Temperature and Humidity Data Logger Unit A57BT with Bluetooth (model A57BT)

The Unit A57BT is a compact temperature and humidity data logger designed to record ambient temperature and relative humidity over time and transfer stored measurements wirelessly via Bluetooth. Its portable, battery-powered design enables monitoring in warehouses, laboratories, transport conditions and indoor environments where continuous climate tracking and cold chain verification are required. The device stores measurement history for later review and supports quick downloads through a Bluetooth connection to compatible smartphones or tablets.

Advantages

The Unit A57BT provides reliable environmental monitoring with a small footprint and low power consumption. Bluetooth connectivity allows fast wireless data transfer without physical access to the logger, while onboard memory retains historical readings for trend analysis. The device's simplicity supports straightforward deployment and relocation, and battery operation ensures portability for temporary monitoring during transport or short-term storage.

Suitable for

• Warehouse environmental monitoring
• Laboratory and research facility climate logging
• Cold chain verification during food or pharmaceutical transport
• Indoor climate control and HVAC validation
• Temporary monitoring during storage or inspection

Key specifications

• Measured parameters: ambient temperature and relative humidity
• Data storage: internal memory for recorded measurements
• Connectivity: Bluetooth wireless data transfer to compatible mobile devices
• Power source: battery-operated for portable use
• Form factor: compact, lightweight housing suitable for mounting or placement

How to use

Place the Unit A57BT in the area to be monitored and ensure it is powered with the appropriate battery. Use a compatible smartphone or tablet with the designated mobile application to establish a Bluetooth connection and download recorded data. Configure sampling interval and start or stop logging as required through the app. Retrieve stored measurements periodically for review, analysis or archival; exported data can be used for compliance records or trend evaluation.

Usage recommendations

Locate the logger away from direct heat sources, vents or strong airflow to ensure representative ambient readings. For transport or cold chain monitoring, secure the unit near the goods being monitored and verify Bluetooth connectivity after arrival to confirm successful data transfer. Replace batteries according to usage intensity and back up downloaded data to avoid loss of historical records.
