The Nortek Multi Parameter Probe is a stand alone water-quality data collection system for use in harsh environments. Basically it is a combination of field-proven sensors packaged in a robust delrin and brass frame. Data collection and control is handled by a standard Campbell Scientific CR-800 datalogger, packaged in a sturdy PE-plastic pressure housing. This provides a proven stable platform for data collection and retrieval and allows for easy customisation. Data is logged internally or may be output in a NMEA compatible format over RS-232. Data can also be read from the instrument using the SDI-12 or Modbus protocols. When a GPRS modem is connected all data is automatically sent to an FTP server.
