LogTag USRID-16W

WHO Compliant Vaccine Monitoring

WHO Compliant Vaccine Monitoring


  • Pre-Qualified compliant to WHO PQS specification E006/070 Temperature monitoring devices
  • Stores 40 days of temperature recordings data, factory set with a 5 minute logging interval.
  • Display showing temperature and alarm status of up to three alarms.
  • Automatic generation of a PDF, CSV, LTD report without special software.

Data logger with integral USB connector. The LogTag® WHO compliant USRID-16WC and USRID-16WA/B satisfy the growing need for a cost effective and reliable single-use temperature recorder with built-in USB and display. They are ideally suited for vaccine transportation, pharmaceutical transportation as well as in laboratories and medical centres & healthcare.

The display shows alarm status of up to 3 alarms set at WHO requirements. It plugs directly into the computer USB for easy data download.
Upon download, it automatically generates a fully detailed PDF report with the option to download the data using the freely available LogTag® Analyzer software for a more detailed analysis.
