Medical diagnostic device firm Welch Allyn has acquired all assets of New York-based Scale-Tronix, allowing it to expand services for hospital and physician customers.

Scale-Tronix manufactures medical scales and patient weighing systems, which can be used by hospitals, clinics and extended-care facilities.

Welch Allyn president and CEO Steve Meyer said: "We have added a new diagnostic solution to our physical assessment portfolio that will help clinicians make informed decisions about the care of their patients.

"This transaction further strengthens our position as the market leader in physical assessment products, while expanding our reach further into acute and ambulatory care settings around the world."

Scale-Tronix commenced operations in mid-1970s and produced Model 2001 SlingScale. Later, the company produced different medical scales and patient weighing systems for a variety of healthcare settings.

It has a manufacturing facility in Carol Stream of Illinois, and its employees and contractors will be retained by Welch Allyn to continue development of current products.

Welch Allyn produces physical examination instruments and accessories and EMR-connected vital signs and cardiac monitoring solutions.
