GoCoChain · Real-Time Monitoring
CoTag Connect
Designed for warehouses. CoTag Connect watches your cold rooms and warehouses around the clock and alerts you the moment a temperature drifts — before cargo is lost, not after.
It replaces the three problems every cold-chain operator knows: freezer failures noticed too late, hours lost to manual temperature recording, and audit records scattered across paper forms.
How It Works
Sensors. Gateway. Answers.
01 · SENSE
CoTag Sensors
Compact 16 g sensors with a professional probe rated from −50°C to 100°C log the temperature every 5 minutes, in an IP65 splash-proof body (IP68 with the external probe).
02 · CONNECT
Gateway LTE
One gateway relays data from up to 30 CoTag devices via 4G (built-in SIM), Wi-Fi or Ethernet — no existing network infrastructure required.
03 · MONITOR
App & Dashboard
Real-time temperatures with customizable alert ranges per product. Set a threshold, get alerted when it breaks, and export reports on demand.
Live in About 1 Hour
Professional on-site installation with no wall drilling and no interruption to your cold chain operations.
