Vernier CO2 Sensor

Description With this sensor, you can easily monitor changes in CO2 levels occurring in respiration of organisms ranging from peas to humans. A 250 mL respiration chamber with probe attachment is included for running controlled experiments with small plants and animals. On the high range, you can explore human respiratory changes in CO2 levels based on exercise. The lower range offers more sensitivity for cellular respiration and photosynthetic metabolism studies. Specification: Response time: 95% of full-scale reading in 120 seconds Warm-up time: 90 seconds Pressure effect: 0.19% of reading/mm of Hg from standard pressure Output signal range: 0-4.0 V Gas sampling mode: diffusion Normal operating temperature range: 25°C (±5°C) Operating humidity range: 5–95% (non-condensing) Storage temperature range: –40 to 65°C Measurement Range: Low range: 0 to 10,000 ppm CO2 High range: 0 to 100,000 ppm CO2 Typical Accuracy (at standard pressure, 1 atm): Low range: 0 to 1,000 ppm: ±100 ppm 1,000 to 10,000 ppm: ±10% of reading High range: 0 to 1,000 ppm: ±200 ppm 1,000 to 100,000 ppm: ±20% of reading Resolution: 0 to 10,000 ppm CO2: 3ppm 0 to 100,000 ppm CO2: 30ppm
