Energy / Joulemeter – SEP USB Version

Building on the success of the original SEP Energy Meter, this enhanced USB‑enabled Energy/Joulemeter offers improved performance, built‑in datalogging, and expanded measurement functionality. Designed for ease of use in the classroom, the meter provides accurate readings of energy, power, voltage, and current across a wide range of experiments at KS3, KS4, and beyond.

With an intuitive interface and automatic unit scaling, the meter can measure extremely small and very large values—from 100 nanojoules up to 1.75 megajoules—making it suitable for a broad spectrum of physics and energy‑transfer investigations.

Classroom Benefits

Energy is a concept that many students struggle to visualise. This meter provides a powerful way for pupils to measure real energy transfers directly, helping them gain a solid understanding of one of physics' most important ideas: energy is a quantitative tool used to solve problems and answer real‑world questions.

Because the instrument is highly intuitive, students can quickly see exactly how much energy is transferred by different devices or processes. It is suitable for practical work involving:

• Solar panels and motors
• Electrical power investigations
• Energy efficiency experiments
• Comparing components under different loads
• Measuring energy gains and losses in a system

Ideal for School Science Lessons

Perfect for KS3 introduction to energy and KS4 energy calculations, this SEP Energy/Joulemeter supports:

• Developing conceptual understanding of energy transfer
• Hands‑on measurement of power, voltage, current, and energy
• Datalogging activities for analysis and interpretation skills
• Supporting required practicals involving electrical circuits
• Reinforcing energy as a measurable, numerical quantity

Reliable, intuitive, and designed specifically for education, the SEP Energy/Joulemeter is an essential tool for teaching electricity and energy concepts effectively.
