X2 Environmental Data Logger

Our flagship data logger offering the latest in real-time monitoring technology with wireless communication, a large plug-and-play sensor library, and ultra-low power consumption.

Features

Watertight Housing

The X2 is sealed in an aluminum housing with a polycarbonate top plate. Magnetically activated keys allow for input without jeopardizing the units waterproof seal. The unit is designed to work in extreme conditions, including underwater.

Watertight Housing

Underwater Connectors

All connections are made with a simple waterproof thread-in connector. This removes the complications and errors associated with connecting individual wires.

Q&A

What sensors are compatible with the X2 data logger?

Bridge telemetry unifies two types of wireless communication methods into a single X2 data logger. Most commonly, it can be used establish a network of radio data loggers that link to a single radio-to-cellular repeater. That way, one cellular data plan is used to transmit data from the entire network, resulting in lower recurring data costs.

How does bridge telemetry work?
