But they didn't violate their trademark, there is no use of the name Fluke or their trademark.
"A trademark is a brand name. A trademark or service mark includes any word, name, symbol, device, or any combination, used or intended to be used to identify and distinguish the goods/services of one seller or provider from those of others, and to indicate the source of the goods/services. " http://www.uspto.gov/trademarks/basics/
You could make an argument that the products themselves are look-alikes, or pursue them if they created a similar trademark to cause confusion, but it doesnt seem to me that they obviously acted to violate a trademark.
