FLIR DM284/DM285
Industrial Imaging Multimeters with IGM™

The FLIR DM284/DM285 combine thermal imaging with a rich set of digital multimeter features in one convenient diagnostic tool. Infrared Guided Measurement (IGM) technology – powered by the built-in FLIR thermal imager – helps pinpoint the exact location of electrical issues, so you can troubleshoot them fast. The DM285 also helps streamline inspections by connecting wirelessly to FLIR Tools or the new FLIR InSiteTM workflow management app.



Scan your target and spot electrical issues quickly and efficiently. The DM284/DM285 have a 160 x 120 resolution infrared detector that guides you straight to the problem, visualizes the heat generated by electrical faults, and accurately measures the temperature.




Featuring 18 measurement functions including True RMS, LoZ, and NCV, you can verify potential issues with trusted readings every time – even for the most complex measurements. The DM284/DM285 also includes a thermocouple input and allows you to view thermal and electrical measurements simultaneously.



The DM285 uniquely features Bluetooth METERLiNK® so you can send readings to FLIR Tool or to the FLIR InSite workflow management app, embed the data in FLIR thermal camera images, or instantly share with clients. DM285 is ideal for both benchtop electronics or in the field.
