The Fluke 437 Series II is designed specifically for the defense and avionics industries. Capable of measuring up to 400 Hz, the Fluke 437 II is a must-have for those working in submarines, aircrafts, and other transport applications.

With the Fluke 437-II power quality analyser, you not only know where Fluke 437 energy loss calculatoryour system is a problem, but you can also see a clear cost related to each area of poor power quality. The Fluke patented algorithm, Unified Power Measurement, measures and quantifies energy losses due to harmonics and unbalance issues. The calculations made by UPM to quantify the cost are computed along with other facility specific information, by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.

Up to four different tariff rates can be entered, with set times that the particular rate applies, which allows you to accurately calculate energy loss in total, even when different tariffs kick in. With this information, you can present a report to your client that will show exactly how much money they are losing as a result of power quality issues, which in turn will help them to decide where to make improvements. Various currencies are available including GBP, EUR & Dollars.
