For Wireless Oxygen Measurements in Powdery Media
OXYLogger WR-PX
The OXYLogger WR-PX is a precise, single channel module for wireless oxygen monitoring. It is specially designed for measurements in powerdery media, like e.g. milk powder. The device’s housing components are made from materials that comply with the applicable regulations and standards for direct contact with food (FDA/EU). It is operated wirelessly via the PreSens Wireless Studio app (Android and IOS compatible). OXYLogger WR-PX has a long-lasting Li-ion battery, and an integrated temperature sensor for temperature-compensation of the oxygen measurements. The device can be operated for months without recharging (at 1 min measurement intervals). Its internal data logger stores up to 400,000 data points, and all measurement data can later be downloaded to your smartphone or tablet via the app. Put the device directly inside sealed containers and monitor your product during transport or check packaging safety. With OXYLogger WR-PX you have the tool to control and record the measurements conveniently on a smartphone or tablet.
