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. Its internal data logger stores all measurement data, which can later be downloaded to your smartphone or tablet via the app. 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!
