Frontline medical and cold chain staff know how fragile vaccines are. Every batch of vaccines is highly sensitive to temperature changes, and improper storage temperature will directly compromise vaccine quality and effectiveness. To solve this common monitoring pain point, our Coeus-WiFi/4G real-time temperature data logger provides real-time temperature monitoring and alerts for daily vaccine storage.

With dual-probe design, Coeus-WiFi/4G real-time temperature data logger matches diverse vaccine storage scenarios. The built-in sensor fully meets routine ambient monitoring demands, covering a temperature range of -30℃~60℃ at an accuracy of ±0.5℃. Two optional external probes are perfectly suitable for freezer/refrigerator temperature monitoring and ultra-low temperature scenarios, with flexible options of -30℃~+70℃/ -40℃~+85℃/-90℃~+200℃.

Freshliance fully optimizes this device for vaccine compliance standards. It works perfectly with standard propylene glycol buffer bottles in temperature monitoring, which effectively avoids false temperature spikes caused by frequent fridge door openings. This ensures all captured real-time temperature data truly reflects the actual environment surrounding vaccine vials.
With stable WiFi or 4G transmission, the IoT temperature data logger runs non-stop all year round and delivers full-process vaccines temperature monitoring and alerts. Whenever temperatures go beyond safe limits, staff receive instant remote alerts via Email, SMS and APP push.
Powered via Type-C (DC 5V/2A), this vaccine temperature data logger can be easily deployed anywhere with a standard USB port. Additionally, the built-in 2600mAh rechargeable lithium battery, as a backup power supply, can work for up to 60 days at a 15-minute uploading interval. The backup battery delivers higher mobility and ensures uninterrupted environmental monitoring even when the main power is disconnected.
With real-time temperature monitoring and alerts, Coeus WiFi/4G real-time temperature data loggers remove the risk of human error from manual logs and support vaccine cold chains with total confidence.
