The LIBERO CH
The LIBERO CH is a multi-use PDF data logger designed for monitoring temperature and humidity conditions during shipment, site monitoring, and storage. It features a high-accuracy internal temperature and humidity sensor, which is 100% calibrated for precise measurements.
This logger supports up to eight temperature alarm zones and two humidity thresholds, with configurable MKT (Mean Kinetic Temperature) and duration-based alarms. Users can enable or disable alarms as needed, making it adaptable for different monitoring scenarios, such as cleaning storage containers.
The LIBERO CH has a large storage capacity of 75,500 measurements (37,750 for temperature and 37,750 for humidity) and a battery life of up to 2 years. It generates automatic PDF reports via USB and allows wireless data transfer through Bluetooth® Low Energy (BLE) using the LIBERO Cx BLE app (iOS & Android).
