Your individual set-up consists of :
OXY-1 SMA
Due to its small outer dimensions OXY-1 SMA can be set up almost anywhere. It is compatible with non-invasive sensors, dipping probes and flow-through cells of type PSt3 (detection limit 15 ppb dissolved oxygen, 0 - 100 % oxygen). OXY-1 SMA has temperature compensation, so most precise measurements in environments with changing temperature can be taken. This USB-powered oxygen meter is operated with the PreSens Measurement Studio 2 software, which enables simultaneous control of several devices, so measurement networks can be set up. With numerous features and additional pressure and salinity compensation, the software makes the OXY-1 SMA suitable for almost any application where precise oxygen measurements are needed.
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-SMA, OXY mini and pH-SMA series, as well as the CO2-SMA series. The POF with ST connector is compatible with meters of the Microx, OXY-ST and CO2-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.
Oxygen Sensor Spot SP-PSt3-NAU
Sensor spots are the most versatile version of non-invasive optical oxygen sensors. The red side of the spot 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 contactless and non-destructively through the transparent vessel wall. The SP-PSt3-NAU has a measurement range of 0 – 100 % oxygen in dissolved or gaseous phase. The oxygen sensitive coating is immobilized on 125 µm flexible transparent polyester foil, which does not stand autoclaving.
