Profiling Microsensors Provide Exact Localised Point Measurements

Oct 04 2017 Read 173 Times

The combination of Presens Precision Sensing’s new and easy to handle Profiling Microsensors (PM) for oxygen or pH with either the automated or manual Micromanipulator and one of its well proofed meters allow safe insertion into samples and precise vertical localisation for point measurements. They also perform stable and vibration-free measurements for extended periods of time. In addition, repeated profiling is possible. Customers measuring in semi-solid substrates, such as sediments, microbial mats or biofilms will profit from the new PreSens products.

The PMs are the sturdiest microsensor version PreSens offers, with a firmer fibre construction and a splash proof metal housing. They have a close fitting fibre guidance and the sensor tip itself is protected by a blunt steel cannula and can be extended with a turning mechanism. The measuring range for oxygen is either 0 - 100% O2, or 0 - 10% O2 and covers a pH range of 5.5 - 8.5. Due to the optical measurement method there is no electrical interference to worry about. The different types of oxygen and pH microsensors allows measurements in smallest sample volumes or inside tissues.
