The FLIR DM90 / DM91 TRMS multimeter allows you to troubleshoot and repair a wide range of electrical and electronic systems. It includes all the standard measurements: voltage, current, frequency, resistance, continuity, diode, capacitance, and temperature. It is ideal for electricians, service technicians, and HVAC professionals.

It features VFD Mode to filter variable frequency drive signals, providing accurate voltage and frequency measurements during maintenance and troubleshooting. The LoZ Mode eliminates ghost voltage readings associated with long-run applications. It also has uA current measurement capability and Smart/Classic Diode modes.

To maintain superior accuracy the DM90 / DM91 uses True RMS; it converts AC signals into DC signals of equivalent value to stabilize the AC readings, compensating for the natural changes in alternating current throughout the wave period. For convenience it features min and max averaging, peak min/max, hold, auto hold, and auto power off with disable along with a variety of customizable menu settings. In order to improve visibility and ease of use the DM90 / DM91 includes powerful built-in LED work lights, eliminating the need for a separate light source.

The DM91 features Bluetooth connectivity and on board storage, and is available with a NIST certificate.
