  • The electro-optical modules have a small outer diameter and low power consumption and will expand your system’s functionality for non-invasive or minimally invasive optical measurements. Our integration guide guarantees the fast implementation of the devices. As a standard digital interface, they use a RS232 or RS485 communication port. Different communication protocols, including Modbus, are available. Additionally, a 4-wire temperature sensor can be connected for online temperature measurements. Our pH OEM components are designed for use with non-invasive optical pH sensor spots and flow-through cells. The oxygen OEM solutions include transmitters for optical oxygen measurements in normal or trace oxygen range, as well as a microfiber optic EOM for connection of oxygen microsensors. CO2 OEM components can be implemented for non-invasive measurements in the liquid phase. For many years now PreSens also provides optical biomass measurement solutions. If you are interested in a customized biomass monitoring unit, please CONTACT US. The production of the boards according to ISO 9001 and upon specific agreement to EN ISO 13485 AC guarantees certified quality.
