4 PENTAIR ENVIRONMENTAL SYSTEMS MP SERIES SENSOR USER MANUAL

1 Introduction 1.1 System Description Thank you for purchasing a Greenspan MP Series Sensor (Model MP47 or MP65). This manual provides a guide to the configuration, operation and maintenance of your sensor to provide long term reliable and accurate monitoring. The Greenspan MP Series sensors provide a complete self-contained measurement and data logging system for a wide range of environmental water monitoring applications. The sensors provide the ability to measure single or multiple water quality parameters (up to

4 parameters on the MP47 and

6 parameters on the MP65) within the single sensor providing users the choice to select the parameters which best suits their application. Users have a choice of the following parameters: ? Pressure ? pH ? Oxygen Reduction Potential ? Electrical Conductivity ? Temperature ? Turbidity ? Optical Dissolved Oxygen Customers can choose various combinations of parameters to measure. Options available are shown below: OR MP47 Depth pH ORP EC Inline Option
