The new location is ETI’s first satellite office, marking a milestone for the company that was founded in 1994.

“We’re excited to establish a local presence in Charlotte and continue to deliver best-in-class calibration services to our customers throughout the Southeast,” says CEO Jonathan Blanchard. “Our North Carolina team will support customers in this area with high-quality onsite calibration services, minimizing the downtime of critical test and measurement equipment.”

Based in Frederick, Maryland, ETI’s primary injection high-current circuit breaker testers are trusted by electrical testing companies worldwide. Customers and partners include Potomac Testing, Schneider Electric, and Protec Equipment Resources. The company specializes in the repair of breaker testers, relay test sets, insulation testers, transformer ratiometers, oil test sets, AC or DC hipot testers, and other electrical testing equipment.

ETI is also dedicated to providing industry-leading customer service that thoroughly answers customer questions in a timely manner.

For Blanchard, a Charlotte office supports ETI’s existing customers in the Southeast as well as the needs of local electrical testing companies and data centers for onsite calibration services.
