                Temperature calibration leader expands Fluke's

EVERETT, WA -- Fluke Corporation, part of the Danaher (NYSE: DHR) family of
companies and a worldwide leader in portable, professional electronic test
tools, today announced that Danaher intends to acquire Lifschultz Industries,
Inc. (NASDAQ: LIFF), including its wholly owned operating subsidiary, Hart

"Hart Scientific has earned a reputation as the premier supplier of temperature
calibration products," said Tom Johnson, precision measurement business unit
manager of Fluke Corporation. "Our own reputation in precision measurement has
been built on excellence in dc and low frequency ac calibration, and we are
committed to maintaining that focus while moving into new growth areas. Adding

"We are happy we found a partner who matched our commitment to the customer, and
who could help us achieve a broader worldwide presence in calibration," said Jim
Triplett, Hart's chief executive officer. "As part of the Fluke organization, we
can grow much faster than we could on our own. We are excited about the
opportunity to provide more service to our existing customers and to expand our
reach to more customers around the world."

"This really is a great fit for both companies," confirms Jim Lico, Fluke
president, "Our customers will be the real winners as we continue to develop
new products and services. This is another step in our efforts at Fluke to
expand our range of test tools solutions for our customers and to grow our
business."

readouts and probes, temperature baths, industrial calibrators and software.

manufacturing companies who rely on precise temperature controls for
manufacturing processes, use the equipment. These industries include
pharmaceuticals, petrochemical and food products.

Lifschultz had revenues of $19 million in their last fiscal year, ending July
31, 2000. Growth was fueled by an expanding market for its products, the
introduction of new products and sales into new geographies. Hart Scientific and
its manufacturing center are based in American Fork, Utah, employing
approximately 100 people. Under the acquisition agreement Hart's operations will
continue to be based in Utah.
