Fluke PQ400 Electrical Measurement Window

The Fluke PQ400 Electrical Measurement Window enables the connection of three-phase measurement equipment to energized panels, without the need to open the panel door or wear supplemental personal protective equipment (PPE)¹.

Fluke PQ 400 Features

• Reduced risk—Permanently installed voltage and current connections can be accessed without opening the panel door
• Increased efficiency—Quickly connect your logger or analyzer and begin taking measurements faster than ever
• Easy installation—A standard step drill bit and electro-hydraulic hole punch provide the simple means to quickly mount the window in the panel

Compliance without compromise. Safety without sacrifice.

The Fluke PQ400 gives you access to the critical power quality and energy data you need, all while decreasing testing time and helping you to maintain safety.

• Reduce the risk of arc-flash and electrocution, while increasing the safety of your personnel
• Decrease maintenance costs and reduce downtime by making critical power quality and energy measurements without opening the panel door, enabling logging and monitoring at any time—without disrupting operations
• Reduce work permit requirements and processes by reducing the hazards associated with taking measurements on open panels, saving time and effort
• Increase measurement efficiency and reduce the need for arc-flash PPE¹, saving time, increasing efficiency, and increasing operator comfort
