FAQ: Frequently Asked Questions
Why is nitrogen dioxide (NO₂) monitoring important?
Nitrogen dioxide (NO₂) is a reactive gas belonging to the nitrogen oxides (NOx) family and is mainly associated with combustion processes. It is an important air quality parameter because elevated concentrations can irritate the respiratory system and aggravate conditions such as asthma. Monitoring NO₂ therefore helps assess exposure and identify changes in concentration in occupied environments.
In which environments and applications is NO₂ monitoring useful?
Indoors, NO₂ can originate from combustion sources such as gas cooking and appliances, heating systems, space heaters and certain work activities, or enter from outdoor air, particularly in areas affected by road traffic. Monitoring is therefore useful in buildings, workplaces, environments close to busy roads and other locations where Indoor Air Quality (IAQ) needs to be assessed.
What are the main features of LSI LASTEM nitrogen dioxide sensors?
LSI LASTEM NO₂ sensors use electrochemical cell technology to measure gas concentration in air. The range offers a measuring range of 0–20 ppm, an operating temperature from -20 to 50 °C and an indicative sensor life of 3 years. The sensors are optimised for indoor air quality monitoring and for both portable and fixed applications.
How can LSI LASTEM NO₂ sensors be integrated into a monitoring system?
LSI LASTEM NO₂ sensors can be used for portable measurement surveys or continuous monitoring. Models are available with mV output and MiniDIN connectors for LSI LASTEM data loggers, as well as versions with 4–20 mA and RS485 Modbus that can also be integrated into third-party acquisition systems. NO₂ can also be monitored together with NO, CO, particulate matter and other parameters for a multiparameter assessment of air quality.
