Equipment - Groundwater monitoring equipment



The CTD-Diver is an accurate, multi-parameter groundwater datalogger instrument.


The CTD-Diver multi-parameter groundwater monitoring instrument is constructed with a durable ceramic casing making it impervious to potentially corrosive substances that may be found in some groundwater environments.


Groundwater quality recording


Frequent monitoring of soil and groundwater quality is traditionally a labour-intensive job.  This is also the case if saltwater intrusion or pollution at remediation sites needs to be monitored.


Amplus can offer multi-parameter groundwater monitoring using the latest CTD-Diver by Schlumberger Water Services.  The CTD-Diver is a fully stand-alone datalogger with built-in memory, battery and sensors.  Its ceramic casing and unparalleled conductivity measuring range (0-80 mS) make the CTD-Diver suitable for use at every measuring site.


The CTD-Diver is impervious to the most aggressive substances found in water environments.  Its ceramic casing resists when even the strongest metals yield.


It is a highly reliable, compact datalogger for the simultaneous measuring of groundwater level, temperature and conductivity.  These parameters are measured at time intervals predetermined by the user.  The measured values are stored in the datalogger’s memory and can be read out at any given time.


CTD-Diver Benefits


  • Frequent, long-term measuring without human intervention
  • Reliable and accurate measurement data
  • Easy calibration


 Professional applications of the CTD-Diver include:


  • Aquifer storage and recovery projects
  • Salinization projects
  • Saltwater intrusion projects
  • Discharge monitoring
  • Monitoring landfill sites
  • Monitoring groundwater and surface water


The CTD-Diver is supplied with the LoggerDataManager (LDM) software package


The installed CTD-Diver cannot be seen above ground level, which keeps the risk of vandalism to a minimum.  Unlike many other systems, the CTD-Diver does not need a vented cable leading to the surface.  The system is entirely closed and moisture penetration is impossible.
