The FLIR DM166 Thermal Imaging Multimeter is a must-have tool for commercial electricians, industrial electricians, electronics, and HVAC technicians. Featuring Infrared Guided Measurement (IGM) that’s powered by a built-in 80 x 60 FLIR thermal imager, the DM166 visually guides you to the precise location of potential problems.
The FLIR 166 allows professionals to efficiently test and troubleshoot electrical, electro-mechanical, and heating, ventilation, and cooling (HVAC) systems.
It’s Infrared Guided Measurement (IGM) gives the added benefit of visualising heat and highlighting temperature anomalies on it’s built-in display. Whether facing cluttered wires, complex panels, or clogged condenser coils, IGM guides users without requiring any direct contact with the test site, increasing both speed and user safety.
• Diagnose faults with broad DMM test functions
• Troubleshoot easier with the unique combination of onboard thermal imaging and traditional DMM test functions
• 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
• Remove high-frequency noise that affects 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
The FLIR DM166 includes the essential measurement features you demand from a multimeter including True RMS AC/DC voltage and current, non-contact voltage detection, VFD mode, and more.
The FLIR DM166 is the most affordable multimeter with built-in thermal imaging available to date.
