The sensor is designed and optimised to measure carbon dioxide levels found in the air around photosynthesising plants and small, respiring animals and includes two ranges 0 to 10,000 ppm and 0 to 100,000 ppm.
All our sensors are supplied with 5 years warranty and lifetime support.
The unique disc shape lets the sensor become the lid for respiration chambers or placed on a desk without the need for clamps and stands. The holes in the casing allow sensors such as Temperature and electrodes e.g. Oxygen, pH, or Conductivity, to be used at the same time or to add materials to the beaker during the course of an experiment.
The Carbon Dioxide Sensor can be used to investigate a number of scientific experiments such as:

The sensor uses absorbance of infrared energy by CO2 to measure levels (the more infrared light is absorbed the greater the concentration of carbon dioxide). This sensor is for measuring gases – not liquid CO2 concentrations. Liquid will permanently damage the Carbon Dioxide sensor. If the sensor is to be used in an environment where there is a risk of condensation e.g. with a plant in a sealed environment, the sensor should be positioned so that any liquid does not come into contact with the sensing element e.g. use the steel rod to clamp the sensor above the plant. The Carbon Dioxide sensor updates its reading every 0.25 of a second (250 milliseconds). The fastest speed that data can be captured is 50 Hz (20 ms). The yield from some chemical reactions may overwhelm the sensor i.e. produce more than 100,000 ppm. This sensor uses large pulses of current so needs an adequate supply of power. See the product manual for power requirement information. Normally the data logger is able to supply sufficient power, but if the sensor is to be operated for more than 8 hours on a battery powered logger, it may necessary to connect a 5 V mains adapter (Product No. 5009) to the power socket on the Carbon Dioxide sensor.
