| Greenspan Multi-Parameter Instrument |
| model CS304 |
| The Greenspan CS304
sensor facilitates the collection of multi-parameter data including: • pH • Conductivity • Temperature • Dissolved Oxygen The compact, lightweight design of the sensor allows for easy deployment. This, combined with a 0.5MB standard memory capability (upgradable to 1MB), ensures cost savings as the sensor can be left unattended in the field longer. The unique design of the DO sensor requires no moving parts ensuring longterm reliable field operation and low power consumption. The new patented diffusion rod sensor technology provides excellent linearity and repeatability. The sensor is compatible with all standard Greenspan interface boxes. It can be calibrated to initiate an automatic sampler for further laboratory testing. Cable fitting can be either integral or detachable, providing easy removal for re-calibration and when combined with a battery pack, allows deployment with no visible surface exposure. This can eliminate vandalism where sensors are to be placed in public waterways. With remote dial-in you can retrieve, view and graph data or reprogram the logging schedule from the comfort of your office. An electronic rain gauge can also be connected to link in rainfall data. Designed and built in Australia and supported by Greenspan's one year warranty, the Greenspan CS304 provides a remarkably compact, multi-parameter sensor that sets the standard for accurate, reliable, long-term water quality monitoring. |
