Fluke 1736/EUS 3 Phase Power Logger

Fluke's 1736 is an advanced power logging system that makes it easy to discover and amend costly power and energy errors.

Designed for measurements over time to spot trends and sudden problems, the Fluke 1736 can log over 500 individual power quality parameters and performs all logging automatically to reduce effort from the user. Every power element can be monitored and logged, including voltage, current, power, harmonics and other power quality values.

The 1736 is ideal for capturing dips, swells and inrush current alongside additional data including the severity of the problem. It'll also show event waveform snapshots and use date and time stamping to ensure you know exactly when and where the problem occurred.

This product is Fluke Connect enabled. This mode allows the logger to wirelessly interface with other Fluke Connect enabled instruments, or with smartphones/tablets (NOT Included) running the Fluke Connect app.
