The kit also includes a hammer/wall cavity probe combo for additional measurement applications, and a replaceable temperature and relative humidity meter built with the same durability as the MR176 itself.

Gain a competitive advantage with the advanced, affordable inspection tools in the FLIR MR176-KIT6. This kit includes the MR176, a powerful moisture meter with the flexibility to take either intrusive or non-intrusive measurements, and the E6 Pro, the ultimate thermal inspection tool for building, electrical, and mechanical applications. Easy-to-use, rugged, and field-ready, both tools are designed to help you find problems faster and give you that competitive edge. The kit also comes with a hammer/wall cavity probe combo for additional moisture measurement applications.

The FLIR MR265 is a professional pin and pinless moisture meter with thermal imaging designed to show you exactly where to investigate issues related to moisture, air leaks, and insulation voids. Featuring IGM (Infrared Guided Measurement) and MSX (Multi-Spectral Dynamic Imaging enhancement) technology, the MR265 helps you quickly scan and target problem areas, visually guiding you to the spot where you can confidently take measurements, analyze readings, and ensure that problems are fixed. Using FLIR Thermal Studio, you can then create and share professional reports that include findings and proof of repairs – giving your clients peace of mind that mold, rot, or moisture challenges have been resolved.

The MR277 is the first FLIR building inspection system to combine the advantages of Infrared Guided Measurement (IGM) and our patented Multi-Spectral Dynamic Imaging (MSX) with advanced environmental sensors to help you quickly locate, clearly identify, and easily document problems. IGM technology and a laser pointer isolate the area where you can use the integrated pinless moisture sensor for non-invasive readings or external pin probe for invasive measurements. With automatically calculated environmental readings and a field-replaceable humidity/temperature sensor, the MR277 lets you finish the job and minimize downtime. Connect to external devices with METERLiNK and use FLIR Tools to enhance troubleshooting and reports.

The FLIR MR40 is a pocket-portable, rugged 2-pin, single-scale moisture meter with an integrated flashlight for wood and common building materials — ideal for builders, building inspectors, remodelers, moisture remediation technicians, pest control professionals, and residential roofing and flooring contractors. Providing reliable and accurate measurements offered at a highly affordable price point, MR40 is a quick and easy-to-use tool to find and quantify moisture content.

The FLIR MR55 is a pin-based meter with wireless connectivity, which offers the convenience to view readings from a mobile device via the METERLiNK app. Thanks to a built-in library of 11 material groups, users can tune the meter to the appropriate test material to improve measurement accuracy. This library is easy to access on the FLIR.com website by scanning a QR code on the back of the meter with a mobile device.

The FLIR MR59 is a pinless meter with wireless connectivity, which offers the convenience to view live readings from a mobile device via the FLIR METERLINK App. Thanks to the ball-shaped sensor, users can cover a large area in a short time without making a mark; measure into corners and around baseboards easily; and detect problems below the surface.

The FLIR MR60 Moisture Meter Pro is an easy-to-use pin and pinless moisture meter with advanced functionality. An integrated pinless sensor and an external pin probe provide the flexibility to take destructive or non-destructive measurements. Select one of the eleven material groups for pin moisture, or set a reference point for pinless moisture scanning. Then conveniently save screenshots of your measurements as a CSV file with the date, time, and settings.

The FLIR MR77 has everything you need for moisture remediation or HVAC: a pinless moisture sensor and pin probe, a temperature and relative humidity sensor, and an IR thermometer. The meter includes Bluetooth for remote viewing and sharing, as well as METERLiNK technology to wirelessly embed readings into radiometric infrared images on compatible FLIR thermal cameras. Made with field-replaceable sensors, the MR77 is engineered to help you get more done in less time.
