BALL PROBE MOISTURE METER
WITH BLUETOOTH®
FLIR MR59
™
The MR59 is an aordable pinless meter for professionals
in moisture remediation, pest control, home or building
inspection, and floor installation. It is a high-quality,
reliable, and easy-to-use moisture-detection tool. Wireless
connectivity makes it easy to view readings on a mobile
device from the FLIR Tools® Mobile app when the meter’s
display is out of view. Thanks to the ball-probe sensor, the
user can cover a large area in a short time without making
a mark; measure into corners, over uneven surfaces,
and around baseboards; and detect problems below the
surface. The MR59 is a reliable standalone meter—or a
useful accessory to pair with a FLIR thermal imager.
LOCATE HIDDEN
MOISTURE EFFICIENTLY
Survey large areas quickly and non-destructively
• Easily run the meter over and around objects on the
measuring surface with the ball-probe sensor
• Create a heat map of the affected area and follow
the migration path to a hidden source of moisture
• Identif y potential moisture problems up
to 100 mm (4 in) below the surface
INSPECT ANYWHERE
WITH EASE
Designed to make your job easier and more efficient
• Wirelessly connect the meter to FLIR Tools
Mobile to view readings on a mobile device
• Work in dim lighting with the backlit
display and bright worklight
• Use with the MR04 extension pole to reduce the need
for a ladder, or to optimize ergonomics for ‘high’ and
‘low’ measuring targets (accessory not included)
