Stand-alone Fiber Optic Trace Oxygen Meter

Fibox 4 trace

The Fibox 4 trace is a stand-alone oxygen meter designed for easy handheld use. Its robust housing is splash-proof, and the controls were developed to be operated even while working under harsh conditions with heavy gloves on. The oxygen meter can adapt to dry or humid environmental conditions, and is temperature compensated. Additionally, it has automatic compensation for pressure and salinity. Fibox 4 trace can be operated with sensors type PSt3 (detection limit 15 ppb dissolved oxygen, 0 – 100 % oxygen), type PSt6 for the trace oxygen range (detection limit 1 ppb dissolved oxygen, 0 – 5 % oxygen), and also with type PSt9 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 just in one scan. Its sensor management system allows to store data of up to 100 sensors. Fibox 4 trace has 16 GB internal memory which allows prolonged computer-independent operation. It is delivered with the PreSens Datamanagement software allowing data transfer to a PC for further analysis.

Oxygen Transmission Rate & Permeation Measurement

The Fibox 4 trace is the ideal tool for the packaging industry and material research. Easy sensor handling and calibration speed up measuring oxygen ingress and transmission rates in hundreds of containers and packages. Only one scan of the barcode is enough to start precise trace oxygen measurements. In combination with the PSt9 type sensor, which allows measurements down to 0.5 ppm oxygen, even the oxygen transmission rate of high barrier materials for oxygen sensitive applications - like vacuum insulating panels or photovoltaic modules - can be determined.

Food & Beverage Quality Control

Designed as portable, handheld devices the Fibox 4 and Fibox 4 trace can easily be applied for quality control in the food & beverage sector. Together with the versatile PreSens oxygen sensors which can be integrated in pipes, containers or directly held into samples the Fibox 4 and Fibox 4 trace offer complete freedom and multiple options for application to check the quality and shelf-life of your products in different stages of the production and filling process.

Biological & Environmental Research

The Fibox 4 and Fibox 4 trace are idealy suited for field research. With the robust, splash proof housing the devices can be operated even in harsh conditions. The long lasting battery and almost unlimited storage capacity allow for prolonged computer-independent use. Additionally, special energy management settings for long term measurements can be applied. The intuitive user interface and implemented functions like graphical display of the measurements ensure comfortable and comprehensive application without having to connect the device to a PC / notebook. Combined with different types of dipping probes, and non-invasive sensors the compact Fibox 4 and Fibox 4 trace can be applied in any situation where precise oxygen measurement is needed.

Process Industry

The new sensor management system together with the barcode reader ensures a fast work flow while working with a multitude of sensors integrated in different vessels or flow-through systems. Non-invasive measurements with chemical optical sensors can reduce the risk of contaminations and the Fibox 4 and Fibox 4 trace ensure precise oxygen measurements in critical processes. Working with the devices and the respective PC software huge amounts of data can be easily handled while ensuring a maximum of safety, due to the improved data and user management.
