Fluke 345 Power Quality Clamp Meter
Fluke 345 Power Quality Clamp Meter
The Fluke 345 is more than just an electric power meter. It combines the functionalities of a clamp meter, oscilloscope, data logger, and digital power meter into a single convenient device. This makes the Fluke 345 perfect for working with variable frequency motor drives, high-efficiency lighting, and other loads that utilize switching electronics.
The versatile Fluke 345 boasts features like a bright color display for harmonic spectrum analysis, a low-pass filter to eliminate high-frequency noise, and a high EMC immunity design, making it ideal for troubleshooting power quality in switching loads. Its internal memory allows for long-term power quality logging, enabling trend analysis and identification of intermittent issues. Furthermore, the Hall Effect clamp meter design allows for DC current measurement without breaking the circuit.
Fluke 345 Key Features
- Combines the functions of a power analyzer, power quality logger, scope, data logger, and clamp meter in one handy tool
- Measures AC current to 1400 A RMS and DC current to 2000 A without breaking the circuit
- Carries the highest safety rating: 600 V CAT IV rated for use at the service entrance
