Fluke’s PQ400 Electrical Measurement Window allows the connection of three phase measurement equipment to energized panels, eliminating the need to open the panel door, or wear supplemental personal protective equipment (PPE). The PQ400 provides access to crucial power quality and energy data, all while diminishing testing time and assisting in maintaining user safety.
The Fluke PQ400 is loaded with features functions and benefits:
• Decrease the possibility of arc-flash and electrocution, while improving the safety of employees
• Reduce maintenance costs and diminish downtime by making critical power quality and energy measurements without opening the panel door, enabling logging and monitoring at any time—without disrupting operations
• Lessen work permit requirements and processes by limiting the risks associated with taking measurements on open panels, saving time and effort
• Increase measurement efficiency and lessen the need for arc-flash PPE1, saving time, increasing efficiency and increasing operator comfort
