True RMS DMM Includes Temperature Measurement

FLIR Systems’ DM64 HVAC True Root Mean Square (TRMS) digital multimeter (DMM) with temperature measurement capability is designed for those who install, inspect, and maintain HVAC/R systems. It is quite useful for diagnosing complex electrical systems, testing flame sensors, and measuring temperatures.


The DMM offers both non-contact and probe voltage detection, accurately measures high- and low-voltage, and measures temperatures up to +752°F (+400°C) with the included Type-K thermocouple. It has several measurement modes, including low impedance (LoZ), Relative Zero, and Variable-Frequency Drive (low-pass filter).
