Profiling Oxygen Microsensor PM-PSt7

The PM-PSt7 is one of the most robust oxygen microsensor PreSens offers – with a firmer fiber construction and a splash-proof metal housing. It is specifically designed for profiling applications and should be used whenever minimal invasive measurements need to be performed in semi-solid samples, e. g. in sediments, microbial mats or biofilms. The PM-PSt7 is compatible with the Microx 4 series oxygen meters and has a measurement range of 0 – 100 % oxygen, with a detection limit of 0.03 % oxygen. Together with the Automated Micromanipulator and the software PreSens Profiling Studio boundary layers and gradients can be followed online, while the sensor is automatically moved inside the sample.
