The FLIR DM90 and DM91 offer the comprehensive features and durable design professionals need to quickly and safely troubleshoot electrical, electronic, and HVAC/R systems. Equipped with LoZ, VFD Mode, µA current measurement capability and more, the DM90/DM91 multimeters give you trusted results for the most accurate diagnosis of electrical problems. The DM91 is also enhanced with Bluetooth® technology, so you can connect via METERLiNK® to FLIR infrared cameras, or to mobile devices running FLIR ToolsTM or the FLIR InSiteTM workflow management system.
FLIR DM90/DM91™TRMS Multimeter with Type K Temperature
TRUSTED, ACCURATE READINGS
Diagnose complex systems with True RMS, LoZ, VFD, and high- and low-voltage measurement capabilities. You can also assess temperatures up to 400°C (752°F) with the supplied Type K thermocouple, or take non-contact AC voltage readings with the built-in detector.
FAST, EFFICIENT WORK
The DM90/DM91 are designed and built to make your job faster and easier. Work longer without interruption, thanks to powerful LED worklights and flexible battery options. Plus, the DM91 offers a datalogging mode with onboard storage of up to 40,000 measurements, so you can document intermittent trends.
STREAMLINED REPORTING AND SHARING
The DM91 uniquely features Bluetooth METERLiNK® so you can send readings to FLIR ToolTM or to the FLIR InSiteTM workflow management app, embed the data in FLIR thermal camera images, or instantly share with clients.
