Digital Stopclock
Digital Stopclock (Product Code: SLE/ME/41) is a battery-powered digital timer used to time physics and general science experiments to 1/100 second in school and college laboratories. Its large 12 mm high display and front-panel 4 mm sockets, which let start/stop and reset be triggered externally as well as from the top-mounted push switches, set it apart from a handheld stopwatch. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its physics lab instruments.

What Is the Digital Stopclock Used For?
A stopclock with a display the whole bench can read is ideal for timing pendulum swings, trolley runs down a ramp, falling objects, cooling curves and the rate of simple chemical reactions. The split (lap) function records an intermediate time without stopping the count, so students can note, for example, the time for ten oscillations and then twenty in a single run.
The 4 mm sockets make it possible to wire the stopclock to external switches or contacts, so the clock starts and stops at the exact moment an event happens rather than when a student reacts. This reduces human reaction-time error and is a good way to introduce the idea of systematic error in physics lab instruments work in India's schools and colleges.
What to Specify When Ordering
- Number of stopclocks needed per laboratory or group.
- Whether AA/R6 or HP7 cells should be included with your order.
- Whether you plan external switching through the 4 mm sockets, or light-gate timing, so we can advise on suitable accessories.

Frequently Asked Questions
How precise is the Digital Stopclock?
The Digital Stopclock times in steps of 1/100 second for periods of up to 1 hour. It also offers split (lap) timing, so intermediate times can be recorded during the same run without stopping the main count.
Can the Digital Stopclock be started by an external switch?
Yes. The Digital Stopclock has front-panel 4 mm sockets through which start/stop and reset can be operated, as an alternative to its top-mounted push switches, so an experiment can be timed from switches or contacts rather than by hand.
What batteries does the Digital Stopclock use?
The Digital Stopclock is powered by two AA/R6 or HP7 cells, which give many months of use in normal school timing. Please ask us whether cells should be included when we prepare your quotation.
Can the Digital Stopclock be used with light gates?
For light-gate work, a separate Centisecond Timer Module provides extra facilities beyond the Digital Stopclock itself. Please contact us to check which light-gate timing option we can quote for your experiment before you place an order.
Who supplies the Digital Stopclock?
