GAS—1060
Direct Nitrogen Dioxide Analyzer
US EPA Designated Equivalent Method
Version 3.0

Met One Instruments is now part of the Acoem Group. The Met One
range of gas analyzers was originally developed by Acoem under
the brand name Ecotech Serinus®.
For the purposes of expediting the availability of Met One gas
analyzers to Met One customers around the world; Met One
Instruments have chosen to use the original Ecotech Serinus®
operating manual.
Although the name of the Met One instrument is dierent, the
analyzer itself has remained unchanged and meets the strictest
quality and performance requirements expected of Met One
equipment. All the information presented in this manual is current,
including analyzer specications and operating principles.
Met One will update this manual to reflect the new branding
convention in due course.

1. Introduction
1.1 Description
The Serinus 60 Nitrogen Dioxide Analyser (NO2) utilizes cavity attenuated phase shift spectroscopy
detection to perform continuous analysis of nitrogen dioxide.
The Serinus 60 can measure to a sensitivity of 20 ppt with a range of 0-1 ppm. The measurement of
this gas is performed with the following main sub-components:
Particulate filters
Sample dryer
Measurement cell (temperature controlled)
Light source (Blue LED) and Photo Detector
Interface PCA
A microprocessor programmed with Serinus firmware monitors the detector response and many
other parameters. The concentrations are automatically corrected for gas temperature and pressure
changes and when using gravimetric units (e.g. μg/m³) is referenced to 0°C, 20°C or 25°C at 1
atmosphere. This allows the Serinus 60 to provide readings in the relevant units for your
requirements. This section will describe the specifications of the instrument as well as the main
components and techniques used to obtain stable gas concentration readings.
