We are dedicated to the development of new analytical instruments for atmospheric and environmental measurements. While our specialization has always been in miniaturized instruments for measurements of ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), mercury (Hg), and numerous other chemical species in air. Our goal has always been to use sound science and innovative technology to provide our customers with cutting-edge instrumentation. All the instruments we manufacture utilize absorbance-based monitoring techniques to measure and characterize various air pollutants with high precision and accuracy.
