The Aquaculture Water Test Kit – pH & Salinity is a complete, application-specific kit designed for aquaculture and shellfish farming, where pH and salinity are critical to animal health and harvest decisions.

Seawater is naturally slightly alkaline, so this kit is supplied with pH 6.86 and pH 9.18 buffers to calibrate accuracy in the range oysters and other shellfish actually experience. A 35 ppt salinity calibration solution is included to support reliable salinity measurement in marine and estuarine environments.

This kit is ideal for:

• Oyster and shellfish farming
• Estuarine and coastal water monitoring
• Manual salinity checks after rainfall or freshwater inflow
• Routine pH and salinity verification

What’s included

• 5-in-1 probe (pH, EC/salinity, temperature)
• KCl storage solution (for correct probe storage)
• pH buffer 6.86
• pH buffer 9.18
• Salinity calibration solution – 35 ppt (50 mL)
• 3 Calibration cups (one per solution)

Everything required for correct calibration, measurement, and probe care is included.

Why this buffer combination is used

Seawater and estuarine environments are typically neutral to mildly alkaline. Using pH 6.86 and pH 9.18 ensures calibration accuracy across the pH range most relevant to aquaculture, rather than acidic ranges that are rarely encountered.

Recommended applications

• Aquaculture & shellfish farming
• Marine and estuarine monitoring
• Salinity-sensitive environments
