ALERT210 ALERT2 Advanced Remote Data Platform with 6 Sensor Inputs, CR800, and AL200
Services Available


The ALERT210 is an advanced ALERT2 transmitter that is designed to be a drop-in replacement for existing flood warning stations. Designed to be flexible, reliable, and low cost, the ALERT210 uses the AL200 modulator and sensor interface, the industry-standard Maxon SD125E-series radio, and the powerful CR800-series datalogger. The ALERT210 includes seven standard circular connectors for sensor and power inputs, as well as two cable glands for additional inputs.

The modular design of the ALERT210 transmitter allows for alternate configurations, additional peripherals, and easy replacement of individual components. Because the ALERT210 is built around the CR800 datalogger, many additional communications options are available. In addition, any ALERT210-series transmitter can be converted to use the ALERT (legacy) protocol with a simple, free firmware change.

Note: ALERT2 is a trademark of the National Hydrologic Warning Council.
