PreSens is developing, manufacturing and distributing optical-chemical sensors and scientific instruments for the measurement of oxygen, pH and temperature for industry and research. PreSens Precision Sensing GmbH was founded in 1997 as a spin off from the University of Regensburg, Germany. The company combines these long-time experiences of different researchers in the fields of electronic engineering and sensor development. Right from the beginning microsensor systems were sold to researchers in the life science area. Already in its first decade of operation PreSens became one of the leading companies in the field of chemical optical sensors - and it still is. Together with its partners it offers full service in Europe, USA and Asia.

PreSens headquarters at the BioPark in Regensburg, Germany

Based on research activities started in the 1980‘s PreSens Precision Sensing GmbH was founded in 1997 as a spin-off from the University of Regensburg, Germany.

The company combines long-time experiences of different researchers in the fields of electronic engineering and sensor development. Right from the beginning, microsensor systems were sold to customers in life sciences. Already in its first decade of operation PreSens became one of the leading companies in the field of chemical optical sensor technology. Together with its partners it offers full service in Europe, America and Asia.

Versatile Optical Sensor Designs for Almost any Application

PreSens sensors come in many different designs, from robust dipping probes with stainless steel fittings, over small sensor spots, to microsensors with a tip size thinner than a hair. They are extremely versatile and can be applied for precision measurements in micro- as well as in macro-scale. Optical sensors can be easily miniaturized and due to their small size they can even beapplied e. g. in small-scale stirred bioreactors, without disturbing the culture environment or liquidflow. Furthermore, these sensors do not require reference cells and do not consume the analyteduring measurement. One of the greatest advantages of optical sensors, however, is the possibility of remote sensing: The sensing component (the actual sensor) and the electro-optical components for sensor read-out (the meter) do not have to be in direct contact. Optical measurements can be performed through transparent or even slightly colored vessel walls and optical windows. While the sensor is attached to the inner surface of a container its signal is recorded from the outside with the respective meter, reducing the risk of contamination to a minimum. Without sampling errors by oxygen ingress or CO2 outgassing can be avoided and completely closed systems can be monitored online.

Fiber Optic Meters, Special Systems & Imaging Solutions for O2, pH & CO2Measurements

As versatile as our optical sensors are the electro-optical components for read-out. Portable meters with long-lasting batteries and immense storage capacity can be used for long-term measurements out in the field as well as for many different indoor applications. The benchtop fiber optic meters have a small footprint, so they can be set up almost anywhere, and are controlled via PC or notebook. Also special mutli-channel, multi-parameter systems for direct installation inside shaking incubators are available, allowing parallel online monitoring in a multitude of samples. 2-dimensional analyte imaging can be performed with a compact handheld fluorescence microscope that is powered via USB. However, the possibilities of optical measurement are not limited to that: PreSens delivers OEM components that can be implemented in customers’ systems for optical measurements in special set-ups. All PreSens fiber optic meters, readers and detector units are delivered with the respective control software. Optical measurements can be controlled, displayed in graphs and followed online.
