1. Rotronic goes CO2!

2. CO2 Topics: CO2 in general CO2 transmitter CO2 & Temp. transmitter CO2 special transmitter

3. CO2 in general

4. Big topic over the last year, everybody has it.. e.g. Green house effect and environment …

5. CO2 in general

6. Photosynthesis: Chemical recation CO2 + H2O --> CHO + O2 + H2O Carbon dioxide, water  using light and chlorophyll, oxygen and glucose

7. CO2 in general

8. Indoor air quality in offices leads to high or low levels of gases: Since CO 2 is exhaled by people at predictable levels the content of Carbon Dioxide - CO 2 – in air may be a significant indication of air quality. A measure of CO 2 indicates the amount of fresh air supply: 15 cfm = 7.0l/s ventilation rate per occupant corresponds to 1000 ppm CO 2 20 cfm = 9.2l/s ventilation rate per occupant corresponds to 800 ppm CO 2

9. Normal CO 2 Levels The effects of increased CO 2 summarized: normal outdoor level: 350 - 450 ppm acceptable levels: < 600 ppm complaints of stiffness and odors: 600 - 1000 ppm ASHRAE and OSHA standards: 1000 ppm general drowsiness: 1000 - 2500 ppm adverse health effects expected: 2500 - 5000 ppm maximum allowed concentration within a 8 hour working period: 5000 ppm CO2 in general

10. Extreme and Dangerous CO 2 Levels slightly intoxicating, breathing and pulse rate increase, nausea: 30,000 ppm above plus headaches and sight impairment: 50,000 ppm unconscious, further exposure death: 100.000 ppm
