CO2 Monitor

CO2 (Carbon dioxide) monitor

Introduction to CO2 monitors

CO2 monitor measures for the presence of Carbon dioxide (CO2) in room. It also measures ambient temperature and humidity. This monitor is capable of producing accurate readings.

CO2 monitor measurement

Carbon dioxide (CO2) 0 oom to 10,000 ppm
Temperature 0 °C to +70 °C
Humidity from 0 %rH to 100 %rH

CO2 reading quantification:

  • Below 600 ppm: GOOD
  • 600-1200 ppm: NORMAL
  • 1200-1800 ppm: POOR
  • Above 1800 ppm: ALARM

    Introduction to CO2 monitors

    Why you need a carbon dioxide monitor in room

    Carbon dioxide is an odorless and colorless gas. An average human breathes out around 1 kilogram of carbon dioxide in a day. A person working out in gym exhales may be 8-10 times more during the hours. People sitting in closed conference rooms inhale the same breath they exhale. The CO2 gas keep circulating in the room (even with the best venting systems). This leads to yawning, a dizzy feeling, a idleness in personality. A body tends to dry out the living cells and tissues, if enough oxygen is not passed on. Exposure to high level of CO2 for prolonged periods, causes health related problems. Increased levels of CO2 often seen, during winter seasons with a cozy feeling in the bedroom. Overnight the CO2 concentration increases to adverse levels.

    Carbon dioxide is harmful for humans. Modern cities nowadays are over polluted with vehicle smoke, industrial smoke. These gases have more than 40-60% of carbon dioxide along with other pollutants. Moreover, with everyday cutting down of trees is a major cause of increased CO2 levels in the world.

    Hence, we recommend to place a carbon dioxide meter CO2 monitor in the living rooms and bedrooms. Places where you spend most of your time, reading, lying down or at work. Like conference halls, drawing rooms, offices, clinical chambers. On seeing elevated levels of carbon dioxide, people can thereby take necessary actions. Like, allowing fresh air in the room. People using CO2 monitors have dramatic change in their lifestyle. The effects seen with returns of good health and vitality.

    CO2 sensor details

  • Sensor element: NDIR
  • Accuracy: ± 50 ppm + 5% reading value
  • NDIR stands for “Non Dispersive Infra Red”. The sensing element consists of a glass tube. Ambient air passes through one end to the other. A known amount of IR light beam bursts from one side. An IR receptor on the other side capture this light. Particles of CO2 absorb a specific wavelength of the infra red light, leaving the rest. The IR receptor captures all the wavelength. It then subtracts the missing wavelength of light. Concentration of CO2 particles is directly proportional to the amount of missing wavelength. This gives a very accurate reading of CO2 concentration in the atmosphere. The sensor calibrates against inert gas in the tube (where CO2 level is almost 0 ppm).

    CO2 monitor details

  • 600 – 1200 ppm. Indoor air with good air exchange
  • 1200 – 1800 ppm. Yawning, drowsiness, sleepy feeling
  • 1800 – 5000 ppm. Headaches, stuffy and stale air, increased heart rate
  • 5000 ppm. Exposure limit in offices and workplace
  • 40000 ppm and above. Exposure will lead to serious Oxygen deprivation resulting in senselessness / coma
