Digital R.P.M. Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-DMI-1031
Jlab Export is a leading Digital R.P.M. Meter Manufacturer,and suppliers in India
Digital R.P.M. Meter (code EL-DMI-1031) is a non-contact digital tachometer that reads rotational speed from 100 to 10,000 R.P.M. on an LCD display. It runs on a 9 V battery and comes complete with its sensor and a working manual, so students and technicians can measure the speed of motors, wheels and shafts in physics and engineering labs without touching the moving part. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with the JLab Stroboscope?
| Model | Range | Readout | Power | How it measures |
|---|---|---|---|---|
| This R.P.M. meter (EL-DMI-1031) | 100 to 10,000 R.P.M. | Digital LCD | 9 V battery | Non-contact, with sensor |
| Stroboscope | 100 to 10,000 R.P.M. | Calibrated dial | Mains operated; battery optional | Stroboscopic effect, without connecting to the shaft |
Both cover the same speed range. Choose the R.P.M. meter when you want a direct digital reading from a battery-powered instrument that is easy to carry between benches; choose the stroboscope when students should also see the stroboscopic effect, where a rotating part appears to stand still.
What Is the Digital R.P.M. Meter Used For?
Rotational speed is one of the most common measurements in mechanics and machine labs. With this meter, students check the speed of a motor shaft or flywheel, see how speed changes with supply voltage or load, compare pulley and gear ratios, and confirm the speed of fans, centrifuges and rotating demonstration apparatus. Because the reading is taken without contact, it adds no friction to the rotating part and keeps hands away from it. Typical users are physics and engineering colleges, polytechnics and ITI workshops, and school labs running motion and energy projects.
Read the working manual before first use to set up the sensor correctly, hold the sensor steady while the reading settles, and stay clear of moving machinery. Remove the battery if the meter will be stored for a long time.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Whether you also want a stroboscope, which covers the same range and shows the stroboscopic effect.
- Any spare batteries or extra copies of the working manual for your lab.
Frequently Asked Questions
What speed range does the meter cover?
From 100 to 10,000 R.P.M., shown on an LCD display. Speeds below or above that range are outside the listed specification.
Does it need to touch the rotating shaft?
No. It is a non-contact type, used with the sensor supplied, so the reading is taken without any connection to the shaft or wheel.
What powers the meter?
A 9 V battery. The listing does not mention a mains adaptor, which keeps the meter portable around the lab.
How is it different from a stroboscope?
JLab’s stroboscope covers the same speed range but reads on a calibrated dial, runs from the mains (battery optional) and lets students watch the stroboscopic effect. This meter gives a direct digital reading from a battery.
Who makes the Digital R.P.M. Meter?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its Ambala works in Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of digital measuring and physics lab instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The meter is built at JLab’s own works and not sourced from a trader, so colleges, workshops, dealers and importers buy factory-direct; each unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Eswatini in Southern Africa, Australia in Oceania, Argentina in South America, Malaysia in Southeast Asia and Ireland in Western Europe.
