Jlab Export is a leading Stop Clock Manufacturer,and suppliers in India
Stop Clock (code EL-MI-2125) is a Smith-type analogue stop clock in a metal case with fly-back action, used to time pendulum swings, cooling curves and other experiments in school and college labs. A lever on the right side starts and stops it, a press on the other side sends the hands back to zero, and a subsidiary dial below the second hand records 0 to 60 minutes. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Choose this clock when you want a Smith-type analogue timer with a metal case and fly-back reset. The Stop Clock Mechanical has both hands sweeping on a large body, and the digital stop clock gives a numerical reading but needs mains power.
What Is the Stop Clock Used For?
A stop clock times an event from a start signal to a stop signal, and its large dial can be read by a whole group at the bench. In physics practicals it times a counted number of oscillations of a simple pendulum to find the time period, and it marks the regular intervals at which temperature is noted for a cooling curve; in chemistry it times the progress of a reaction, and in biology the rate of a process such as transpiration. Its 0 to 60 minute subsidiary dial keeps count of longer runs, so the same clock serves both short and long experiments in school, college and ITI labs.
Start the clock with the right-hand lever at the exact moment the event begins, stop it with the same lever, read the minutes from the subsidiary dial and the seconds from the main dial, then use the press on the other side to fly the hands back to zero for the next trial. Keep the clock away from heaters, water baths and magnets on the bench.
What to Specify When Ordering
- Analogue or digital — this Smith-type clock, the mechanical model with two sweep hands, or the quartz digital stop clock.
- Quantity — the minimum order is 10 clocks; one per practical group is the usual plan.
- Companion apparatus — pendulum bobs, stands and thermometers for the timed practicals can be quoted together.
Frequently Asked Questions
How is the stop clock started, stopped and reset?
A lever on the right side of the case starts and stops it. Once it has been stopped, a press on the other side returns the hands to zero — the fly-back action.
What is the longest time it records?
The subsidiary dial below the second hand records 0 to 60 minutes. The graduation of the second dial is not given in the listing, so ask JLab if you need the smallest reading.
What does “Smith type” mean here?
It describes the design pattern of the clock. JLab makes this clock itself, and the name implies no link with any other company.
How does it differ from the Digital Stop Clock?
This is an analogue clock with hands and a minute dial. The digital model is quartz controlled with a 3½-digit seven-segment display and runs on 230 V AC mains.
What should an export quotation request include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and any tender reference.
Who manufactures this 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, a manufacturer of school lab instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The stop clock is assembled at JLab’s own works and not bought from a trader, so schools, colleges, dealers and importers buy from the source, each clock is visually inspected before it ships, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Taiwan in East Asia, the Maldives in South Asia, Mozambique in East Africa, Sudan in North Africa and Costa Rica in Central America and the Caribbean. Tender buyers can use the JLab lab tenders page.
