Digital Stopwatch
Product Code : SCL-PL-11942
Digital Stopwatch (SKU SCL-PL-11942) is a timer reading to 1/100 of a second over a 24-hour range, which also shows the normal time of day, the date and an alarm. In the laboratory it can time pendulum swings, falling objects and reaction rates in school science, college physics and training workshops. Single units or class sets are quoted by Science Lab Supplies, Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.

Applications and Experiments for the Digital Stopwatch
A 1/100 s reading makes this timer suitable for practicals where students time many oscillations or short events and then divide or average. It supports the simple pendulum and motion practicals of Class 9 and Class 11 physics, timed chemistry experiments and B.Sc. mechanics labs.
- Class 11 physics practical: timing 20 oscillations of a simple pendulum to find its period, for example with bobs from the Six-Metal Pendulum Bob Set.
- Class 9 science: measuring time for distance-time and speed calculations, such as a car run on the Dynamics Car and Inclined Track Set.
- Timing a reaction to a colour change in rate-of-reaction experiments.
- Measuring human reaction time as an introduction to timing errors, with a dedicated Reaction Timer for light, sound and touch stimuli.
For short events, the human reaction time is usually larger than the 0.01 s display step, so repeated readings and averaging give better results.
Standard Scope of Supply
The Digital Stopwatch is supplied as a single unit as described above, with its time, calendar and alarm functions. Class quantities can be quoted on request, so each student pair or group can have its own timer, and any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
Whether you need a single stopwatch or one for every student pair, the quotation covers packing, delivery time and price for that number. Pendulums, timers and other physics lab equipment in India can be added to the same enquiry for one combined reply.
With an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Stopwatch prices for one bench or a full class are available through the contact page or the enquiry cart, and institutions buying by tender can begin at the lab tender page.
Frequently Asked Questions
What is the resolution of this digital stopwatch?
It reads to 1/100 of a second (0.01 s) and can also count in 1 s steps, over a 24-hour range, so the same unit covers short swings and long timed runs.
Does it work as a clock too?
Yes. It shows the normal time in hours, minutes and seconds along with the day, date and month, and it has an alarm, so it can double as a desk clock between practicals.
Who supplies the Digital Stopwatch?
A school, institute or tender buyer can order the stopwatch singly or in class sets from Science Lab Supplies in Ambala, India, which states packing and delivery time on each quotation.
Which practicals is it used for?
It suits the simple pendulum, motion and speed measurements, reaction-time exercises and timed chemistry reactions. Its 1/100 s resolution suits short events, while the 24 h range also covers long timed runs.
