LogTag® USRID-16W WHO Compliant Vaccine Monitoring

LogTag® USRID-16W WHO Compliant Vaccine Monitoring

Single-Use USB Temperature Recorder with Display

The LogTag® USRID-16W range measures and stores 40 days of real time temperature readings over a measurement range of -30 °C to +60 °C, and is pre-qualified for World Health Organisation (WHO) PQS E006 Standards. 




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.


Product Summary

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.
