Oxygen is probably the most often monitored parameter in research and different industries, from assessing microbial activity, over determining the leak tightness of packages to oxygen monitoring in natural gas pipelines. With numerous sensor designs, different fiber optic meters and systems for highly parallelized measurements PreSens can deliver an optical oxygen measurement system for almost any application.

pH is an important parameter in research and different industries, from assessing culture conditions, over determining pH in tumor microenvironments to profiling applications in environmental studies. With various pH sensor designs, different fiber optic pH meters, special multi-parameter systems for highly parallelized measurements, or 2D pH imaging PreSens can offer an optical pH measurement solution for a multitude of applications.

CO₂ is an important parameter in research and industries, from assessing culture conditions to measuring pCO₂ in sea water to investigate ocean acidification. With various CO₂ sensor designs and a compact fiber optic CO₂ meter, or 2-dimensional CO₂imaging PreSens can offer an optical CO₂ measurement solution for various applications.

PreSens offers special systems for simultaneous online monitoring of multiple parameters, and highly parallelized measurements in a multitude of samples. These readers can directly be installed inside shaking incubators and allow non-invasive oxygen and pH monitoring in different cultivation vessels, or even optical biomass measurement in shake flasks. Our different multi-parameter systems are designed for culture monitoring applications from mL up to several L scale.
