Student Digital Joulemeter
Product Code : JA-M-7834
The Student Digital Joulemeter (SKU JA-M-7834) is a compact bench meter that measures the electrical energy supplied to a load in student heating and power experiments. This student digital joulemeter handles loads up to 10 A AC or DC at up to 15 V AC or 21 V DC, and its built-in timer starts and stops together with the energy count and the power to the load. JaincoLab manufactures it in India for school and college physics laboratories.
Specifications
The Student Digital Joulemeter accepts up to 10 A AC/DC load current at 0–15 V AC or 0–21 V DC, uses a microprocessor with a precision voltage multiplier, shows results on a 2 × 16 character LCD with a built-in timer, and measures 90 × 90 × 33 mm.

Applications of the student digital joulemeter
Students connect the joulemeter between a low-voltage supply and a heater, lamp or motor, press start, and read the energy delivered and the elapsed time together, which makes specific heat and power experiments quicker and removes separate stopwatch timing.
- Specific heat capacity of solids and liquids with an electrical heater
- Specific latent heat of fusion or vaporisation
- Measuring the energy used and the power of lamps and small motors
- Energy transfer and efficiency investigations in secondary school physics
