An all new 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.

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.

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

Wireless Communication – Remote options include cellular and satellite communications.

Measurement Versatility – SensorBUS technology incorporates industry standard SDI-12, RS-485 and RS232 interfaces in a single watertight cable. Smart sensors are available for most environmental measurements.

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.

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.

Notes
¹Range varies based on many factors including obstructions, other wireless signals in the area, elevation change, and more. Actual distances may vary by location.
²Assumes 25°C operating temperature
³Requires the X2 to be connected to the internet
⁴Minimum log interval dependent on sensor limitations and processing time
⁵Cumulative concurrent current limit of all three channels is 2A
⁶Logger power supply must be able to support current requirements of sensors
