LIBERO CH is a highly versatile multi-use data logger for shipment monitoring as well as monitoring of site and storage conditions. The internal combined temperature and relative humidity sensor comes with a 100% sensor calibration1 . Supporting up to eight temperature alarm zones, 2 humidity thresholds, MKT and duration as alarm criteria – LIBERO CH allows you to create temperature/humidity profiles for individual products. In addition, you have the option to switch the alarming function off and on again if alarming criteria is required. This can be useful in cases where for example a transportation box or storage container has to be cleaned. LIBERO CH can store up to 75’500 measurement values, 37’750 temperature and 37’750 humidity values, and has a battery lifetime of up to 3 years (depending on configuration and usage of the Bluetooth interface). It can be ordered with an optional stainless steel bracket for easy mounting on your equipment. Release products with confidence based on the OK or ALARM status on the display and download the PDF report via the convenient USB interface without any additional software being required. Or use the logger’s Bluetooth interface to download the PDF via an app available for iOS and Android, which you can also use to start or stop the logger without having to remove it from your equipment or consignment.
