Joulemeter, Student Digital
Joulemeter, Student Digital (Product Code: SLE/PHY/129) is a digital energy meter used to measure the electrical energy delivered to a load in school and college heat and electricity practicals. Designed specifically for student use, it reads from 1 joule to 999,999 joules with 3% accuracy (1% typical) and has a built-in timer that starts and stops with the measurement. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Student Digital Joulemeter Used For?
The Student Joulemeter sits between a low-voltage supply and the load, so students read the energy transferred directly instead of combining separate voltmeter, ammeter and stopwatch readings. It is most often used with an immersion heater in a metal block or calorimeter to find specific heat capacity, and for comparing the energy used by lamps, small motors and heaters.
Because one press of the start button powers the load and starts both the timer and the energy count, and the stop button cuts the power again, every group's readings begin and end at the same moment. Keep the input within 15V AC or 21V DC and the load current below 10A. That combination makes it a practical digital measuring instrument for calorimeter lab work.

Frequently Asked Questions
What range and accuracy does the Joulemeter, Student Digital have?
The Joulemeter, Student Digital measures energy from 1 joule to 999,999 joules. Its stated accuracy is 3%, with 1% accuracy typical, which is suitable for school and college energy-transfer practicals.
What input voltage and current can the Student Joulemeter handle?
The Joulemeter, Student Digital accepts 0V to 15V AC or 0V to 21V DC at most, with a maximum load current of 10A AC or DC. Stay within these limits when choosing the supply and load for an experiment.
How is the Joulemeter, Student Digital powered?
The Joulemeter, Student Digital runs from a 9V DC mains adaptor, which is included. Inside, a microprocessor combined with a precision voltage multiplier calculates the energy, and results appear on a 2 x 16 character LCD.
How does the built-in timer on the Student Joulemeter work?
On the Joulemeter, Student Digital, the start button starts the timer and joulemeter together and powers up the load. The stop button stops both and disconnects input power from the load, so energy and time are recorded over exactly the same period.
