CK201 4G Portable Temperature & Humidity Monitor

CK201 is a portable, installation-free temperature and humidity monitoring device for cold-chain transport, pharmaceuticals, food and other mobile environmental-recording applications. It collects temperature and humidity data and uploads it to the management platform over 4G, while LBS positioning provides an approximate location reference.

The built-in 6000mAh battery supports mobile operation, while offline storage keeps monitoring records when network coverage is unstable. This makes CK201 suitable for cross-border and long-distance cold-chain transportation.
