Features

Watertight Housing

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.

Underwater Connectors

Underwater Connectors

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

Device-to-Web

Device-to-Web

When communicating within a Wi-Fi network or connecting via remote telemetry, measurement data streams directly to the datacenter.

Wireless Communication

Wireless Communication

Wi-Fi provides short range and local connectivity. Remote options include radio, cellular, and satellite communications.

Measurement Versatility

Measurement Versatility

SensorBUS technology incorporates industry standard SDI-12, RS-485 and RS-232 interfaces in a single watertight cable. Smart sensors are available for most environmental measurements.

Easy Install

Easy Install

A specially designed mounting bracket holds the X2 to a 2" NPT pole for easy connection. The optional solar power pack also mounts to the pole and provides ample power for most applications.

Smartphone Interface

Smartphone Interface

A smartphone, tablet, or laptop connects by Wi-Fi to access sensor data and view or change settings. No application-specific hardware or software is required. Works within an existing Wi-Fi network or as a direct link from the X2 to the device.

Case Studies

Katharine Ordway Natural History Study Area

Inspired by a passion for the outdoors and the local terrain that Katharine Ordway had throughout her life, the Katharine Ordway Natural History Study Area (Ordway) at Minnesota's Macalester College is a study in diversity. To preserve the conservation legacy that serves as Ordway's foundation, its mission includes four pillars: education, research, sustainability, and civic engagement. The environmental monitoring that supports that mission is widely varied—and it takes special planning […]

Using Technology to Protect Tradition

The Nottawaseppi Huron Band of Potawatomi (NHBP) is facing the future with a firm grasp on tradition and a mastery of new technology to handle rapid growth and changes. Recognized as a tribe by the US federal government in 1995, the NHBP employs thousands in western and central Michigan. Since its inception, restoring its land which now spans over 1,000 acres and fostering environmental stewardship for the good of the […]

Wetland Research And Management

Wetlands the world over are important for a lot of reasons. For one, they are predicted to help buffer the effects of rising sea levels predicted alongside other effects of climate change globally. But on a more local scale, wetlands are important because they act as large living filters that increase water quality while at the same time providing habitat for large numbers of waterfowl and amphibian species. This is […]
