UNI-T A57 BT data logger

Product detailed description

We offer a 3-year warranty on this product.

The UNI-T A57 BT Bluetooth Temperature and Humidity Datalogger uses a high-precision digital temperature and humidity module and a low-power microprocessor as the 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 recording, time display, sound and light LED alarm, very low temperature recording, etc. It also supports record editing, data viewing and PDF report export via mobile app or PC software. The datalogger meets the requirements of high-precision measurement and long-term recording of temperature and humidity under various conditions, widely used in food processing, cold chain transportation, storage, etc.
