Student Digital Joulemeter – Edu‑Lab (KS4+)

The Edu‑Lab Student Digital Joulemeter is a compact, robust instrument designed specifically for student use in secondary education and beyond. Suitable for KS4, GCSE, and A‑Level physics, this joulemeter enables students to accurately measure electrical energy in practical investigations, supporting clear understanding of energy transfer and power.

Capable of measuring energy values from 1 joule up to 999,999 joules with a typical accuracy of 99%, the unit combines reliability with ease of operation. Power is supplied via a 9V DC mains adaptor, ensuring consistent performance during classroom experiments.

The joulemeter features microprocessor‑controlled circuitry with a precision voltage multiplier, delivering dependable readings across a wide range of experiments. A built‑in timing function allows the start and stop buttons to simultaneously control the timer, joulemeter, and power to the load, making experiments clear, safe, and easy to manage.
