Pen Meter Conductivity TDS & pH

This multi-function Pen Meter is a powerful, all-in-one tool that measures conductivity, total dissolved solids (TDS), and pH-making it ideal for comprehensive water quality analysis. Designed for high school labs, field studies, and science classrooms, this device supports diverse experiments across biology, chemistry, and environmental science. Its integrated design reduces the need for multiple instruments, providing a compact and practical solution for students and educators.

With a broad range of applications-from tracking nutrient levels in hydroponics to monitoring environmental water samples-this meter supports accurate measurement with automatic temperature compensation. The large LCD includes a secondary information line for simultaneous data readout, while the robust ABS housing and replaceable electrode design offer durability and longevity. Simple three-button operation and clear readings make it easy for students to use effectively.

Educational Benefits:

• Consolidates three critical measurements (pH, conductivity, and TDS) in one device
• Reinforces cross-disciplinary learning through water quality analysis
• Teaches real-world scientific processes with practical instrumentation
• Encourages independent investigation and data interpretation skills

Classroom Ideas:

• Monitor changes in water chemistry across different ecosystems or school water sources
• Compare TDS and conductivity in natural, tap, and filtered water
• Study how fertiliser concentration affects pH and conductivity in plant-growing experiments
• Conduct long-term tracking of water quality for sustainability or environmental science units
