VaxAlert™ Temperature Indicator

VaxAlert

Sensitech Inc.'s most advanced electronic temperature indicator integrates multi-alarm, last-mile cold chain monitoring with detailed time-temperature alarm excursion history information. The VaxAlert indicator enables logistics staff, receivers and quality assurance personnel to determine if and when cold chain breaks occur in the supply chain. The user-friendly liquid crystal display (LCD) combines complete alarm status information with an alarm time-stamp record and the maximum or minimum temperature experienced during the alarm event.

The VaxAlert™ is designed to meet the stringent World Health Organization (WHO) Performance Quality and Safety (PQS) requirements for international vaccine shipment monitoring and is WHO pre-qualified per performance specification WHO/PQS/E06/TR07.1 (Electronic Shipping Indicator). The indicators are factory configured to WHO-established alarm profiles in support of UNICEF vaccine procurement and transport requirements.

In addition, these cost-effective, single-use indicators monitor up to three time-temperature alarms which can be tailored to specific cold chain transport monitoring requirements beyond UNICEF vaccine shipments.
