MR176 Imaging Moisture Meter

The FLIR MR176 Imaging Moisture Meter Plus with IGM™ is an all-in-one tool equipped with a built-in thermal camera that can show you exactly where to measure moisture. Featuring Infrared Guided Measurement (IGM) technology, the MR176 helps you quickly scan and target moisture issues, visually guiding you to the spot where you can confidently take measurements and analyse readings.

An integrated pinless sensor and an external pin probe provide the flexibility to take either non-intrusive or intrusive measurement. Coupled with a field-replaceable temperature and relative humidity sensor, and automatically calculated environmental readings, the FLIR MR176 imaging moisture meter delivers added convenience and ease of use, producing the right measurements faster.
