At the Heart of Coastal's Weather Stations

Coastal’s two ZENO dataloggers, the original ZENO 3200 and the ZENO 6800, are built specifically for environmental monitoring, and both offer sophisticated processing abilities.

ZENO dataloggers work with virtually any sensor and means of communication, and consume very little power. ZENO is the ideal choice for use in remote applications and extreme environments.

Key Features

ZENO® 3200

ZENO 3200 employs a 32-bit microcontroller for fast computing. The user interface is an easy-to-use menu format that allows you to integrate other sensors, select data processes, and select suitable communication parameters.

ZENO® 6800

ZENO 6800 offers more serial channels and higher accuracy, and features a powerful ARM-9 microcontroller for even faster processing than the ZENO 3200. Direct Ethernet connectivity, Wi-Fi capability, and support of Modbus TCP/IP and RTU, are also defining features of the ZENO 6800.
