Multiparameter water quality measurements

Scuba water quality probes

The Scuba water quality probes are suitable for various applications. They can be used for discrete sampling and profiling, or as self-powered loggers. Connect them to telemetry stations for continuous real-time monitoring and have your water quality data accessible directly via cloud-based software. The Scuba probes can communicate via RS-232, SDI-12 or Modbus.

Measure multiple water quality parameters

The Scuba probes are highly customisable to meet your needs. Choose your parameters to measure to select the right the sensor for your applications. You can even add a battery pack to turn your field sensor into a monitoring device for several weeks or months.

Why choose the Scuba water quality probes

  • An industry-leading 3 year warranty
  • Long sensor lifetime
  • Customisable, to measure the parameters you need
  • Low maintenance costs
  • Large internal datalogger memory storage for several weeks/months
  • Automatic recording of internal calibration data and sensor health indication
  • Calibration is easy and fast
The water quality parameters that our probes can measure include:
Temperature Chlorophyll, blue-green algae, PAR
Acidity (pH) Crude oil, refined oil
Dissolved Oxygen (DO) CDOM/FDOM, tryptophan
Electrical Conductivity (EC) Fluorescein dye, rhodamine
Oxidation Reduction Potential (ORP) Dissolved CO2
Depth Optical brighteners
Turbidity Ammonium
Nitrate Chloride
Sodium Calcium

Designed for extended use in the field

The Scuba range is equipped with features that ensure carefree use under various circumstances. Optional copper gauze slowly dissolves in water, bathing the sensors with copper ions that prevent biofouling. Additionally, the larger probe models (Scuba 75, 90 and 105) feature a wiper system to keep your sensors clean.

Every Scuba probe features:

  • Anti-corrosive housing
  • TLED status indicators on each sensor that provide important diagnostic information
  • Robust marine bulkhead connectors
  • Direct, Bluetooth or telemetry connection
  • User-friendly and intuitive software for iOS, Android, and Windows

Low maintenance costs

The Scuba probes are low in maintenance costs, partly because the reference sensor is separate which reduces the need for consumables. The optional copper gauze, and wiper in the larger Scuba probes, also help reduce the frequency for necessary maintenance. Depending on the fouling capacity of the water it is placed in, a Scuba can function with maintenance intervals of at least a month or even longer.  

Why measure in the field rather than the lab

Storing and transporting water samples in bottles can change the pH (acidity), EC (electric conductivity) and O2 (dissolved oxygen) of the sample, leading to inaccurate measurements. Pumping samples up to the surface and storing in the bottle can raise oxygen levels, while settlement of hydroxides influences EC. Analysis in the field is therefore, in most cases, preferable. 

Easy Scuba: for budget-friendly water quality measurements

If the regular Scuba probes are too advanced and expensive for your requirements, you can opt for the simplified and more budget-friendly Easy Scubas.
