Stop Clock Manufacturer,Supplier and Exporter in India

Stop Clock (Product Code: SCL236/018) is a spring-wound mechanical stop clock used to time pendulum swings, cooling curves and other intervals in student labs and classroom demonstrations. Its dial is about 100 mm across with big pointer hands that can be read from a distance, and one complete winding runs it for about 30 hours. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its physics lab equipment for schools.

Specifications

What Is the Stop Clock Used For?

The classic use is the simple pendulum: students release the bob, start the clock on a chosen swing, count twenty oscillations and stop it, then divide to get the period. It is equally useful for taking a temperature reading every minute in a cooling experiment, timing a trolley or ball, and pacing any demonstration where the whole class needs to see the elapsed time.

Wind the clock fully before the lesson so it runs through the day, stop it before pressing the reset lever, and let the sweep hand pass zero before starting the first reading. Because it needs no batteries, it is a reliable standby even where power is uncertain. Keep it upright on the bench and away from water.

Frequently Asked Questions

Does the Stop Clock need batteries?
No. The Stop Clock is spring-wound, so it needs no batteries or power supply. One complete winding runs it for about 30 hours, enough for a full day of practicals with plenty to spare.

How is the time read on the Stop Clock?
The Stop Clock has a main dial about 100 mm across with a large sweep hand reading seconds in 1 s divisions, and a smaller dial reading 0–60 minutes in 1 min divisions. The big pointer hands can be read from a distance.

How are start, stop and reset operated on the Stop Clock?
On the Stop Clock, a lever on the left side starts and stops timing and a separate lever on the right side resets the hands to zero. Stop the clock before resetting to protect the movement.

Who supplies the Stop Clock?
The Stop Clock is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges, dealers and importers in India and international markets. Ask through the contact page if you need details of the maker.
