Wireless O2 Measurement Device for Wide Range Measurements
OXYLogger WR-CAF
The OXYLogger is a precise, single channel module for wireless oxygen monitoring in closed environments like product containers, or glove boxes as well as in environmental research.It has a splash-proof stainless-steel housing, and is operated wirelessly via the PreSens Wireless Studio app (Android and IOS compatible). This O2 meter has a long-lasting Li-ion battery, and it can be operated for months (at 1 min measurement intervals) without recharging. Its internal data logger stores all measurement data, which can later be downloaded to your smartphone or tablet via the app. The device’s housing components are made from materials that comply with the applicable regulations and standards for direct contact with food (FDA/EU). Put the device directly inside sealed containers or in the environment that needs to be monitored, while you control and record the measurements conveniently on a smartphone or tablet. The app-controlled OXYLogger is the smart solution for you!
