Oxygen In Air Sensorr

Oxygen In Air Sensor


The Oxygen in Air solid state sensor measures the partial pressure of oxygen (ppO2) and converts it to an oxygen concentration.

This sensor is not suitable for use in liquid, for aquatic applications use the Oxygen sensor.

Measuring Oxygen In Air

The Oxygen In Air Sensor has temperature and barometric pressure compensation which ensures accurate oxygen concentration readings and enables use over a wide environmental range.

Unlike electrochemical sensors, this sensor is non-depleting which gives a maintenance free lifetime of around 5 years. Once exhausted, the sensor can be returned to Data Harvest to have the sensing element replaced (charges apply).

Practical Teaching

The SmartQ Oxygen In Air Sensor an be used to investigate a number of scientific experiments such as:

  • Monitoring human respiration in inhaled and exhaled air
  • Exhaled breath before and after exercise 
  • Air quality 
  • Oxygen changes during photosynthesis and respiration of plants 
  • Consumption of oxygen as a measure of respiratory activity of animals, insects, yeast or germinating seeds 
  • Decomposition of hydrogen peroxide by the enzyme catalyse 
  • Change in oxygen level during combustion 

Warranty & Support

Supplied with 5 year limited warranty with the exception of the sensing element which has a 1 year limited warranty.

Oxygen: 0 to 250,000 ppm
Accuracy
ppO2; 2% full scale 
Temperature; indication only 
Pressure; ±5 mbar 
02%; determined by ppO2 and pressure accuracy 
Resolution
Operating and storage temperature; 0 to 40?C 
Humidity; 0 – 99% Rh (non-condensing) 
Barometric pressure range; 500 – 1200 mbar (50 – 120 kPa) 
Response time This is dependent on air circulation. In a moving current of air a 90% change in output in 30 s is typical. In still air a likely response is between two to five minutes

Other Information

The sensing element is protected by a fibreglass mesh that allows for circulation of gases (air).
It is completely solid state and contains no lead or liquid electrolytes.
Liquid will permanently damage the Oxygen in Air sensor. If the sensor is to be used where there is a risk of condensation position the sensor so that any liquid that does condense will not come into contact with the sensing element.
