The PreSens Measurement Studio 2 has been developed and designed to control several PreSens devices connected to a PC / notebook with one software. Easy data management for sensors, measurement files, and users as well as export of files into .csv and .xslx format can be realized with just a few clicks. The intuitive measurement control eases performing precise oxygen, pH and CO₂ measurements with multiple devices simultaneously.
The software offers many additional features, like compensation of salinity, so most precise measurements can be conducted. You can also group measurement channels so the temperature and (for O₂ & CO₂ devices) pressure inputs from one single device can be shared with the rest of the grouped devices. Build your own measurement network and measure O₂, pH and CO₂ simultaneously, all controlled from one PC.

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.

This multi-channel oxygen meter is ideally suited for benchtop applications. 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). Each channel of OXY-4 SMA has separate temperature compensation, so most precise measurements in environments with changing temperatures can be taken. The oxygen meter is USB-powered and 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-4 SMA applicable in almost any application.

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.

The Vial Adapter is used to attach the POF (polymer optical fiber) to a 20 mL SensorVial (special glass vial with integrated oxygen sensor foil) using a screw. It can be attached to the vial in different heights for measurement in the liquid phase and the headspace and can also be used in a water bath. The POF is available as a separate accessory.

A sensor stripe is integrated in this 20 mL glass vial. The sensor is read out with an optical fiber, which is held in place by the Vial Adapter. The Vial Adapter can be positioned in different heights. The SensorVial SV-PSt3-20mL-NST is autoclavable, and the ideal tool for respiration measurements. Since the sensor stripes are optically isolated with a black layer they are also very well suited for photosynthesis measurements. For stirred applications the SensorVial is also available with a sensor stripe that does not reach all the way to the bottom. Oxygen can be measured simultaneously in liquid and headspace.
