Device Introduction
- iMeter 8 is CET’s Advanced PQ Analyzer designed for the compliance monitoring market as it offers un-surpassed functionality by combining Class 0.2S accuracy and advanced PQ features in a 192x192x182.4mm housing with a High-Resolution, Color Dot-Matrix LCD display. The iMeter 8 complies with such standards as IEC62053-22 Class 0.2S, IEC61000-4-30 Ed. 3.1 Class A, IEC61000-4-15, IEC61000-4-7, EN50160, IEEE Std 519-2022 as well as IEC61850 for Substation Automation.
- Further, it offers a large logging capacity with 8GB of on-board memory, extensive I/O, multiple Time Sync. methods, 2x100BaseT Ethernet and 2xRS-485 ports. In addition, it optionally provides 2xAO and 2xAI for different applications. These features likely make the iMeter 8 one of the most advanced PQ Analyzer for an intelligent Power Quality Monitoring System.
