Unisearch Associates was founded in 1980, and has since become a world leader in the development of gas measurement technology based on Tunable Diode Laser Absorption Spectroscopy (TDLAS).
We manufactured and patented our first instrument, the high-sensitivity (sub-ppbv) LUMINOx NO2 monitor, for commercial use four years after our establishment. Several hundred units were sold prior to our divestiture of the technology in 2005, following a change in the company’s focus to optical products and their applications. We are now dedicated to innovating Tunable Diode Laser (TDL) and Differential Optical Absorption Spectroscopy (DOAS) technologies for gas emissions monitoring across a wide range of industries. Applications of these technologies include process control and regulatory measurement.
Our team consists of installation and service experts who ensure that any equipment you’ve purchased from us operates at peak efficiency. We also have a worldwide network of technical sales representatives to respond to your inquiries. Every member of our staff demonstrates mutual respect, professional conduct and a passion for excellence. Their commitment to providing high-precision instruments and quality service has helped us achieve our current position within the industry.
