The Microx 4 is a completely stand-alone, portable fiber optic oxygen meter. It can be used with non-invasive sensors & probes (1 mm fiber), and oxygen microsensors (200 µm fiber) in different designs. This oxygen meter is compatible with the wide range of sensors type PSt7 (detection limit 15 ppb, 0 – 100 % oxygen). With its integrated barcode reader the Microx 4 can easily recognize and assign calibration data to sensors in just one scan. The implemented sensor management system allows storing data of up to 100 sensors. Microx 4 has 16 GB internal memory which allows prolonged computer-independent operation. It is delivered with the PreSens Datamanager software: sensor, user and measurement data is easily transferred between the PC and the oxygen meter. The data management and easy data export will facilitate and speed up your analysis.

Applications
Environmental & Biological Research
The handheld Microx 4 & Microx 4 trace are ideal tools for field reasearch, and can be applied for gaseous or dissolved oxygen measurements. Combined with different types of dipping probes, or oxygen microsensors they allow e. g. water quality assessment, respiration measurements, or measurements inside tissue. These oxygen meters are applicable wherever precise oxygen measurement is needed. With their splash proof, robust housing the oxygen meters can be used in harsh environments. Special energy settings for long term measurements, the almost unlimited storage capacity or features like graphical display of your measurements allow for prolonged and comfortable computer-independent use.
Medical & Life Science Research
Microx 4 & Microx 4 trace can be used with oxygen microsensors in different designs. These sensors allow for precise on the spot measurement and profiling inside tissue constructs. PreSens oxygen microsensors are already applied in several tissue engineering applications. Implantable microsensors without any additional housing are ideally suited for customized application set-ups, integration in catheters or direct implantation into soft tissue. As the oxygen meters can also be applied with sensor spots, even non-invasive measurements inside cell culture vessels can be performed, without the risk of contamination.
The Ideal Tool for Packaging & Quality Control
Oxygen inside packaging can lead to oxidative deterioration and shorten the shelf life of products. The portable, handheld Microx 4 & Microx 4 trace are ideally suited for quality control in the food & beverage industries, and can be applied in different stages of production. The oxygen sensors in various designs can be integrated in pipes, containers or directly held into samples taken for quality control. Calibration and sensor recognition via barcode scan will speed up the work flow when investigating oxygen ingress in hundreds of containers and packages. Applied with the needle-type oxygen microsensors the oxygen content in small scale headspace packages or non-transparent containers can be determined with the oxygen meters.
Oxygen Measurements in Biofilms & Sediments
Microx 4 & Microx 4 trace can be used with oxygen microsensors in different designs, which allow on the spot measurements. Needle-type oxygen microsensors housed in a syringe needle can be inserted in biofilms or sediments for oxygen profiling. Perform exact online oxygen measurements in different depths of your sample. Combined with micromanipulators the oxygen microsensors can be inserted in µm steps for exact positioning. Robust dissolved oxygen probes are available also, for easy application in sediments in the lab or out in the field.
