56 AIR MONITORING Indoor air quality monitoring and respiratory health
Critical Environment Technologies, a globally renown manufacturer of Indoor Air Quality (IAQ) systems, understands that these are unprecedented times, filled with uncertainty about many things including maintaining a healthy quality of life. As we have learned over the past several months, COVID-19’s primary symptoms are respiratory. Experts estimate that 40% - 70% of the global population are at risk of becoming ill with COVID related respiratory issues like pneumonia. The scale of respiratory recovery ahead of us is extraordinary. Air quality is a key ingredient in respiratory recovery, aiding in effective and efficient treatment critical to the world’s medical and economic recovery.
Poor indoor air quality not only reduces productivity and feelings of wellbeing but can leave occupants vulnerable to worsening existing respiratory conditions or developing new respiratory health issues. The air quality inside buildings is affected by many factors such as dust, spores, smoke, organic compounds, build-ups of gas ad gaseous emissions, humidity levels and poor ventilation.
The only way to know whether the air quality is healthy or potentially harmful is to use an IAQ monitor that can aid in identifying the levels of indoor air contaminants, determining if the fresh air intake to re-circulated air ratio is adequate, improving processes required to guarantee healthier indoor air, providing a log of readings for
constant analysis so modifications can be made appropriately, increasing comfort and productivity and preventing and reducing sickness.
CET has specifically designed the handheld Yesair IAQ Respiratory Health Monitor for detecting air quality levels and collecting data inside office buildings, schools, hospitals, retirement homes, airports, research facilities, shopping malls, etc.
The air quality targets include ozone, formaldehyde, particulates, TVOCs, carbon dioxide, carbon monoxide, temperature and humidity. Understanding the levels of contaminants we are breathing can prevent exasperating, on-going respiratory issues and provide information upon which actions can be taken to keep the air we breathe indoors as healthy as possible.
In recognition of the impact that COVID-19 is having in communities across the world, CET is supporting the global efforts in preventing, detecting and responding to the pandemic by donating a percentage of the sales of the Yesair IAQ Respiratory Health Monitor to COVID-19 related causes.
PM2.5 particulate matter analyser uses world renowned particulate matter sensor

The PM2.5 Particulate Matter Analyzer from ELV Elektronik AG, which is available as a complete kit and as a ready-to-use device, provides highly accurate measurements of particulate matter pollution down to a particle size of PM1.0 – both on mobile devices and on a desktop PC. This is made possible by a state-of-the-art, precise particulate matter sensor with long-term stability from Sensirion, one of the leading experts for environmental sensor solutions.
The concentration of particulate matter is an important aspect of air quality. Particulate matter, referred to as “PM” for short, is a mixture of solid particles and fine droplets suspended in the air that can be inhaled and cause serious health problems. It is the smallest particles from industrial, transport, and household pollution that we need to think about as humans because they can prove to be very harmful to our health. The smallest particles can penetrate deep into our bodies and can cause asthma, allergies, and cardiovascular and respiratory diseases. The frequency and intensity of this harm to our health increases in line with the concentration of particulate matter in the air we breathe. Various devices, such as the ELV PM2.5 Particulate Matter Analyser from ELV Elektronik AG, are available for avoiding exposure to high concentrations of particulate matter or for identifying its sources.
The ELV Particulate Matter Analyser is suitable for both mobile and stationary applications in the field of particulate matter measurement with its high-quality OLED colour graphic display and convenient depiction of the measured values, a LiPo battery that can be recharged using a USB charging port, and the option to record and output the measured values. The device is available in two versions – firstly, as a complete kit for the electronics enthusiast, and, secondly, as a ready-to-use device for the end user.
“Using Sensirion’s MCERTS-certified, highly accurate particulate matter sensor with long-term stability, we can offer our customers a high-quality environmental measuring device that is ideally suited to specialist, multi-purpose measurement in particulate matter thanks to its range of device functions”, says Markus Ulsass, Managing Editor at ELVjournal.
Sensirion’s SPS30 is the first mass-market particulate matter sensor to achieve MCERTS certification and represents a technological breakthrough in optical PM sensors. The measurement principle is based on laser scattering and makes use of Sensirion’s innovative contamination resistance technology. Together with high-quality and long-lasting components, this technology enables precise measurements from the first time that the device is commissioned and throughout its service life of more than ten years. In addition, Sensirion’s advanced algorithms provide superior PM2.5 measurement performance and higher-resolution particle size binning, giving rise to new possibilities for detecting different types of environmental dust and other particles.
“ELV’s PM2.5 Particulate Matter Analyser is an ideal application for our SPS30 particulate matter sensor, as the device is designed to provide high levels of accuracy and reliable functionality,” says Hartmut Welte, Area Sales Manager at Sensirion.

A simple and effective tool for fighting radon contamination
Over ten percent of cases of lung cancer are linked to an excess of exposure to radon, according to a report from the World Health Organisation.
Radon (Rn) is present from a wide variety of natural and man-made sources. This odourless, colourless radioactive gas is the immediate decay product of radium resulting from the
radioactive decay of uranium that takes place naturally in rock and soil. Hence all people are exposed to Rn in varying degrees.
Most Rn in indoor air comes from soil and is proving to be more of a hazard than levels of Rn in the drinking water supply. The level of Rn inside a building is largely determined by its location and whether the ground on which it is located has significant levels of uranium present to create the gas. Once Rn reaches the open air, it will rapidly dissolve to a relatively harmless, low concentration. However, if it rises in to a home or commercial property, it can be trapped and build up to dangerous levels for people inside the building. The radioactive decay will then create alpha particles, which in turn can cause permanent damage to lung tissue.
To combat this danger, Euro-Gas have developed the Radon SS, a unique, high performance phototransistor gas sensor capable of detecting a field range of 0-65,000Bq/m3
levels, with
a standard range of 1750pCi/l Rn. This user-friendly technology can be easily integrated in portable and fixed air quality and gas detection instruments and offers operators complete data for current and average Rn alpha particle concentration.

and
at concentrations ranging from 5 ppm to 5000 ppm with minimal detection limits averaging from 0.4 ppb to 0.5 ppm. These analysers focus on two main application areas, ambient air (AL, <50ppm) and emission/process (EL <500 ppm; EL S < 5,000 ppm) monitoring.
The one channel nCLD AL, EL and EL S feature an external pump, while the two-channel nCLD AL2 and EL2 include an internal pump. The nCLD “Facelift” boxed solutions consist of five, fixed and preconfigured analysers. The nCLD AL (ambient level) and EL S/EL include a standard NO/NOX
measurement, with an optional NO2 two-channel set-up, a standard NO2 add-on, while AL2 and EL2 include, due to the detection. The slightly modified front panel has been
equipped with an additional power-button and a new internal PC. Additionally, all nCLD- models are capable of a remote power down/up and include a failsafe feature.
