The Greenspan CS4-1200 also measures Conductivity, Dissolved Oxygen, Temperature and pH from one unit and is suitable for river surveys, esturine monitoring, wastewater discharge and groundwater monitoring. This unit uses the SDI-12 protocol to output all data readings.
The CS4-1200 contains a microprocessor to provide temperature and linearity compensation, and to control both the offset and full scale settings. This allows for adjustments if and when required, as part of regular maintenance. These features are implemented with the extended SDI-12 commands. The CS4-1200 is available with either a delrin (plastic) or stainless steel body and can be provided in a variety of ranges.
