Aquamonix MP47/MP65

Multiparameter sondes



  • Can be installed in active waters (acidic or salty conditions)
  • Reliable and robust sensor ensures minimal servicing visits
  • Suitable for marine applications and waterways with high sediment loads
  • Easy to configure logger – quick retrieval of data using SensorMate softwares
  • Graphical and tabular display – export to spreadsheet format
  • Standalone operation with on board battery pack
  • Various cable options for telemetry and integration applications

The Aquamonix MP47 and MP65 multiparameter 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

The sensor includes an internal data logger to provide long term data collection at remote sites. The sensor can be fitted with an external cable, or with an on-board battery pack for true standalone operation. Serial output (RS232 or RS485) in Modbus or optional SDI12 allow connection to an external data logger or process controller as well as options for remote telemetry connection.

  • Low power usage enables long term remote operation
  • Internal data logger for collection of data during critical events
  • Telemetry options via mobile phone, radio and satellite
  • SDI12 cable adaptor unit for connection into data logger or controller
  • Modbus RTU or ASCII
  • RS232 or RS485/422

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
