No more hidden problems and expensive downtime - with the Fluke 435 II power analyser, you can see exactly what's happening inside your essential electrical systems and take corrective action long before problems become serious issues.
Suitable for use with both three-phase and single-phase systems, the Fluke 435 II provides users with a comprehensive suite of power measurement functions at the press of a button, plus a dedicated energy loss monetisation calculator to make sure your systems are running at optimal efficiency.
The Fluke 435 II captures absolutely every aspect of your system to help you find the root of the problem. It can capture voltage, current and frequency, dips and swells, harmonics, power and energy, unbalance, inrush, event waveforms, flicker and transients and much more.
With the built-in energy loss calculator, it's possible to put a real value against how well your systems are running. The calculator uses active and reactive power measurements, unbalance and harmonic power measurements to calculate and display real system energy loss in several local currencies.
These are just a few of the features of the Fluke 435 II; this model is packed full of additional functions including four inputs for use with Fluke flexible current probes, PowerWave data capturing with fast RMS data and much more.
These are either not included with the product or are replacements for items included as standard. Please call us if you're interested in ordering any of these.
These specifications apply to all models in the Fluke 430-II series - 434 II, 435 II and 437 II - unless otherwise specified.
