Streamlined Thermal Mapping & In-Depth Data Analysis for Pharmaceutical Warehouses with Bluetooth Temperature Data Sensors

Thermal mapping, also known as temperature mapping, is the practice of deploying multiple thermal mapping sensors across a space like a warehouse to continuously capture temperature data and then analyze the temperature distribution, fluctuation patterns and risk areas in different regions, so as to verify whether the environmental conditions meet certain requirements. The thermal mapping is widely conducted for pharmaceutical warehouses, helping pharmaceutical enterprises and cold chain management teams to identify hot spots and cold spots, guarantee pharmaceutical quality and regulatory compliance. 

Freshliance now provides you BlueTag TH30R, a Bluetooth temperature data sensor designed to simplify the thermal mapping process for pharmaceutical warehouses with streamlined process and in-depth data analysis.

Infinite flexibility and accurate pharmaceutical thermal mapping

BlueTag TH30R delivers accurate data monitoring. The built-in sensor covers -30℃~+70℃ with the high accuracy of ±0.5℃ F.S. and the resolution of 0.1℃; and the optional external probes are available in ranges of -30℃~+70℃/-40℃~+85℃/-90℃~+200℃/-196℃~+200℃. They cover the full expected temperature range of all kinds of pharmaceutical warehouses, including potential excursions.

In thermal mapping, temperature sensors should be strategically deployed across the pharmaceuticals warehouse to ensure comprehensive coverage of the warehouse environment, get the real environmental temperatures and the spatial temperature uniformity across different points. While following standardized approaches such as 9-point mapping, additional sensors should be positioned in areas with a higher risk of temperature fluctuation, including corners, doorways, air supply and return vents, loading zones, and other locations affected by external conditions.

Different from conventional temperature loggers, each BlueTag TH30R Bluetooth temperature data sensor flexibly monitors temperature and humidity with the built-in or external probe for thermal mapping. The external probe cable is 2m long, with customizable lengths available up to 5m, 10m, 15m or even 20m. This enables easy sensor placement and precise data capture at corners, air supply and return vents, etc. And the main device can be easily installed via magnetic suction, wall mounting or folding stand.

Batch configuration & data retrieval via APP

Thermal mapping often involves heavy, tedious device configuration and operation. With Bluetooth connectivity, thermal validation engineers easily run the dedicated APP on their mobile phone to add and configure up to 20 Bluetooth temperature data sensors each time, setting verification name, second-level logging interval (1s~60min configurable), start time, recording duration, and adding specific description for each sensor. Once configured, all the thermal mapping sensors execute the logging schedule as configured and log numerous data points with timestamp accuracy. Powered by a rechargeable lithium battery (1000mAh), each sensor delivers an up to 300 days of continuous operation on a single charge, far exceeding the WHO-recommended 7-day mapping duration for pharmaceutical storage.

At the end of data logging, engineers simply stop the verification and download data via the same Bluetooth connection—no docking stations, no USB adapters.

Reliable data integrity, in-depth data analysis & audit-ready reports to email

After recording, the sensors reliably record data, without any risk of data loss, thanks to onboard memory that safeguards every reading. Upon data access via Bluetooth, the APP automatically counts data points, maximum/minimum/average values and the differences—for each individual sensor as well as across multiple sensors, and intuitively display them in PDF and CSV reports, helping validation teams to quickly identify hot spots and cold spots. The reports can be directly shared via email to designated decision makers or interested parties, ensuring timely access to validation results and complete traceability.

The APP also automatically generates a comparison chart, allowing validation engineers to visualize temperature and humidity trends from multiple sensors on a single interactive interface.

Device calibration

Before delivery, each thermal mapping sensor is individually calibrated and verified against reference standards to guarantee measurement accuracy. Calibration procedures conform to ISO/IEC 17025 requirements and maintain NIST traceability, delivering the documented accuracy and regulatory confidence that pharmaceutical validation demands.

BlueTag TH30R Bluetooth temperature and humidity sensors facilitate pharmaceutical temperature mapping with Bluetooth connection. Paired with the APP, they streamline the entire validation workflow with wireless parameter configuration, cable-free data offloading, and advanced analytical capabilities.
