Wireless Ultra-Trace Oxygen Measurement System
OXYBase® UT-Blue
The OXYBase® UT-Blue consists of a robust ultra-trace oxygen probe (limit of detection 0.5 ppmv O2, 0 - 200 ppmv O2 measurement range) with integrated temperature sensor and stainless-steel housing, which is connected to a Bluetooth module. The battery-powered system is controlled wirelessly by smartphone or tablet with the PreSens Wireless Studio app an can be used for wireless gaseous oxygen monitoring in CO2 recovery processes, orbital welding, nitrogen generators or simply whenever measurements of smallest oxygen traces is necessary. The app for wireless oxygen monitoring is available in the Google Play store and Apple App store. The software allows controlling the measurements or calibrating the sensor and offers many additional features. The graphical display of the ongoing measurement gives you quick overview of current oxygen levels. The Bluetooth module together with a data logger, and pressure sensor - for automatic compensation of the oxygen measurements - are integrated in a lightweight water jet protected housing (IP65). Stored measurement data can be downloaded from the instrument to the smartphone / tablet and exported for further analysis.

Applications
Ultra-Trace O2 Monitoring in Industrial Processes
Monitoring gaseous oxygen in sensitive or industrial processes has never been so easy. With the OXYBase® UT-Blue you can control oxygen measurements wirelessly from your smartphone or tablet and detect smallest oxygen traces in your CO2 recovery or inertization processes, in nitrogen generators, or orbital welding.
