Calorimeter Set, Copper, Joules
Calorimeter Set, Copper, Joules (Product Code: SLE/PHY/142) is an electrically heated calorimeter used to find the specific heat capacity of a liquid by Joule's electrical method in senior-school and college physics labs. A Constantan coil of about 6 ohms, fed through two 4 mm sockets in the ebonite lid, runs at 0.5 A (1 A maximum) inside a lagged, nickel-plated copper vessel. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Joule Calorimeter Used For?
Joule's method equates electrical energy with heat. The energy put in by the coil, voltage × current × time, or the reading on a joulemeter, is set equal to the heat gained by the liquid plus the heat gained by the copper vessel, and the only unknown left is the specific heat capacity of the liquid. Recording the temperature every half minute also lets students plot a heating graph and apply a cooling correction.
As a calorimeter experiment kit for India's Class 11 and 12 thermal physics practicals, the set needs only a low-voltage supply, meters and a thermometer. Constantan is chosen for heating coils because its resistance changes very little as it warms, so the current stays steady. Switch on only when the coil is fully covered by liquid, and keep stirring throughout the run.
What to Specify When Ordering
- Number of sets for your practical batch.
- A thermometer for each set, since none is supplied; state the type or ask us to suggest one.
- A low-voltage supply able to deliver 0.5 A (1 A maximum) and leads with 4 mm plugs.
- Either an ammeter and voltmeter pair or a joulemeter for measuring the energy supplied.
OEM Manufacturer
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM for the Calorimeter Set, Copper, Joules and builds it at the company's own licensed factory at Saha, Ambala, Haryana, India. Buying from the manufacturer means requests for a spare lid, stirrer or coil, and repeat orders for new batches, go to the people who make the set; ask us what is currently available.

Frequently Asked Questions
Why is it called the Calorimeter Set, Copper, Joules?
The Calorimeter Set, Copper, Joules takes its name from Joule's electrical method, in which a known amount of electrical energy heats a liquid. Comparing that energy with the temperature rise gives the liquid's specific heat capacity.
How is the specific heat capacity calculated with the Calorimeter Set, Copper, Joules?
With the Calorimeter Set, Copper, Joules, the energy supplied (voltage × current × time) equals the mass of liquid × its specific heat × temperature rise, plus the same product for the copper vessel. Rearranging gives the liquid's specific heat capacity.
Can a joulemeter be used with the Calorimeter Set, Copper, Joules?
Yes, a joulemeter can be connected between the supply and the 4 mm terminals of the Calorimeter Set, Copper, Joules to read the energy directly. This saves timing and multiplying, and students can focus on stirring and temperature readings.
What current should the Calorimeter Set, Copper, Joules be run at?
The Calorimeter Set, Copper, Joules should be run at 0.5 A, with 1 A as the maximum. Its Constantan coil is approximately 6 ohms, so a low-voltage supply is enough to drive the recommended current through it.
Does the Calorimeter Set, Copper, Joules include a thermometer?
No, the Calorimeter Set, Copper, Joules is supplied without a thermometer. Choose one that reads the temperature range of your experiment and add it to your enquiry so it can be quoted with the sets.
Who manufactures the Calorimeter Set, Copper, Joules?
The Calorimeter Set, Copper, Joules is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders come from the manufacturer directly.
What should a quotation request for the Calorimeter Set, Copper, Joules include?
For the Calorimeter Set, Copper, Joules, state the product code SLE/PHY/142, the number of sets, and whether thermometers, a power supply or a joulemeter should be added. Include the delivery address for India or export shipment.
