On Nov. 30, 2010, Klein Tools Inc. acquired a 50 percent equity position in UEi Test Instruments to cement the existing partnership between the two companies.

UEi will continue to offer its growing line of environmental test equipment for the heating, ventilating, air conditioning and refrigerating (HVACR) market while Klein Tools will begin to market its line of electrical test and measurement products to select HVACR customers in January 2011.

“We look forward to expanding our partnership with UEi that started over two years ago and has seen Klein Tools become a leading provider of innovative diagnostic tools for electricians” said Tim Duitsman, vice president of engineering for Klein Tools.

“We are confident this partnership will increase each company’s share of the test and measurement market,” said Michael Kane, president of UEi Test Instruments.
