Test Gauge & Backflow Supply

Test Gauge® & Backflow Supply was formally known as Test Gauge Industries. The company was purchased in 2000 and moved from Mt. Prospect, IL to Elgin, IL. In 2003 the decision was made to take a calibration company into a full master parts distributor, which then led to Test Gauge® being one of the nation's fastest growing parts supplier.
