The FLIR DM64 is a True RMS HVAC digital multimeter with integrated temperature measurement. Built for long-term stability and robust performance in field use, it is presented as an all-in-one tool for professionals who install, inspect, and maintain HVAC systems, combining a broad measurement feature set with an easy-to-use, ergonomic design and an on-screen menu system.

The DM64 is intended for HVAC professionals installing, inspecting, and maintaining HVAC systems. Its capabilities map directly to common field tasks: diagnosing complex systems with both high and low voltage measurement, testing flame sensors using the microamps feature, identifying live wires through probe-contact voltage detection, and comparing new readings against stored data to flag deviations from normal operating conditions.

ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, and has served test-and-measurement buyers since 1992.
