Product Overview
Multi-use data loggers are advanced, reusable devices designed to provide continuous and highly accurate monitoring of environmental conditions such as temperature and humidity across a wide range of industries. Unlike single-use models, multi-use data loggers like the Polwax Dataloggers can be deployed repeatedly, making them a cost-effective solution for long-term and ongoing monitoring needs in sectors such as pharmaceuticals, food logistics, biotechnology, healthcare, warehousing, and industrial processes. These loggers feature high measurement accuracy (often ±0.4°C for temperature and ±2.5% RH for humidity), robust memory capacity (up to 33,000 data points), and a wide measurement range to ensure reliable performance in diverse and demanding environments.
A key advantage of multi-use data loggers is their flexibility and user-friendly design. They typically offer a large LCD display for real-time data viewing, LED indicators for immediate status feedback, and plug-and-play USB connectivity for easy data retrieval-often without the need for proprietary software. Many models, including those from Polwax, support web-based configuration, allowing users to set up logging intervals, alarm thresholds (up to six programmable alarms), and start modes (manual or automatic) to suit specific monitoring requirements. The replaceable battery design ensures extended operational life, often up to two years, further enhancing cost efficiency and sustainability.
Multi-use data loggers are engineered for durability, with rugged, IP65-rated enclosures that protect against dust and moisture, making them suitable for both stationary and mobile applications. They are standards-compliant, meeting international certifications such as EN12830:2018, CE, and RoHS, which is essential for regulatory compliance in sensitive sectors like pharmaceuticals and food safety. These devices can also be integrated with cloud-based platforms for remote monitoring and advanced analytics, providing real-time alerts and detailed, tamper-proof PDF or CSV reports for audit and compliance purposes.
Typical applications include monitoring vaccine and drug storage and transport in the pharmaceutical industry, ensuring food quality and safety throughout the cold chain, protecting blood products in healthcare, safeguarding sensitive research samples in biotechnology, and optimizing environmental control in warehouses and industrial facilities.

Applications
LOGISTICS
Polwax Cold Chain Data loggers were implemented in cold storage units across multiple warehouse locations. The data loggers continuously monitored temperature and humidity levels, sending data to the cloud for real-time tracking. The system integrated with the logistics provider’s existing warehouse management software.
Biotech
Polwax Cold Chain Dataloggers were placed in the storage units where the biological samples were kept. The dataloggers tracked temperature changes over time, and all data was automatically logged and accessible via a secure cloud platform. Monitor the storage conditions of biological samples.
Fruits Export
The company deployed Polwax Cold Chain Dataloggers inside every refrigerated shipping container. These dataloggers monitored temperature and humidity at multiple points and sent real-time alerts in case of any deviation from the safe range. The data was automatically uploaded to the cloud for access.
