The internal temperature sensor is highly accurate and comes with a 100% sensor calibration.

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 refrigerator has to be cleaned. LIBERO CL can store up to 75’500 temperature 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.

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.
