The newest generation, our Series 5 multiparameter probes, were designed specially for measurement of water quality in surface waters, ground water and wastewater areas. The new Series 5 includes three types of probes:
  • Minisonde 5 - MS5:
    • Parallel measurement of up to 10 water quality parameters
    • 4 additional sensor inputs for specific applications
    • Compact and light housing with a 1,75' (44,5 mm) diameter for use in groundwater wells
    • Suitable for point-to-point measurement and continuous measurement with data storage
  • DataSonde 5 - DS5:
    • Simultaneous measurement of up to 15 water quality parameters
    • 7 additional sensor inputs for specific applications
    • Unlimited use of all HYDROLAB sensors
    • Suitable for point-to-point measurement and continuous
      measurement with data storage
  • DataSonde 5X -DS5X:
    • Simultaneous measurement of up to 15 water quality parameters
    • 7 additional sensor inputs for specific applications
    • Central brush motor cleans all sensors before each measurement
      and prevents the buildup of biofilms

Hydrolab MS/DS - Series 5 with superior sensor technology
Dissolved Oxygen HACH LDO
Extremely high precision through the use of the optical LDO measurement method (Luminescent Dissolved Oxygen).
Calibrations last up to 1 year. Easy to maintain since no membranes are used.
Clark cell is available as an alternative.
Self-Cleaning Turbidity Sensor
The selfcleaning system can be adjusted according to environmental conditions and can execute up to 10 cleaning cycles prior to every measurement. A measurement range of 3000 NTU permits turbidity measurement even during heavy rain or other events.
Also available: 4-beam turbidity and standard turbidity.
Conductivity
The open cell allows reliable measurements even under the most serious environmental conditions:
Sediment drops down and air bubbles rise. Salt content, electrical resistance and TDS can be individually maintained as calculated values.
pH
The reference electrode can be refilled quickly and easily independent of the pH sensor. The pH sensor doesn’t have to be replaced when the reference electrode is empty.
Depth
Optimized for depths of up to 10 m, 25 m, 100 m or 200 m
ORP
Uses a simple platinum strip that either discharges electrons or absorbs them, so as to observe chemical reactions, determine ion activity or to determine oxidizing or reducing properties of a solution.
TDG (total dissolved gases)
Real-time measurement indicates if water is supersaturated with atmospheric gases, which can lead to gill illnesses.
Chlorophyll a
Very compact size, specially developed for use in HYDROLAB probes Very precise, selective measurement through electronic filtering of ambient light and by using high quality optical components.
Cyanobacteria
Real-time measurement recognizes potential algal bloom early on before it becomes a problem. Very compact size, specially developed for use in HYDROLAB probes Very precise, selective measurement of phycocyanin and phycoerythrin through electronic filtering of ambient light and by using high quality optical components.
Ion-Selective Electrodes
Available for the measurement of ammonium, nitrate or chloride.
