Cold Room Thermal Mapping with Bluetooth Data Loggers
Before a cold room is put into use, it must undergo strict temperature distribution verification. Cold Room Thermal Mapping with Bluetooth Data Loggers, we identify the high-temperature and low-temperature spots in the storage area, determine key temperature monitoring points, and thus ensure the reliability of cold storage preservation.

Our BlueTag TH30R Bluetooth temperature and humidity data logger is ideally suited for cold room thermal mapping. It features simple operation with no need for professional training: press the top button to power on, connect to your smartphone via Bluetooth, and follow the APP’s guidance to complete device setup and data retrieval.

The number and placement of test points for cold room thermal mapping must comply with relevant standards to guarantee accurate and reliable results. According to regulations such as GSP, the test points in each warehouse shall not be less than 9. The Tkeeper APP’s thermal mapping mode supports up to 20 pieces of BlueTag TH30R Bluetooth temperature data loggers simultaneously, fully meeting compliance requirements. With second-level recording interval, it precisely captures subtle environmental changes. It also supports batch configuration and export for quick, efficient operation—saving time and labor costs.
The cold room Bluetooth data loggers can be placed at critical locations including warehouse entrances/exits, air outlets, and shelves, etc., with flexible installation options: magnetic suction, folding stand, hanging, or wall mounting.
A fully charged device can operate continuously for up to one month, satisfying the WHO’s recommendation of 72 hours of non-stop monitoring. After verification, the APP allows one-click export of PDF and CSV reports with automatic data analysis and summary. Reports can be sent directly via email. Additionally, you can view data comparisons across devices to quickly confirm temperature uniformity at all monitoring points.
The cold room thermal mapping with Bluetooth data loggers BlueTag TH30R helps you: verify the uniformity of temperature and humidity distribution; identify potential risk areas; and meet regulatory requirements (such as GMP/GSP) for storage environments.
