4 Best Power Quality Analyzers 2025 in the United States

The Fluke 1738/EUS Power Logger is a robust device designed for detailed power-quality analysis, especially suited to industrial applications. In terms of measurement parameters, it offers comprehensive data logging for three-phase power systems, which is essential for accurate power quality assessments. The accuracy is reliable, which is critical in identifying power anomalies. This model also boasts a decent sampling rate, enabling precise capture of transient events and disturbances in the power supply.

Data storage and logging capabilities are strong, enabling long-term monitoring and analysis. The user interface and display are designed to be user-friendly, simplifying the process of data collection and analysis even for those without extensive technical knowledge. Connectivity options are likely robust, given Fluke's reputation, aiding in seamless integration with other systems.

Portability is somewhat limited due to its weight of 11.02 pounds, but it is durable, making it suitable for challenging industrial environments. The inclusion of four lithium-ion batteries is a plus, ensuring operations can continue uninterrupted. While the package dimensions indicate a somewhat bulky device, its performance and reliability make it an excellent choice for professionals seeking thorough power quality analysis.

The Fluke 1775 Three-Phase Power Quality Analyzer is designed for industrial applications like energy surveys, load testing, harmonic surveys, and troubleshooting various power quality issues. It automatically measures essential parameters such as voltage, current, frequency, power, dips, swells, and harmonics, making it a comprehensive tool for power quality analysis. The device offers a clear at-a-glance power quality health indicator, which simplifies troubleshooting for users.

It has a robust build with dimensions of 3.15 x 0.79 x 10.24 inches and weighs 9.15 pounds, indicating it's relatively heavy and intended for stationary use rather than portability. The user interface and display allow easy viewing of data, which is crucial for quick assessments. Connectivity features, while not specified, are generally strong in Fluke products, supporting effective data logging and communication.

The corded electric power source suggests that it requires a stable power supply, limiting its use in more mobile scenarios. The lack of battery inclusion further emphasizes its stationary nature. Given its industrial style and the specific applications it's suited for, the Fluke 1775 is ideal for professionals in the power utility sector and those conducting detailed power quality surveys. It excels in providing detailed and accurate power quality assessments, though its bulk and reliance on corded power might be a drawback for users needing portability and flexibility.

The Fluke 1736/EUS, 3-Phase Energy Logger is a robust tool designed for comprehensive energy logging and power quality analysis. Its ability to automatically capture and log key measurements such as voltage, current, power, and harmonics makes it highly versatile for anyone needing detailed insight into their power systems. The Fluke Connect compatibility allows users to view data locally or remotely via a mobile app and desktop software, adding a layer of convenience in accessing and managing data. This feature can be particularly useful for professionals who need to monitor systems without being on-site constantly.

The instrument can be powered directly from the measured circuit, reducing the need for additional power sources and simplifying setup. Additionally, the highest safety rating in the industry (600 V CAT IV/1000 V CAT III) ensures safe usage even at the service entrance and downstream, making it a reliable choice for high-stakes environments. It includes four flexible current probes, enabling the measurement of all three phases and the neutral, which is crucial for accurate and comprehensive data collection.

Weighing just one pound and featuring a compact design, it is also quite portable and easy to carry around. However, the corded electric power source might limit its portability in certain field conditions where an external power source is unavailable. The Fluke 1736/EUS offers a reliable and comprehensive power quality analyzer, with added benefits of safety and remote connectivity.
