Sentinel™ Monitoring System Can Help Health Care Providers Meet COVID-19 Vaccine Ultra-Cold Storage Requirements

Sensaphone Sentinel Monitoring System

The Sentinel system delivers 24/7 remote monitoring of temperatures inside medical refrigerators and freezers from -85 °C to 76 °C (-109 °F to 168 °F).

Proper vaccine handling and storing practices will play a vital role in the distribution of COVID-19 vaccines. The Sentinel™ monitoring system from Sensaphone can help health care professionals maintain strict ultra-cold storage temperature requirements. When paired with Sensaphone’s Ultra Low Temperature Sensor, the Sentinel system can monitor temperatures as low as -85 °C / -109 °F. The system is ideal for hospitals, labs, pharmacies and clinics as they prepare to provide millions of vaccine doses.

The Sentinel system delivers 24/7 remote monitoring of temperatures inside medical refrigerators and freezers from -85 °C to 76 °C (-109 °F to 168 °F). When the system detects the temperature has moved out of the desired range, it sends an alert via phone call, text or email to the designated contacts.

In addition to temperature monitoring, each unit can monitor up to 12 different environmental and equipment status conditions. Users can also monitor the freezer’s alarm panel for power outages.

The Sentinel system’s enhanced data logging capabilities allow users to print, graph or export reports via email, providing an audit trail of all user data activities. This function helps personnel maintain operational efficiency, uphold quality assurance and meet regulatory compliance.

The Sentinel system constantly communicates a signal to the Sensaphone cloud to validate its online status. If the communication link is interrupted—for example by a power outage or someone accidentally switching off the unit—the system generates an alert indicating that internet connection is lost. Users are notified about the disruption through phone, text or email.

The user-friendly system lets users change settings, disable alarms and readjust temperature limits from the Sensaphone iPhone/Android app or
