There are many reasons to measure and monitor environmental water quality, chief among them compliance with local, state, or federal requirements. Other applications may call for water quality monitoring for environmental studies of various types. A sonde is an instrument used to collect water quality measurement data in the field. Whatever the issues driving a need for gathering environmental water data, selecting an instrument that combines accuracy, ruggedness, and ease of use can minimize the time and cost involved. There are a number of features to look for.

  • Corrosion resistant construction that tolerates a wide range of targeted water sources.
  • Minimized and simple setup procedure for quick deployment
  • Low maintenance burden
  • Smart sensor technology for best accuracy
  • Extended measurement range for all parameters to accommodate broad range of water sources
  • Low training requirement for technicians to be proficient at deploying sonde in the field
  • Minimal sensor drift to increase available time in field and accuracy
  • Modest or low frequency requirement for sensor calibration
  • Sensor measurement stability. Higher level allows longer field deployment intervals.
  • Sensors that are easily changed or replaced without need for high levels of technical training. Also allows for reconfiguring measurement scheme to target different constituents in the water.
  • Sensors available for RDO, pH/ORP, turbidity, conductivity, temperature, pressure
  • On board diagnostics monitor instrument operation for error
  • Active and passive anti-fouling systems to automatically clean sensors, removing foreign matter that can impact measurements
  • Extended field deployment time with low power consumption
  • Real time data access, as well as on board data storage and other options for flexible data delivery.
These are some of the features that can result in effective data gathering and reduced manpower requirements to accomplish the task at hand.
