Nitrogen Dioxide is typically a product of combustion but can also be found in applications using Nitric Acid in laboratories and industrial processing. Safety limits for short-term exposure to NO2 are less than 5ppm requiring a reliable low range detector. The TOC-30 NO2 detector with its low range 0-20ppm high specification performance is ideally suited for reliable NO2 gas detection in safety monitoring applications. Typical applications will include vehicle loading bays, laboratories and chemical processing.
