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 are used for pendulum, motion and reaction-time practicals from middle school to college. Science Lab Supplies supplies these stopwatches from its base in Ambala, India, to schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each black stopwatch has a large, easy-to-read display and separate start/stop and reset buttons. It records lap and split times, stores results in memory, and also works as a countdown timer, clock, calendar and alarm. Power comes from a single LR44 button cell, and the unit is compact and durable.

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.
- Reaction-time and pulse-rate activities in biology and physical education.
- Counting oscillations or rotor revolutions 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. Enquire through the contact page or the enquiry cart, and see the lab tender page if you are buying under a tender.
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?
Science Lab Supplies, a physics instruments supplier in India, supplies them from Ambala to schools, colleges and trade buyers, and can include them on a quotation with other timing apparatus.
Related Timing Apparatus
Timing experiments may call for a second type of timer or an apparatus to time. These four items from the physics range pair with the stopwatches, from another digital model to photogate timing and a pendulum set, and can be priced on one quotation.
- Digital Stopwatch — 24 h timer with 1/100 s display, date and alarm.
- Analog Timing Experiment Clock — mechanical interval timer for experiments.
- Electronic Timer with Photogates — four optical sensors with a data-storing timer.
- Pendulum Set — steel and aluminium balls on a 1 m cord with an angular scale.
