Choose this model when a group needs to read the time at a glance, when you want split times or a running clock and calendar, or when timings may run past an hour. The mechanical watches need no battery and suit buyers who prefer a dial, and the economy digital model is the simpler choice for basic class sets.
What Is the Large Display Stopwatch Used For?
In the physics lab it times the oscillations of a simple pendulum in the class 11 practical, the fall of an object or the roll of a ball down an incline; in chemistry it times how long a reaction mixture takes to turn cloudy or change colour in rate-of-reaction work; and in biology it times pulse counts and reaction-time activities. The large digits help when one student calls out the time to a group, and the split function lets you note an intermediate time — for example after each lap or swing count — while the main timing carries on. Outdoors it serves for field studies and sports-day timing, worn on its neck cord or clipped to a stand.
Remember that hand timing is limited by the user’s reaction time, typically a few tenths of a second, so the hundredths digits become meaningful when you time many oscillations together and divide. Keep the stopwatch in its leatherette case when not in use, and replace the AA battery when the display fades.
What to Specify When Ordering
- Quantity — the minimum order is 10 stopwatches; one per practical group is a common lab plan.
- Spare batteries — one AA battery is included with each stopwatch; ask for spares if you want them.
- Delivery details — destination, delivery terms and any packing or labelling requirements.
Frequently Asked Questions
What resolution does this stopwatch have?
1/100 second for the first 30 minutes of timing, then 1 second resolution up to its 24-hour limit.
What is the split interval function?
It shows an intermediate time while the stopwatch keeps running, so you can record the time at a checkpoint without stopping the main count.
What comes with the stopwatch?
A neck cord, a leatherette case, a stand clip and an AA battery are supplied with it, according to the listing.
Is it digital or mechanical?
Digital: it has a quartz crystal movement, clickstop controls and a large LCD display, in a rugged ABS plastic case.
How does it differ from JLab’s mechanical stop watches?
The mechanical models read to 1/5th or 1/10th of a second on a dial and need no battery. This digital model reads to 1/100 second for the first half hour and adds split, clock and calendar functions.
What should I send for an export quotation?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling needs, spare batteries required, and a tender reference if relevant.
