PreSens' Featured OEM Components for Monitoring in Microfluidics

Electro-Optical Module EOM-O2-FOM

Electro-Optical Module EOM-O2-FOM

The EOM-O2-FOM is a precise, single channel module for non-invasive O2 measurement. It is compatible with sensor spots, probes, and flow-through cells of type PSt3 (max. measurement range 0 – 100 % O2, limit of detection 0.03 % O2). The small outer dimensions and low power consumption enable the simple integration into custom monitoring and control systems. The device uses RS232, RS485 or USB 2.0 as a digital interface. A serial communication protocol is offered for data exchange between a PC or another host unit and the EOM. Additionally, the EOM has 4 to 20 mA analog output and a Pt100 temperature sensor interface for temperature compensation of the oxygen measurements.

Electro-Optical Module EOM-pH-PHB50

The EOM-pH-PHB50 is a precise, single channel module for non-invasive pH measurement. It is compatible with sensor types HP5 & HP8 (pH 5.5 – 8.5). The small outer dimensions and low power consumption make it very easy to integrate this board in custom monitoring and control systems. EOM-pH-PHB50 uses RS232, RS485 or USB 2.0 as digital interface. A serial communication protocol is offered for data exchange between a PC or another host unit and the EOM. Additionally, the device has 4 to 20 mA analog output and a Pt100 temperature sensor interface for temperature compensation of the pH measurements.

Electro-Optical Module EOM-CO2-FOM

The EOM-CO2-FOM are precise, single channel modules for non-invasive measurement. They are compatible with sensors type CD1 (measurement range from 10 - 250 hPa pCO2). The small outer dimensions and low power consumption enable a simple integration into custom monitoring and control systems. A serial communication protocol is offered for data exchange between a PC or another host unit and the EOM. RS232, RS485 or USB 2.0 is used as a digital interface. Additionally, the EOMs have 4 to 20 mA analog output. A Pt100 temperature sensor interface and the on-board pressure sensor ensure temperature and pressure compensated CO2 measurements.

O2 SensorPlug

The O2 SensorPlug by PreSens is specifically designed for millifluidic and microfluidic applications. With the appropriate chip and port design, SensorPlugs allow for online monitoring of O2 at one or several positions on your microfluidic device. An optical sensor is attached to e.g. a Mini Luer plug, which can easily be integrated in your chip via the corresponding port. A polymer optical fiber with 1 mm diameter connects the plug with an oxygen meter. The sensor is read out non-invasively, so there is no risk of contamination. SensorPlugs are delivered beta irradiated and pre-calibrated and you are ready to start your measurements right away.

pH SensorPlug

The pH SensorPlugs by PreSens enable online pH monitoring in millifluidic and microfluidic applications. With the appropriate chip and port design, the SensorPlugs can be integrated at one or several positions on your microfluidic device. An optical sensor is attached to an e.g. Mini Luer based plug, which can easily be integrated in your chip via the corresponding port. The plug is connected to a pH meter via a polymer optical fiber (1 mm diameter) and the sensor is read out non-invasively, so there is no risk of contamination. SensorPlugs are delivered beta irradiated and pre-calibrated so you can start your measurements right away.

CO2 SensorPlug

This PreSens SensorPlug with optical sensor enables online pCO2 monitoring in millifluidic and microfluidic applications. The CO2 SensorPlug can be integrated at one or several positions on your millifluidic or microfluidic device. The optical CO2 sensor is attached to an e.g. Mini Luer based plug, which can easily be integrated in your chip via the corresponding port. A 1 mm polymer optical fiber connects the plug with a compact CO2 meter. The sensor is read out non-invasively, so there is no risk of contamination. SensorPlugs are delivered beta irradiated and pre-calibrated.

SMA-ST Adapter

This adapter is an accessory for SensorPlugs. As SensorPlugs work with a 1 mm polymer optical fiber with ST connector, the adapter is needed to connect the fiber to the SMA port on the respective meter (EOM).
The SMA-ST Adapter is tested for SensorPlugs. It is not suited to connect other sensors with ST fiber connector (e.g. microsensors) to an optical meter with SMA connector!

Polymer Optical Fiber POF

A polymer optical fiber (POF) is needed to transfer excitation light to the sensor and the sensor response back to the meter. We offer different versions for different meters depending on their optical connector type. A POF enables non-invasive and non-destructive measurements to be made from the outside through the wall of a transparent or slightly colored container. The POF with SMA connector is compatible with meters of the Fibox, OXY-1 SMA, OXY-1 WM,OXY mini and pH mini series, as well as the pCO2 mini. The POF with ST connector is compatible with meters of the Microx 4 and OXY-1 ST series. Different standard lengths are offered, e. g. 2.5 m, and fibers with connectors on one or both ends are available, depending on your adapter or sensor application.
