Digital Stop Clock Manufacturer,Supplier and Exporter in India
Product Code : EL-MI-2127
Jlab Export is a leading Digital Stop Clock Manufacturer,and suppliers in India
Digital Stop Clock (code EL-MI-2127) is a quartz-controlled bench stop clock with a 3½-digit, 12.5 mm bright seven-segment display, used to time experiments in school and college labs. JLab introduced it to overcome the difficulties of mechanical stop clocks: a mini toggle switch starts and stops it, and the push-button reset works only in stop mode. It runs on 230 V AC mains and is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with JLab’s Analogue Timers?
| Model | Display | Controls | Power or movement |
|---|---|---|---|
| This digital stop clock (EL-MI-2127) | 3½-digit seven-segment, 12.5 mm | Toggle switch start/stop; push-button reset in stop mode only | Quartz controlled; 230 V AC mains |
| Stop Clock | Hands; 0–60 minute subsidiary dial | Side lever start/stop; fly-back reset press | Smith-type analogue clock in a metal case |
| Stop Clock Mechanical | Two sweep hands, seconds and minutes | Start/stop lever on the left; zero reset lever on the right | Mechanical; large metal body |
| Stop Watch | Transparent face, reads 1/10th of a second | One top lever for start, stop and zero | Jewelled movement; hand-held |
Choose the digital clock for a bench where mains power is available and you want a numerical display and a reset that cannot be pressed by mistake while timing. The analogue clocks need no mains supply, and the stop watch can be carried outside the lab.
What Is the Digital Stop Clock Used For?
It times physics, chemistry and biology practicals at the bench: the time period of a simple pendulum, temperature intervals on a cooling curve, the time a reaction takes to reach a colour change, or the duration of a demonstration. The bright seven-segment digits can be read by a group around the bench, and the quartz control holds the stated ±0.1% accuracy. Because reset works only in stop mode, a student cannot clear a run by accident before the reading is written down.
Connect the clock to a 230 V AC supply, flick the toggle switch to start at the instant the event begins and back to stop, note the reading, then press the reset button to clear the display. Keep the clock away from water baths and spills, and switch it off at the mains after the practical.
What to Specify When Ordering
- Reading — confirm the resolution or least count your practical needs, as the listing gives both 0.1 s and 1 second.
- Supply voltage — the clock works on 230 V AC ±10%; mention your mains supply and plug type for export orders.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
What is the range and resolution of this digital stop clock?
The listing gives a range of 999.90 s, a resolution of 0.1 s and, in another row, a least count of 1 second. Please confirm which reading you need when you ask for a quote, and JLab will state it on the quotation.
How accurate is it?
The accuracy is listed as ±0.1%, as the timing is quartz controlled.
Can the reading be cleared by mistake while timing?
No. Reset is by a push button that works only in stop mode, so the clock cannot be reset while it is running.
What power supply does it need?
230 V AC mains, ±10%. For battery-free timing away from mains, see the analogue stop clocks and the stop watch linked on this page.
What details does an export quotation need?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, your mains supply and plug type, any packing or labelling needs, and a tender reference if applicable.
Who manufactures the Digital Stop Clock?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of school and college lab instruments, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The digital stop clock is built at JLab’s own works instead of being sourced from a trader, so schools, colleges, dealers and importers buy direct, each unit is visually inspected before dispatch, and repeat orders go back to the maker. JLab exports worldwide and ships to buyers in every region — for example Indonesia in Southeast Asia, Panama in Central America and the Caribbean, Guyana in South America, Eswatini in Southern Africa and North Macedonia in Southern Europe. Tender buyers can see the lab tenders page.
Other Timers and Timed Practicals
- Stop Clock — a Smith-type analogue bench clock with fly-back reset.
- Stop Watch — a jewelled-movement hand-held watch reading 1/10th of a second.
- Stop Clock Mechanical — a large analogue clock with two sweep hands.
- Simple Pendulum — the time-period experiment most often timed with a stop clock.
