Nortek Multi Parameter Probe

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.
Supported sensors:
- CS547 Conductivity / Temperature
- OBS-3+ Optical Backscatter
- CS525 ISFET pH probe
- InsiteIG Dissolved Oxygen/Temperature
- Valeport miniCT (replaces the CS547)
- Ponsel OPTOD-Dissoved Oxygen Sensor
- Chelsea Instruments TriLux - Blue-algea, Chlorophyll, Turbidity
- Ponsel C4E - Conductivity / Temperature
Internal sensors:
- Pressure (optional)
- Internal temperature
Derived parameters:
- Salinity
- Dissolved oxygen in mg/l

Artist Impression

A first impression on how it is going to look. A PE-Tube with removable end-caps. The end-caps contain the connectors for the sensors and the power/ communication cable.
The caps are held in place by the stainless steel frame which also supports and protects the sensors. All construction drawings are complete and can be sent to the manufacturers.
