Calorimeter, Electric
Calorimeter, Electric (Product Code: SLE/H/12) is an electrically heated calorimeter for experiments in which a measured current warms a known quantity of water, so students can compare the electrical energy supplied with the heat the water gains. Its moulded cover carries a 1.5-ohm heating coil with standard binding posts, and the unit operates at 4 A from a 6-V lantern battery. Physics teachers in secondary schools, junior colleges and teacher-training labs use it for specific heat and electrical-energy practicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its calorimeter lab equipment for schools in India and international markets.
Specifications
| Parameter | Detail |
|---|---|
| Type | Electrically heated calorimeter with heating coil in the cover |
| Heating coil | 1.5-ohm coil mounted in a moulded cover |
| Operating current | 4 A |
| Power source | 6-V lantern battery (not included) |
| Electrical connections | Standard binding posts on the cover |
| Coil protection | Supporting posts and coil coated to prevent electrolysis |
| Supplied with | Insulated stirrer, single-hole rubber stopper and instructions |
Typical Use
In a standard practical, students pour a weighed amount of water into the calorimeter, fit the cover so the coil is immersed, and hold a thermometer in the single-hole rubber stopper. The binding posts are then wired to the 6-V lantern battery, the coil carries its 4 A working current, and the class stirs gently with the insulated stirrer while noting the temperature every half-minute or so. From the current, the coil resistance and the heating time they calculate the electrical energy delivered and set it against the heat absorbed by the water, which opens a discussion of heat losses and specific heat capacity.
The coating on the coil and its supporting posts prevents electrolysis while they sit in water, so the measured temperature rise comes from resistive heating rather than chemical side reactions. Practical tips: switch off between runs so the battery is not drained, keep stirring at an even pace for uniform water temperature, and dry the vessel and cover after the lesson. It is a compact addition to school physics lab equipment in India and elsewhere wherever heat and electricity are taught together.

Frequently Asked Questions
Is the 6-V lantern battery included?
No. The calorimeter needs a 6-V lantern battery, which is not included and is normally sourced locally.
What current does the heating coil draw?
The unit operates at 4 A through its 1.5-ohm coil, so use connecting leads and a source that can handle that current.
What comes with the calorimeter?
An insulated stirrer, a single-hole rubber stopper and instructions are supplied along with the calorimeter and its coil cover.
Why are the coil and posts coated?
The coating prevents electrolysis while the coil is immersed in water, keeping the experiment about heating and protecting the coil over repeated use.
Is a thermometer supplied?
A thermometer is not listed among the included items. A suitable one can be added to your order — contact us with your requirement.
Can a calibration certificate be provided?
This is a teaching calorimeter; if your institution needs any calibration documentation, please discuss it with us through the contact page before ordering.
What warranty applies?
Warranty terms are confirmed with each quotation — ask us for the current terms.
Do you supply schools in bulk or overseas?
Yes. We supply schools, colleges and distributors in India and international markets; share the quantity and delivery location when you enquire.
