PreSens' Featured OEM Components for Non-Invasive O2 Measurements

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.

Oxygen sensor spots for non-invasive measurements

Oxygen Sensor Spot SP-PSt3-YAU

Sensor spots are the most versatile version of non-invasive optical oxygen sensors. They can be attached to the inner surface of any transparent glass or plastic vessel like e. g. shake and spinner flasks, tubes, Petri dishes or cultivation bags. Oxygen is measured non-invasively and non-destructively through the transparent vessel wall. The SP-PSt3-YAU has a measurement range of 0 – 100 % oxygen in dissolved or gaseous phase. The oxygen sensitive coating is immobilized on a 1 mm glass support, which can be autoclaved (+ 130 °C, 1.5 atm).

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.
