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.
