Wireless Trace Oxygen Measurement System
OXYBase® TR-Blue
This battery-powered trace oxygen measurement system is controlled by smartphone or tablet via Bluetooth. the control app is available in the Google Play store and Apple App store. OXYBase® TR-Blue is ideally suited for applications in the food & beverage industries, measurements in inertization, nitrogen generators or wherever wireless trace oxygen measurement is needed. The instrument consists of a robust trace range probe (limit of detection 0.001 % O2, max. 0 - 10 % O2) with integrated temperature sensor and stainless-steel housing, which is connected to a Bluetooth module. 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). The device is controlled wirelessly via the PreSens Wireless Studio app. The software allows system control and sensor calibration and offers many additional features like e.g. salinity compensation. The graphical display of the ongoing measurement gives a quick overview of current oxygen levels. Stored measurement data can be downloaded from the device to the smartphone / tablet and exported for further analysis.

Applications
Trace Oxygen Monitoring in Industrial Processes
Many industrial processes are sensitive to oxygen, and continuous checks on the O2 content are mandatory to ensure the safety of products or persons. OXYBase® TR-Blue allows you to conveniently control measurements from your smartphone or tablet and check trace oxygen levels wirelessly in food or beverage production processes, in nitrogen tanks or during inertization.
