【ELT SENSOR】CO2 concentration measurement for infection control and prevention!

【ELT SENSOR】CO2 concentration measurement for infection control and prevention!

We quantify the CO2 concentration emitted in human breath to understand the appropriate ventilation methods and duration for indoor spaces. (Equipment available for loan)

Simply by connecting to an outlet, it is easy to monitor indoor CO2 levels. ELT SENSOR is a South Korean manufacturer specializing in sensors, with numerous achievements in various research institutions and the agricultural sector. They develop high-precision, compact modules through their proprietary technology. One CO2 sensor can measure CO2 levels in an area of 100 square meters (such as classrooms or large conference rooms). It can also be installed on walls, preventing loss or falling. It has been proven that when indoor CO2 levels reach 2500 ppm, human performance, including decision-making, significantly deteriorates. Symptoms such as fatigue, drowsiness, headaches, and nausea may occur, and proper ventilation can prevent CO2 levels in offices, conference rooms, stores, and classrooms from exceeding 1500 ppm. *The model shown is a product that displays CO2 levels. Demo units are available for loan.

Purpose of the indoor ventilation status visualization experiment

Purpose of the indoor ventilation status visualization experiment

How can sufficient ventilation be achieved indoors? Verifying the effectiveness of CO2 sensing poles!

This document presents the results of visualizing indoor ventilation conditions. The purpose of this experiment is to find solutions to the question of how sufficient ventilation can be achieved indoors. We measured the changes in CO2 concentration in various parts of the room under ventilation conditions with doors and windows open, assuming the number of people in the classroom was 1/6 or 1/4 of the capacity. We also verified the effectiveness of the CO2 sensing pole in the ventilation state visualization system and published the results. We encourage you to read it. [Contents] ■ Significance of the experiment ■ Standards regarding CO2 concentration ■ Availability of CO2 concentration sensors on the market ■ Experiment details ■ Changes in CO2 concentration indoors with all windows and doors closed (calculated values) *For more details, please refer to the PDF document or feel free to contact us.
