The LogTag® UTRED30-WiFi is a dual-channel WiFi temperature logger for accurate, continuous real-time monitoring. Data is automatically uploaded to LogTag® Online, where it is safely stored and easily accessible.
In the event of temperature deviations, you receive an immediate notification via phone, SMS or WhatsApp (with a LogTag® Online subscription), allowing you to respond quickly. The logger features a clear LCD display, resettable min/max display and complies with international guidelines for vaccine storage and monitoring (CDC, FDA, VFC, NIH, PHAC, AAP).
A Vaccine Kit is optionally available.
