CDMA Cellular Modem for 6700 Series Samplers

CDMA communication enables alarms, data retrieval, and sampler control for remote sites

CDMA Cellular ModemTeledyne ISCO 6712 and Avalanche® portable samplers are often deployed in locations that lack utility lines. This cellular modem provides wireless digital communication, reducing the need for costly trips to monitoring sites that are distant and/or difficult to get to, including rural watersheds as well as manholes in high-traffic urban arterials. It allows the sampler to transmit text message alarms to a text-enabled phone or pager, and to communicate with a modem-equipped PC for remote data retrieval and control. 

The modem is compatible with user-subscribed CDMA digital cell phone service such as Verizon, and Telus (Canada). CDMA service is available throughout most of North America, and many other parts of the world.
