CO2 logger sensor NUL-220

CO2 logger sensor NUL-260

This logger sensor is based on an electromechanical reaction between CO2 gas and the sensor.

The result of the electromechanical reaction is voltage, measured by the logger sensor. The measure units are ppm (parts of CO2 per million of air).

Note: The sensor must be calibrated before every use according to the following simple procedure: connect the sensor to the PC through a USB module or a battery module. Wait for about 15 minutes to warm the sensor and press the pushbutton switch on the CO2 logger sensor for 3 seconds. Preferably this calibration should be performed in open space. A bottle adapted to the sensor is supplied.

  • Used in the fields of Chemistry, Physiology, Exercise Science, Biochemistry, Biology, Earth Science, Environmental Science, etc.
  • Includes a CO2 probe, attached to the sensor’s body by a durable rubber coated wire.
  • Includes a glass bottle.
  • The sensor is pre-calibrated at the factory.
  • The sensor offsets to the standard atmospheric CO2 concentration of 380 ppm in open air (assuming stable levels in the Earth’s atmosphere at sea level).
  • Experiment duration: 1 second to 31 days.
