ESPEC - Leading Manufacturer of Accelerated Reliability Test Equipment

You are here

World’s Largest Manufacturer of Environmental Testing Technologies

As manufacturing and design technology have made significant advances over the years, the traditional testing regimes have not reflected an enhanced ability to reveal designed in and production induced failure modes that result in product warranty spikes or worse, product recalls. ESPEC’s Combined Environment Accelerated Testing methodology – HALT and HASS have been providing that enhanced ability for product reliability and quality improvements for more than 20 years. They have been one of the leading manufacturers of accelerated reliability test equipment worldwide since pioneering the technology in the early 1990s. Its patented HALT (Highly Accelerated Life Test) and HASS (Highly Accelerated Stress Screen) chamber systems are recognized as one of the fastest and most effective disciplines for design reliability testing and production screening for electronics and electro-mechanical equipment. ESPEC is the knowledge leader in accelerated stress testing methods with over 4,500 HALT/HASS tests conducted in ESPEC's lab facilities and worldwide installations of over 1500 systems in 33 countries in such diverse industries such as Aerospace, Consumer Electronics, Enterprise Systems, Medical, Sustainable Energy and Telecommunications.

In 2015, Qualmark became part of the ESPEC Group of companies as a wholly-owned subsidiary of ESPEC Corporation, headquartered in Osaka, Japan.  ESPEC North America has been a part of this group since 1989. Since the addition of Qualmark to the group, the two companies have taken a collaborative approach to delivering the best environmental and accelerated test systems to the marketplace.  The merger of the companies is a natural evolution of this close working relationship.  The Qualmark brand will be offered as a product line of ESPEC North America, Inc.  Primary manufacturing activities for the Qualmark product line will remain in Denver to assure continuity of supply. 

As of January 1, 2018, ESPEC North America Inc and Qualmark entered in to a complete company merger, following the combination of our respective Sales groups on August 1, 2017.  As with the combining of our Sales forces, this action further strengthens support for both customer bases, for our respective test chamber products, and grows our overall product and service portfolio to be the largest in the electronics and environmental testing industries worldwide. 

ESPEC North America, Inc. is part of the ESPEC Group, which includes:
