The Environmental Water Quality Testing Kit – 5-in-1 provides a complete system for measuring key water quality parameters in environmental monitoring, education and water management applications.

The kit measures pH, electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature, providing a simple and effective way to investigate water chemistry in rivers, lakes, hydroponic nutrient solutions and aquaculture systems.

Unlike many basic meters, this kit includes multiple calibration and reference solutions, allowing the instrument to be properly prepared before measurements are taken. This ensures reliable and repeatable results and also allows students and users to learn how scientific instruments are calibrated in real measurement environments.

This makes the kit ideal for school environmental science projects, hydroponic nutrient monitoring, aquaculture water management and general water quality investigations.

Parameters Measured

The instrument measures five important water quality parameters:

• pH – acidity or alkalinity of water
• Electrical Conductivity (EC) – concentration of dissolved ions
• Total Dissolved Solids (TDS) – overall mineral content
• Salinity – salt concentration in water
• Temperature – important for environmental monitoring

Together these measurements provide a simple but powerful overview of water chemistry.

Ideal For

• School environmental science projects
• Water quality field investigations
• Hydroponic nutrient monitoring
• Aquaculture water management
• River and lake water studies
• Environmental monitoring programs

Example Environmental Investigations

Students and users can measure:

• rainwater chemistry
• river or creek water quality
• freshwater vs seawater salinity
• agricultural runoff effects
• hydroponic nutrient solution strength
• aquaculture tank conditions

Typical Salinity Reference

The included 35 ppt salinity reference solution allows comparison with typical seawater salinity levels.
