Instrumentation and Monitoring Equipment
We supply a wide range of devices for the monitoring and analysis of outdoor air quality and immissions: analyzers for gases, particulate matter, with type approval...
Increasing air pollution has created an urgent need to measure and monitor air quality on a continuous basis.
The concentration of pollutants in natural resources – especially air, water or soil – that alters their natural composition is known as immission or ambient air quality, which is measured and monitored using fixed stations in accordance with current regulations.
The main air pollutants whose concentration in the air determines air quality come mainly from industry, vehicles, daily activities and natural processes.
Instruments and devices such as gas analyzers or particulate monitors are used to monitor outdoor air quality, as well as multi-gas calibrators and zero air generators.
Gas analysers are monitoring systems that measure a wide range of pollutant gases, such as sulphur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), oxygen (O2), ammonia (NH3) among others.
These gas analysers use methods such as spectroscopy, electrochemical cells, infrared sensors, gas chromatography and laser technology to carry out the measurements.
Particulate matter measurement is fundamental to assessing air quality, as the measurement of fine particulate matter (PM2.5) and coarse particulate matter (PM10) is essential for compliance with environmental regulations.
The data collected by particulate matter monitors helps to understand air pollution levels, assess compliance with environmental standards and regulations, and make informed decisions about air pollution control and mitigation measures.
Ambient air quality monitoring equipment
Ambient air quality is assessed using the Air Quality Index (AQI), which provides a simplified and understandable representation of air quality at a specific location.
In this context, air quality monitoring networks play a crucial role in measuring and monitoring outdoor air quality: fixed measuring stations with appropriate and accurate instrumentation are strategically located to collect real-time data on the levels of air pollutants, mainly gases and particulate matter.
The data obtained is analysed and used to generate reports and early warnings of excessive pollution levels.
The ICA is based on the concentration of key air pollutants such as particulate matter (PM 2.5 and PM 10) and gases such as nitrogen oxides (NOx), sulphur dioxide (SO2), carbon monoxide (CO) and ozone (O3).
At Envira, we are market leaders in the distribution of outdoor air quality monitoring devices and ambient air quality equipment, working for many years with international brands such as Teledyne API, AMA Instruments, Met One Instruments, Palas and AMS Analítica.
