Monitoring Applications

Equipment Monitoring for Every Temperature Range

Vaccines remain effective only when stored within the correct temperature range—not just during transport, but also in storage at manufacturing sites, distribution hubs, and healthcare facilities. In refrigerators, freezers, or ultra-low freezers, reliable hardware and software solutions help maintain compliance, ensure temperature visibility, and support full accountability.

FAQs

Common Questions About Vaccine Cold Chain Monitoring

Navigating vaccine logistics requires precision, compliance and reliability. Below are answers to some of the most common questions about how ELPRO’s monitoring solutions support safe, effective vaccine storage and transport.

What makes ELPRO’s solutions ideal for vaccine cold chain monitoring?

ELPRO offers end-to-end temperature monitoring solutions tailored specifically for vaccines—from WHO-prequalified data loggers to real-time cloud software. Our systems provide automated compliance, detailed reporting and flexible monitoring options to ensure vaccine potency throughout storage and transit.

Are ELPRO data loggers WHO prequalified?

Yes, some ELPRO data loggers are WHO prequalified, including the LIBERO CB (PQS E006/022) and LIBERO CS (PQS E006/023). These devices meet rigorous PQS standards and are trusted by global health organizations and NGOs for reliable vaccine monitoring in low-resource settings.

What WHO guidelines apply to vaccine temperature monitoring?

The World Health Organization outlines specific performance, accuracy and durability requirements for vaccine temperature monitoring devices under the Performance, Quality and Safety (PQS) system. Devices must demonstrate reliable performance under field conditions and ensure that vaccines are stored between +2 °C and +8 °C unless otherwise specified. ELPRO’s WHO-prequalified solutions are designed in accordance with these PQS guidelines.

How do I choose the right ELPRO monitoring device for my vaccine cold chain?

Device selection depends on your application: For last-mile vaccine delivery or remote field campaigns, single-use WHO-prequalified loggers like LIBERO CB or CS are ideal. For real-time tracking during global shipments, consider LIBERO Gx. For clinics or storage sites, multi-use loggers with Bluetooth® and elproCLOUD integration offer continuous visibility. ELPRO can help assess your use and recommend the right solution.

Can I monitor vaccine temperatures in real time?

Yes, ELPRO offers real-time monitoring solutions using cellular and Bluetooth® data loggers integrated with elproCLOUD and liberoMANAGER platforms. This allows for automatic alerts, immediate visibility and fast decision-making to protect against temperature excursions during transit.

How do ELPRO systems support compliance and audits?

ELPRO’s software solutions provide 21 CFR Part 11–compliant digital records, automatic reporting and clear audit trails. Whether you use our single-use loggers or install permanent systems, you’ll have easy access to the data and documentation needed for regulatory inspections.

Do ELPRO solutions work in remote or low-infrastructure environments?

Yes. ELPRO’s battery-powered, compact data loggers are easy to deploy anywhere—no specialized training or infrastructure required. WHO-prequalified options like the LIBERO CB and CS are especially well-suited for vaccine campaigns in remote or resource-limited areas.

What support does ELPRO offer for implementation?

ELPRO provides expert consultation, validation support, and ongoing technical assistance to help configure and maintain your monitoring system. Whether for a centralized facility or international distribution network, we tailor our service to your specific needs.

Can I integrate ELPRO data with other systems?

Yes. Both elproCLOUD and liberoMANAGER offer API integrations, making it easy to share environmental monitoring data with ERP, LIMS or other enterprise systems. This ensures smooth data flow and centralized oversight.

Is ELPRO monitoring scalable for large vaccine programs?

Yes, ELPRO offers solutions are modular and scalable—ideal for small clinics, national immunization programs or multi-national pharmaceutical supply chains. From simple indicators to multi-site cloud platforms, our systems grow with your needs.
