Informational Video
The LogTag HAXO-16BT is a compact Bluetooth data logger designed for reliable monitoring of temperature and relative humidity. It is particularly suitable for sensitive goods in storage and during transport—for example, in the pharmaceutical industry, healthcare, laboratories, controlled storage areas, or the cold chain.
Using the LogTag® Link app, you can view current measurements directly on your smartphone and download stored data wirelessly. The app automatically detects compatible loggers nearby and displays the values clearly.
The logger can remain in the shipment, in the storage area, or at the measurement point. This means that packaging does not need to be opened, loggers do not need to be removed, and ongoing processes do not need to be interrupted.
Less effort for reports and documentation
Retrieved data can be automatically transferred to LogTag® Online . There, measurement data, reports, and alarm notifications are securely available and can be easily shared with the team.
By using the appropriate LogTag® Online features, reports and alarm notifications can be generated automatically and sent to the appropriate personnel. This reduces manual steps and supports efficient documentation.
Faster configuration of multiple loggers
Alarm thresholds and settings can be saved in the LogTag® Link app and transferred to multiple loggers with just a few taps. This saves time, ensures consistent settings, and reduces data entry errors.
Compact, rugged, and designed for the cold chain
The HAXO-16BT is slim enough to fit into existing packaging and shipments. At the same time, it is built to be rugged for use in demanding cold chain and logistics environments.
With a storage capacity of up to 16,000 temperature and humidity data pairs, the logger supports extended monitoring periods in a compact solution.
This Bluetooth data logger is particularly suitable for the storage and transport of sensitive goods—for example, in the pharmaceutical industry, the healthcare sector, and laboratories.
Refrigerator Monitoring with the HAXO-16BT and the HOBO Link App
Typical Applications
The HAXO-16BT speeds up shipment inspection because measurement data can be checked and downloaded wirelessly via an app—without having to read each logger individually on a PC.
During temperature and humidity mapping, the loggers remain at the measurement point. This simplifies measurements in hard-to-reach areas and saves time during validations.
When multiple refrigerators or freezers are in use, the app clearly displays nearby loggers. Custom names and alarm notifications help identify critical measurement points more quickly.
