For over 50 years, Superior Signal Company has provided industry with quality products at attractive prices. Our offices and primary production facilities are located in Old Bridge New Jersey, just 35 miles south of New York City. Superior Signal specializes in the manufacturing of smoke generating devices and ultrasonic instruments. In the early 1950's the Superior Signal Company originally designed and manufactured military and ship distress signals for government agencies. While these signals were innovative and effective, they were not suitable for civilian purposes. In 1954, the company developed a safe, non-staining smoke containing no explosive materials for civilian applications. Superior® Smoke Generators have been widely used in many applications, including sewer testing, fire training, leak testing building plumbing, ductwork, boilers and furnaces, tanks, piping, and exhaust systems. Superior® Smoke is highly effective for observing air flow patterns, finding sources of odors, evaluating fume/exhaust, and testing smoke control & alarm systems. Other applications include military and law enforcement, special effects, motion pictures and photography, and a variety of hobby applications. In 1991 Superior Signal introduced the AccuTrak® line of Ultrasonic Leak Detectors. These innovative products were developed for plant maintenance applications including compressed gas leaks, vacuum leaks, detection of bearing wear and internal leaks through valves or steam traps as well as HVAC applications. Superior AccuTrak® quickly became a leading brand in the ultrasonic leak detector market. Superior Signal Company LLC continues to expand our business by offering outstanding service and support to our existing markets, developing innovative new and improved products, and creating new applications and markets for our expanding line of products. A family-owned business for nearly 60 years now, we still make almost everything we sell right here in the USA.
