Introducing the Fluke PQ400 Electrical Measurement Window— the safer, easier way to make three-phase power quality measurements.
The Fluke PQ400 Electrical Measurement Window is a permanently installed interface that allows you to make three phase measurement connections on energized panels, without opening the panel door. Once installed, the PQ400 Electrical Measurement Window gives you access to critical power quality and energy data while decreasing testing time and helping you to maintain safety.
Use the PQ400 Electrical Measurement Window to reduce the risk of arc flash and electrocution when making power quality and energy measurements, increasing the safety of your personnel and reducing the need for supplemental personal protective equipment. With permanently connected voltage and current sensors located inside the electrical panel you can make power quality and energy measurements using the external access points all without opening the panel door. Three phase voltage, current, neutral and ground connects are designed to cover most measurement scenarios, and with full 360-degree rotation you can install the PQ400 window in whichever orientation you choose.
