hammer, baseboard, wall-cavity, and ball probes FLIR's moisture meter line is a family of handheld instruments for locating and quantifying moisture in wood and common building materials, ranging from a pocket-sized moisture pen to imaging models that combine moisture sensing with a built-in thermal camera. The premium models, the MR176 and MR160, feature IGM (Infrared Guided Measurement) powered by a built-in 80 × 60 FLIR Lepton thermal imaging sensor that visually guides the user to the precise spot where moisture may be hiding. These meters are built for moisture inspection, remediation, and HVAC work, as well as general construction troubleshooting. Applications named across the line include identifying problems behind walls, under floorboards, and in ceilings; collecting and storing moisture data over time from multiple sites; finding and quantifying moisture content in wood and common building materials; and measuring temperature and relative humidity to assess environmental conditions on the job. ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we sell are on hand and ready to ship. ## Brand Heritage FLIR Systems, founded in 1978, was acquired by Teledyne Technologies in 2021. Its thermal imaging and test-and-measurement product lines now operate under the Teledyne FLIR brand. ## Compare Other Models in This Series FLIR's moisture meters are a single family of handheld inspection tools designed to identify and quantify moisture in wood and common building materials. The premium models bring IGM (Infrared Guided Measurement), pairing a built-in 80 × 60 thermal imaging sensor with the moisture meter so the user can visually guide themselves to the precise spot where moisture may be hiding before taking a reading. The family ranges from a pocket-portable moisture pen to full-featured imaging meters, spanning pin, pinless, and combination sensing along with options such as Bluetooth/METERLiNK connectivity, a built-in 11-group material library, temperature and relative-humidity measurement, and compatibility with FLIR's full line of external moisture probes. Each new model in the FLIR moisture meter family below is its own dedicated product page with condition-matched pricing. Compare the models in the table, then select the page for the specific new model that fits your inspection needs. The MR176 is the line's premium imaging moisture meter. Beyond the shared IGM thermal guidance, it measures temperature and relative humidity through a field-replaceable sensor, offers a “lock image” setting to prevent extreme temperatures from interfering with images, and includes a Progressive Environmental Stability Indicator that signals when relative humidity readings have stabilized for accurate readings in diverse environmental conditions. The models differ primarily in how they sense moisture and in what they add around that core. The MR40 is a two-pin, single-scale moisture pen with a built-in flashlight. The MR55 is a pin meter with Bluetooth and the 11-group material library, while the MR59 is a Bluetooth pinless meter with a ball-tip capacitance sensor that reads up to 100 mm (4 in) below the surface. The MR60 is a pin-and-pinless professional meter with a large-digit display and color bargraph, the material library, and storage for up to 10,000 screenshots and readings. At the top of the line, the MR77 is a 5-in-1 meter combining pinless and pin moisture sensing, a temperature/relative humidity sensor, an IR thermometer, and Bluetooth METERLiNK. The MR160 and MR176 are the IGM imaging meters, each pairing pin and pinless moisture sensing with the 80 × 60 thermal camera; the MR176 additionally carries the field-replaceable temperature/relative humidity sensor. The comparison table below details the moisture ranges, display, storage, connectivity, and power for each model.
