This sensor can be used, as it is, to measure the changing CO₂ levels in a room or environment.

The specially designed casing can also form a closed chamber when using standard laboratory beakers and conical flasks. The casing also allows for inserting additional sensors into a chamber such as Temperature and Oxygen.

This sensor has 2 ranges.

Applications
 

Environmental:

• Variances in classroom CO₂ levels

Biology:

• Plant photosynthesis and respiration
• Respiration of small organisms e.g. microbes, maggots
• Measuring human CO₂ production

Chemistry:

• Candle in a Bell Jar (measuring CO₂ emissions)

Supplied with a steel rod, useful for when the Sensor needs to be clamped in a holding device.

The 0 to 10,000 ppm range gives quantitative results.

The 0 to 100,000 ppm range gives qualitative results showing a pattern of change, rather than measurable changes.

The Carbon Dioxide Sensor uses large pulses of current so needs an adequate supply of power. Check full information about power requirements from the user manual (Resources tab).

Note: EasySense Link and Flash Logger users require a 5 V Power Supply (Order No. 5009) to use with this sensor.
