Nortek Multi Parameter Probe: 10/2010

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

Hitting the Water

Jarno deploys the NMP800 in the Amsterdam harbour

Since it is a Water quality probe we supposed it would be a good idea to take it out in the field and measure some real water. This picture was taken while deploying the probe in the Amsterdam harbour, just before we lowered it to 9 meters deep.
For what it's worth (and if you ever consider swimming here..), here are the results:
