School Digital Stopwatches
Product Code : SCL-PL-12299
School Digital Stopwatches (SKU SCL-PL-12299) are 1/100-second digital timers with lap and split timing, a countdown timer, and a clock with date and alarm, powered by one LR44 cell. They suit pendulum, motion and reaction-time practicals from middle school to college. Science Lab Supplies in Ambala, India, can quote them in class-set numbers for schools, colleges, training institutes, tender contractors and distributors.
Specifications
The table lists each function and part of the black school stopwatch. In short, it reads to 1/100 s on a large display, has separate start/stop and reset buttons, records lap and split times with memory, doubles as a countdown timer, clock, calendar and alarm, and runs on a single LR44 button cell.

Applications and Experiments for the School Digital Stopwatches
A stopwatch is the basic timing tool of the school physics lab. These units time oscillations, falling objects and trolley runs to a hundredth of a second, and lap and split modes let one student record several intervals in a single run. They also serve biology and sports activities.
- NCERT Class 11 physics: time period of a simple pendulum and its dependence on length.
- Class 9 science: speed and motion experiments with measured distances and times, for example timing the Constant Speed Car over a marked track.
- Reaction-time and pulse-rate activities in biology and physical education.
- Counting oscillations, or the revolutions of the Anemometer Model 4-cup, over a fixed interval.
For pendulum work, time 20 oscillations and divide, because a person’s reaction time is much longer than the 1/100 s display step.
Standard Scope of Supply
The School Digital Stopwatches are supplied as individual units as described above, each running on one LR44 cell. The number of stopwatches for your class set, and any spare cells you want, are stated item by item on the quotation.
Packing, MOQ and Lead Time
You can ask for a quotation for a handful of stopwatches or a full class set; Science Lab Supplies states packing, delivery time and price for that number. Pendulum sets and other physics lab equipment in India for timing practicals can be added.
With an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Say how many stopwatches each lab needs on the contact page, or add them to the enquiry cart with other timing items; purchases made by tender go through the lab tender page.
Frequently Asked Questions
What is the timing resolution?
The stopwatches read to 1/100 s and have separate start/stop and reset buttons, so a timing can be stopped and cleared without mistakes during practicals.
Can they record lap and split times?
Yes. Lap and split timing are both available, and results can be stored in memory so a group can read them back after the run.
What battery do they use?
Each stopwatch runs on a single LR44 button cell, which powers the timing modes as well as the countdown timer, clock, date and alarm functions.
Who supplies the School Digital Stopwatches?
They are quoted by Science Lab Supplies, a physics instruments supplier in India based in Ambala, for schools, colleges and trade buyers, either alone or on one quotation with pendulums and other timing apparatus.
Related Timing Apparatus
Timing experiments may call for a second type of timer or an apparatus to time. These items pair with the stopwatches, from another digital model, a mechanical clock and electronic timers to pendulums for the classic period practical, and come from the Physics Lab and Clinical Laboratory ranges, so they can be priced on one quotation.
