 | 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.

One of our customers mentioned that all the sensors and cabling was quite open. So far none of our deployments actually suffered from that. Some mud, algae and bio-life does stick between the sensors but it's always easy to remove. However when using the instrument from a vessel at sea its not unlikely that floating debris might hit the sensors and cabling.
