Bluetooth Temperature Data Logger with Multiple Temperature Ranges for Flexible Freezer Monitoring
Refrigerators and freezers are widely used in everyday homes, supermarket displays, laboratory sample storage, and pharmaceutical drug preservation. They keep food fresh, maintain proper product presentation, preserve sample integrity, and safeguard the potency of medications with controlled temperature and humidity. So we need a reliable temperature data logger to capture microclimate readings inside these units, ideally with remote data access. This avoids frequent door openings and helps maintain stable thermal conditions.
Now BlueTag TH30R Bluetooth temperature data logger from Freshliance is engineered to address the issue with reliable data monitoring, remote data access and smart data analysis, etc.
Flexible monitoring channels
BlueTag TH30R delivers precise data over the range of -30℃~+70℃ and 0~100%RH, and extends the range to -40℃, -90℃ or even -196℃ with two optional external probes. It covers everything from routine refrigeration to ultra-low freezer and cryogenic monitoring.
The buffered temperature probe and flexible ultra thin cable further ensure more accurate pharmaceutical monitoring and other demanding applications.
Wireless data access, smart data analysis & sharing on cloud
Data is automatically monitored as configured settings. Users can come close to the freezers and refrigerators, enable Bluetooth on their phone and then read data via our dedicated APP Tkeeper wirelessly, without opening the door.
The APP automatically summarizes MAX/MIN/AVG temperature and humidity, delivers chart trends and data lists, alarm details, location info, validation certificates, and exportable PDF/CSV reports—turning every monitoring session into clear, compliance-ready insights. Moreover, the reports can be directly emailed to designated accounts and the PDF reports can be electronically signed after device stop, meeting stricter data management and audit requirements.
Most importantly, all data read by one user will be automatically uploaded to cloud and shared with other users, no matter where they are. This ensures efficient collaborative data management, and no critical data missed by every team member.
Be bound with a gateway for real-time monitoring
In addition to standalone operation, BlueTag TH30R Bluetooth temperature data loggers can be seamlessly bound to a Freshliance GAEA-series Bluetooth gateway, transforming local monitoring into a fully automated real-time system.
The BlueTag TH30R integrates data collection, aggregation, analysis, and compliance management into one solution—turning refrigerator and freezer temperature monitoring from simply "reading data" into true data-driven decision-making, delivering reliable data assurance for homes, supermarkets, laboratories, and pharmaceutical cold chain applications.
