FLIR MRxx Series Moisture Meters
Models FLIR MR40, MR55, MR59, MR60, and MR77
The FLIR MRxx series instruments are compact, very rugged handheld moisture meters. Depending on the type, they measure material moisture with invasive or non-invasive probes. The MR77 combination unit additionally offers temperature measurement, making it an ideal all-round solution for construction work, building inspections, remodeling, moisture remediation, pest control, and roof and floor work in buildings. For example, the instruments can be used to measure wood species as well as soft building and insulating materials.
- MR40: Invasive (electrode pins) moisture measurement for building materials.
- MR55: Invasive (electrode pins) moisture measurement for building materials, 11 material groups; with Bluetooth.
- MR59: Non-invasive moisture measurement with ball probe, depth up to 100 mm (depending on material).
- MR60: Invasive (electrode pins) and non-invasive moisture measurement; with Bluetooth.
- MR77: Complete building inspection system with humidity hygrometer and MSX IR camera. Complete solution with integrated pinless moisture sensor, pin probe, temperature and relative humidity sensor, and IR pyrometer; with Bluetooth.
- Compact, rugged handheld units with long battery or rechargeable battery life.
