FLIR Instruments DM66 Electrical and Field Service – 1 out of 2 models Review

Let’s Talk About FLIR Instruments DM66 Electrical and Field Service – 1 out of 2 models

The FLIR Instruments DM66 Electrical and Field Service – 1 out of 2 models is a digital multimeter designed for commercial electricians, automation field technicians, service personnel, and electronics technicians. Manufactured by FLIR, this multimeter offers a blend of functionality, accuracy, and durability at a reasonable price point. Its key features include True RMS (TRMS) readings, a low impedance (LoZ) mode to eliminate ghost voltages, and the ability to measure frequency, capacitance, diode, and temperature.

My need for a reliable multimeter stemmed from years of troubleshooting electrical systems in demanding environments. I needed a meter that could withstand the rigors of daily use, offer accurate readings in complex circuits, and provide a comprehensive range of functions. I remember one particularly frustrating incident where ghost voltages led me on a wild goose chase, wasting valuable time and resources; I vowed then to find a meter with LoZ capability.

Unboxing the DM66, my initial impression was positive. The meter felt solid and well-built, with a comfortable weight and an intuitive layout. The included accessories, such as the high-quality silicone test leads and alligator clips, added to the sense of value.

I considered the Fluke 117 and the Klein Tools CL800 before settling on the FLIR DM66. The Fluke 117 is a great meter, but pricier, and the Klein CL800, while cheaper, lacked the temperature measurement capabilities I desired. The DM66 seemed to offer the best balance of features and price.

My first impression was one of cautious optimism. While the DM66 seemed promising on paper, I was eager to see how it performed in real-world conditions. The FLIR DM66 didn’t disappoint me from the first moment.

Real-World Testing: Putting FLIR Instruments DM66 Electrical and Field Service – 1 out of 2 models to the Test

First Use Experience

I first tested the FLIR DM66 on a commercial HVAC system, troubleshooting a faulty control circuit. The DM66’s TRMS capability proved invaluable in accurately measuring the non-sinusoidal waveforms produced by variable frequency drives (VFDs). The readings were spot-on, allowing me to quickly identify the source of the problem.

The meter performed admirably even in the damp environment of the HVAC unit. The IP40 rating offered a degree of protection against moisture and dust, giving me confidence in its reliability. Using the FLIR DM66 was very easy.

The only minor issue I encountered during my first use was getting accustomed to the auto-ranging feature, which took a few minutes to master. Other than this, the FLIR DM66 performed perfectly.

Extended Use & Reliability

After several months of continuous use, the FLIR DM66 has proven to be a reliable and durable tool. The meter has survived accidental drops from a ladder, exposure to extreme temperatures, and constant handling in a demanding work environment. The silicone test leads still look new, without any visible wear and tear.

The meter’s housing shows minimal signs of wear, despite regular use. Cleaning the meter is easy, requiring only a quick wipe-down with a damp cloth. The FLIR DM66 easily outperforms cheaper multimeters I’ve used in the past.

Compared to previous multimeters I’ve owned, the FLIR DM66 offers significantly better accuracy, durability, and ease of use. I am confident in the readings I get. I have had zero issues.
