Wireless O2 Measurement Device for Product Monitoring


The OXYLogger is a precise, single channel module for wireless oxygen monitoring inside medium- to large-size product containers. It has a sealed steel housing, and is operated wirelessly via Bluetooth and the PreSens Wireless Studio app (Android and IOS compatible). This O2 meter has a long-lasting Li-ion battery, and an integrated temperature sensor for temperature-compensation of the oxygen measurements. Put the device directly inside sealed containers or the product that needs to be monitored, while you control and record the measurements conveniently on a smartphone or tablet. If you want to monitor the oxygen content in your product or packaging, the app-controlled OXYLogger is the smart solution for you!

  • Measurement range of max. 0 - 100 % O2
