Formed in 1977, Lascar Electronics started life in a garage in Essex, England designing and manufacturing a range of digital panel meters and complementary power supplies. In 1980, with sales showing significant growth, the company moved from Essex to its current location in Whiteparish, England where its headquarters are still located.

In 1994, the company extended its current range of digital displays and power supplies with the introduction of its first EasyLog data logger.

In 1997, the company opened its first direct United States operation in Savannah, Georgia, and in 2002 relocated its facility to Erie, Pennsylvania where it still resides.

In 2010, the company consolidated its manufacturing and procurement departments with the purchase of an office in Kowloon, Hong Kong, from where the company directs its manufacturing and quality facilities.

In 2015, Lascar opened a dedicated global distribution center in Salisbury, England from where its parts are shipped to customers and distributors across the globe.
