Photosynthesis produces oxygen and therefore, plant scientists often need to measure the rate of oxygen evolution. Traditional methods of oxygen measurement require extensive maintenance and the methods are prone to electrical interference. PyroScience optical sensors are a reliable alternative to this.

Our sensor portfolio enables measurement of photosynthesis rates of e.g. enclosed sediment, soil, biofilm, plant, animal, algae, plankton, fish, cell or microbial sample in a closed chamber (air-tight), which is temperature controlled (water jacket or water bath for constant temperature).

Measurement of photosynthesis rates can be performed by using our ready-to-use sensor vials.


With our fiber sensors it is possible to measure oxygen at high spatial resolution with fast response times.
