IMAGING TRMS MULTIMETER
TM
FLIR DM166
The FLIR DM166 is the most aordable multimeter with
built-in thermal imaging – a must-have tool for commercial
electricians, automation, electronics, and HVAC technicians.
Featuring Infrared Guided Measurement (IGM™) powered
by an 80 x 60 FLIR thermal imager, the DM166 visually
guides you to the precise location of temperature
anomalies and potential problems faster, more safely, and
eciently. The feature-packed multimeter is an ideal tool
for troubleshooting and diagnosing complex issues in both
high-voltage and low-voltage applications.

TROUBLESHOOT FASTER
One tool gets the job done
• Quickly scan for overheating
components with IGM
• Diagnose faults with broad DMM test functions
• Troubleshoot easier with the unique
combination of onboard thermal imaging
and traditional DMM test functions
WORK SAFER
Identify energized and potentially
faulty equipment from a safe distance
• Safely check for live connections using
non-contact temperature measurement
• Carefully measure voltage with integrated
non-contact voltage detection
• Work with peace of mind knowing your meter
has a CAT III- 600V, CAT IV-300V safety rating
DIAGNOSE PROBLEMS
MORE EFFICIENTLY
Rich feature set covers both high-voltage
and low-voltage applications
• Reliably take 600 V AC/DC voltage
measurements and 10 A AC/
DC current measurements
• Remove high-frequency noise that af fects
readings with the Variable Frequency
Drive (VFD) measurement function
• Precisely measure resistance up
to 60 MΩ, frequency up to 50 KHz,
and capacitance up to 10,000 µF
