The company was founded in San Diego, California in 1988 as Advanced Pollution Instrumentation (API) to provide precision gas analyzers for Air Quality Monitoring (AQM) applications. From the beginning, the company continued to develop and expand its range of instruments, the applications they serve, and the geographic location of its customers.
In October 2001, the original company merged with Teledyne Technologies, Inc. to become Teledyne API. To this day Teledyne API continues to operate as an independent business unit within Teledyne Technologies, with all operations (including product development, manufacturing, sales, and customer service) centered at a dedicated, modern facility in San Diego.
Today, Teledyne API offers a broad range of gas analyzers, monitors, and process control instruments. We continue to be a global leader in Ambient Air Quality Monitoring applications, but have also established leadership in Continuous Emissions Monitors for stationary air pollution sources, and in specialized instruments for the measurement and control of ozone gas in a variety of industrial applications. However, our precision gas instruments are also found in many other applications including clean-room monitoring, contamination monitoring, gas purity applications, etc.
In recent times, we have begun to complement our range of gas analysis instruments with a growing range of particulate monitoring instruments for Ambient Air Quality Monitoring applications.
Our products are sold and supported on a global basis through a network of expert partners operating in more than 80 countries. Across the globe, the Teledyne API name is synonymous with high quality products and world-class customer service.
