Why Monitor Water Quality?

What each parameter tells you about the system you're protecting.

Dissolved Oxygen

Controls fish survival and ecosystem health.

Low DO triggers fish kills and signals stressed water bodies. Continuous DO is the single most important indicator for aquaculture and coastal management.

pH

Indicates water chemistry stability.

pH shifts affect nutrient availability, metal toxicity and organism health. Stable pH is a baseline for ecological balance and treatment process control.

Chlorophyll & Algae

Measures algae activity and bloom risk.

Chlorophyll-a and blue-green algae fluorescence give early warning of eutrophication and harmful algal blooms before they impact water supply or fisheries.

Ammonia & Nitrate

Early indicators of pollution.

Nitrogen species flag agricultural runoff, sewage discharge and industrial loading. Real-time monitoring enables source attribution and rapid response.

Sensor Series

Choose the right form factor — fixed-station industrial or portable handheld.

AquaSense Series

In-situ industrial sensors

Single-parameter and multi-parameter sondes for unattended deployment — DO, pH, ORP, conductivity, salinity, turbidity, TSS, COD, ammonia, nitrate, chlorophyll, BGA and oil-in-water.
