Description
This product comes with a 3-year warranty.
The UNI-T A57 BT Bluetooth data logger for temperature and humidity uses a high-precision digital temperature and humidity module and a low-power microprocessor as a sensor. It is equipped with an internal temperature sensor and measures temperature and humidity via external temperature probes or temperature-humidity probes. It features high accuracy, large memory capacity, automatic logging, time display, LED alarm with sound and light, ultra-low temperature logging, etc. At the same time, it supports log editing, data viewing and PDF report export via the mobile app or PC software. The data logger meets the requirements for high-precision measurement and long-term recording of temperature and humidity under various conditions and is widely used in food processing, cold chain transport, storage, etc. ±3 °C
