MP & MQ Multi-Parameter Water Quality Sensors

Greenspan’s range of sensor modules can be fitted together in certain combinations to allow for multiple water quality parameters within a single sensor. The 47mm diameter MP series can have up to 3 sensors recording up to 4 parameters (temperature and EC are in a single sensor), and the 65mm MQ series can have up to 5 sensors recording up to 6 parameters. Contact us to check which sensor combination and model will best suit your requirements.

• Pressure (water level)
• pH
• Oxygen Reduction Potential
• Electrical Conductivity
• Temperature
• Turbidity
• Optical Dissolved Oxygen



  • MP=47mm diameter main body
  • MQ=65mm diameter main body
  • PS=Pressure
  • EC=Electrical Conductivity and Temperature
  • PH=pH
  • OR=Oxygen Reduction Potential
  • DO=Optical Dissolved Oxygen (end sensor only)
  • TS=Turbidity (end sensor only)

Common models:

  • MP-2-PS-EC
  • MQ-2-PH-EC
  • MQ-3-PH-PS-EC
  • MQ-3-PH-EC-DO
  • MQ-4-PH-PS-EC-TS

Note that EC with PH and/or OR currently require the MQ body, and DO and TS can only be placed at the end of the sensor body. Contact us to discuss your requirements. Maximum parameter measurement is MQ-5-PH-PS-EC-OR-TS/DO measuring 6 parameters: pH, water level (pressure), electrical conductivity, temperature, oxygen reduction potential, and either turbidity or dissolved oxygen.
