With real-time CO2 concentration monitoring

You can lower your risk of corona infection!

● Real-time monitoring of CO2 concentration is the Most powerful and affordable way to prevent COVID-19 infection worldwide.

● Build an environment that prevents Corona 2 with Radionode's NDIR-type CO52 monitoring product, UA2-CO19!

In April 2021, researchers at the Institute for Collaborating in Environmental Sciences (CIRES) and the University of Colorado Boulder published* the Most powerful and affordable way to manage your risk of contracting COVID-4.

The researchers first checked the accuracy of the CO2 detector, and observed how infected and non-infected people breathe (how viruses and CO2 were exhaled), while also observing a mathematical “box model of how viruses and CO2 were accumulated/removed by ventilation” in indoor spaces. ” was created.

Calculations with this Box model can reveal the “relative” risk of being infected with COVID-19 in each indoor space, a study has found that triples the risk of transmission if the level of CO2 in the indoor environment triples.

In other words, a powerful and inexpensive way to manage the level of risk of contracting COVID-19 is to monitor indoor carbon dioxide (CO2) levels. is needed,' he announced.

There is another announcement** that real-time CO2 concentration monitoring is effective in preventing COVID-19 infection. In June of last year, the Research Group of the University of Bari in Italy and the Environmental Medicine Society jointly announced the results of a study on monitoring activities inside an educational building. Real-time CO6 concentration was selected as a proxy for the risk of transmission of COVID-19 and the study was conducted.

A non-dispersive infrared (NDIR) type CO2 sensor was used to study the relationship between real-time CO2 concentration and the risk of COVID-19 outbreak. It turned out to be helpful.

How about your CO2 meter? Can you trust the accuracy?

Radionode UA52-CO2mounted on carbon dioxide The sensor is cost-effective NDIR optical sensor no see. When carbon dioxide is exposed to infrared light, it measures the concentration of carbon dioxide using the principle of absorbing a specific band of infrared light, so the sensor accuracy is high. In addition, since it is optical, it has a much longer lifespan compared to electrochemical sensors.

Radionode not only measures sensors but also software to manage data. Just as iPhone and iOS are optimized for each other, the Cloud Serivce-based 'Radionode365' If you use the sensor data monitoring software, you can store the measured values ​​and use the reference line on the graph to easily determine when ventilation is required. 

Now you can monitor carbon dioxide in real time with a sensor you can trust. 

We can prevent COVID-19 and create a healthy time together.
