Optical oxygen sensors can stand high pressures and are therefore ideally suited for deep sea research. Combined with electro-optical modules, that have a small footprint and can easily be integrated in fittings that stand high pressure oxygen measurements at depths of several thousand meters can be performed.
PreSens non-invasive optical sensors are the ideal tool for respiration measurements. From tiny invertebrates to large aquatic organisms, our O2 and pH sensors can be integrated in most different respirometry chambers.
Some research requires customized measurement set-ups. Due to their small outer dimensions an electro-optical module (EOM) and non-invasive sensor spots can be used to monitor oxygen in closed ecosystems (even in space). The components can be integrated in monitoring units where online oxygen measurements can be combined with other data.
Our oxygen dipping probes with stainless steel fitting are ideal tools for fast assessments in water quality analysis. Combined with portable oxygen meters that are splash-proof and easy to handle, they can be applied even in harsh environments.
PreSens offers several sensor solutions for measurements in biofilms and sediments from micro- to macro-scale: Profiling Microsensors together with our micromanipulator systems are the tools for accurate microprofiling. 2-dimensional assessment of gradient development in flume chambers or sediment cores is possible with the VisiSensTM imaging systems.
Sensor spots for O2, pH or CO2 meausurement can be integrated in transparent vessels and read out non-invasively via polymer optical fiber. By integrating different sensor spots all parameters can be assessed simultanously in one sample.
Our sensor systems measure non-invasive or minimally invasive, which is of great advantage when working with living samples. Microsensors with a sensor tip thinner than a hair can be inserted into tissue or mounted inside catheters for high resolution measurements. Furthermore, sensor foils can be placed directly on the sample surface or a sample cross section and analyte distributions can be determined 2-dimensionally over time.
PreSens non-invasive optical sensors are the ideal tool for respiration measurements. From tiny invertebrates to large aquatic organisms, our O2 and pH sensors can be integrated in most different respirometry chambers.
Robust probes with stainless steel fittings can be applied for long-term monitoring in environmental studies. Portable, splash-proof devices with long-lasting batteries and immense storage capacity allow for prolonged computer-independent work out in the field. 2-dimensional assessment of gradient development or analysis of root soil interactions is possible with the VisiSens™ imaging systems.
