Why Buy From Fondriest?


The iSIC digital expansion gives a single iSIC data logger the ability to support up to six independent RS-232 digital sensor connections. Since RS-232 is not a multi-drop bus like RS-485 or SDI-12, each RS-232 sensor connection requires it's own dedicated port on the data logger.

Common RS-232 sensor connections include sondes, flow meters, sonars, altimeters, GPS units, and mass spectrometers; however any environmental sensor that communicates as defined by the RS-232 standard can be connected so that data can be accessed via iChart software.
Notable Specifications:
  • RS-232 Interface: (3) RS-232 sensor ports
  • Host Interface: (1) RS-232 host port
  • Supported Serial Communication Protocols: NMEA 0183 or Modbus RTU
  • Power Outputs: Includes additional 12 V 100 mA configurable switch access point

Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.

BOB and MARI Will Monitor Water Chemistry in the San Francisco Bay

Scientists have had nagging questions about how ocean acidification might be affecting the waters of the San Francisco Bay. But if you can't trust BOB and MARI with your research questions, who can you trust? That's BOB, the Bay Ocean Buoy and MARI, BOB's companion mooring for Marine Acidification Research Inquiry, of course. BOB and MARI are a bright yellow, five-foot tall buoy and its companion mooring, respectively. They are anchored near the Estuary and Ocean Science (EOS) Center of San Francisco State University (SFSU). SFSU researchers are collaborating with scientists from the University of California, Davis and other funders and partner organizations on the first long-term project to monitor carbon dioxide and ocean acidity in the San Francisco Bay.
