Pen Meter TDS 0.0-100 mg.L

This Pen Meter is a convenient and durable solution for measuring Total Dissolved Solids (TDS) in educational and laboratory settings. Designed with simplicity and functionality in mind, it allows students and educators to obtain accurate readings of dissolved ionic content in water-based solutions. This makes it especially useful in environmental science, chemistry, and water quality investigations. With a resolution of 0.1 mg/L and a range from 0.0 to 100.0 mg/L, it delivers reliable measurements in a straightforward and efficient manner.

Constructed with an easy-grip body and a clear LCD screen, the Pen Meter is intuitive for students of all ages to use. Its lightweight and compact design, along with a waterproof casing and auto-shutoff feature, ensures longevity and portability. This meter promotes active learning and helps students develop a practical understanding of solution concentration and water purity analysis through direct observation and experimentation.

Educational Benefits:

• Teaches students how to test and interpret TDS levels in liquids
• Reinforces curriculum outcomes related to water purity and chemical properties
• Develops familiarity with scientific instruments and digital readouts
• Encourages inquiry, analysis, and data comparison in science investigations

Classroom Ideas:

• Compare TDS in tap, bottled, and rainwater for science or geography projects
