Description

Fluke 1738 Three-Phase Advanced Power Logger

Powerful and highly reliable, the Fluke 1738 is an advanced power logger ideal for use in load studies, energy assessments, harmonic measurements, voltage and current event capturing and all other power quality applications.

The upgraded, advanced version of Fluke's 1736 power logger, the 1738 includes additional functions. The main inclusions are a PQ health (EN50160) analysis function, support for Fluke Connect optional modules and WiFi download of testing data.

When evaluating power quality, the 1738 proves its worth almost immediately. It'll automatically capture and log over 500 power quality parameters, allowing you to gain a detailed snapshot into where you're losing power and improvements can be made. Everything can be captured, including dips, swells and inrush currents alongside time and date-stamped data for easier referencing.

Thanks to an improved and optimised user interface, the 1738 is much easier to set up than other analysers. Quick, guided graphical setup screens will guide you through making connections, with intelligent verification ensuring that everything is connected up right before testing proceeds. A bright, full-colour touch screen makes it easy to switch through modes and interact with testing data as and when needed.

The Fluke 1738 also has the highest safety rating in the industry: CAT IV 600V and CAT III 1000V for use everywhere from service entrances and beyond.

Optional Fluke Premium Care - 1 Year (UK Only)

Accidental damage and repair costs included
Expedited calibration and repair
Annual tool inspection, calibration, and updating
Replacement of damaged accessories (Some limitations apply, see Fluke Terms and Conditions)

Select the Premium Care option in the dropdown box when choosing the model you wish to purchase, only available for users in the UK. Please visit our Blog for more information.
