PreSens offers a range of oxygen meters. Below, we have described some of them, but if you are looking for a specific model that is not listed, feel free to reach out to one of our sales representatives for more information.

The device is controlled wirelessly via a smartphone and the PreSens Wireless Studio app. The software allows users to adjust measurement settings, monitor readings, or calibrate the sensor while offering additional features such as salinity compensation. The graphical display of ongoing measurements enables a quick assessment of oxygen levels. Stored measurement data can be downloaded from the device to a smartphone and exported for further analysis.

Fibox 4 Trace – Standalone Oxygen Meter

Fibox 4 Trace is a standalone oxygen meter designed for easy handheld use. Its robust, splash-proof housing and intuitive controls allow operation even in harsh conditions while wearing heavy gloves. The oxygen meter adapts to dry or humid environments and is temperature-compensated. Additionally, it features automatic compensation for pressure and salinity.

Fibox 4 Trace is compatible with PSt3 sensors (detection limit: 15 ppb dissolved oxygen, 0 – 100% oxygen), PSt6 sensors for trace oxygen measurements (detection limit: 1 ppb dissolved oxygen, 0 – 5% oxygen), and PSt9 sensors for ultra-low oxygen measurements (detection limit: 0.5 ppmv, 0 – 200 ppmv gaseous oxygen). With its integrated barcode reader, the oxygen meter can identify and calibrate a sensor with just a single scan.

OXY-4 SMA (G2) – Multi-Channel Oxygen Meter

This multi-channel oxygen meter is ideal 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% O₂). Each channel in the OXY-4 SMA has separate temperature compensation, ensuring highly accurate measurements in environments with fluctuating temperatures.

The oxygen meter operates with PreSens Measurement Studio 2 software, which enables simultaneous control of multiple devices, allowing for the setup of measurement networks. With numerous features, including additional compensation for pressure and salinity, the OXY-4 SMA is suitable for almost any application.

VisiSens TD

VisiSens TD enables simultaneous 2D imaging of optical O₂, pH, and CO₂ sensor foils within a single setup. Flat sensors for one or multiple analytes are placed on the sample area or in different cavities, and the fluorescent sensor signals are read pixel by pixel with a camera. Fields of view ranging from mm² up to 30 cm × 25 cm are possible.

VisiSens TD provides an overview of your sample area, allowing you to freely select the region of interest for investigating spatial and temporal gradients or simultaneously reading multiple sensor signals. The modular system can be customized according to user requirements.
