Milliammeters (Dual Range) Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4648
Jlab Export is a leading Milliammeters (Dual Range) Manufacturer,and suppliers in India
Milliammeters (Dual Range) (code EL-SLE-4648) are dual-range meters for measuring small electric currents in milliamperes, with ranges listed from 0–1 mA through 0–20, 0–50 and 0–100 mA up to 0–500 mA. Each meter sits on a black and white ABS plastic desk stand, and they are used for diode, LED and other low-current practicals in school and college physics. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Current Meters?
| Model | Current scale | Ranges listed |
|---|---|---|
| This milliammeter (EL-SLE-4648) | Milliamperes | 0–1 mA up to 0–500 mA, dual range |
| Ammeter | Amperes | 0–1, 0–2.5 or 0–5 A; dual 0–1/3 or 0–2.5/5 A |
| Digital Ammeter | Amperes, digital display | 0–1.999 A and 0–19.99 A |
| Galvanometer | Very small currents | Used as a sensitive current detector |
Use the milliammeter whenever the current stays below half an ampere — the ampere-range meters would barely move. For currents of an ampere or more choose the ammeter or the digital ammeter, and for finding a balance point in bridge and potentiometer circuits use the galvanometer.
What Is a Milliammeter Used For?
A milliampere is one thousandth of an ampere, the size of current that flows in many electronic and low-power circuits. In the class 12 practical on the characteristic curve of a p-n junction diode, the milliammeter reads the forward current as the voltage across the diode is raised step by step; it is used in the same way for Zener diodes and LEDs, for the plate current of a diode valve, and in circuits with high resistances where an ampere-range meter would read almost zero. Having two ranges on one meter lets students start on the higher range and move to the lower one for a finer reading.
Connect the milliammeter in series with the component and never directly across a cell or power supply — even a small battery can drive enough current to damage it. Include a series resistor or rheostat when testing diodes and LEDs, so the current cannot rise beyond the range in use.
What to Specify When Ordering
- Range pair — choose two of 0–1, 0–20, 0–50, 0–100 and 0–500 mA, and the quantity of each combination.
- Circuit type — state whether the meters are for D.C. or A.C. use.
- Quantity — the minimum order is 10 meters.
- Matching meters — voltmeters, rheostats and plug keys for the same practical.
Frequently Asked Questions
Which ranges can I order?
The listing gives 0–1 mA, 0–20 mA, 0–50 mA, 0–100 mA and 0–500 mA, supplied as dual-range meters. Tell JLab which two ranges you want on each meter.
What is the difference between a milliammeter and an ammeter?
Only the size of current each is built to read. A milliammeter reads thousandths of an ampere, so it shows small currents clearly; an ammeter reads whole amperes.
Is it for A.C. or D.C. current?
This is not stated in the listing. Specify the type of circuit in your enquiry and JLab will confirm the meter.
What is the stand made of?
ABS plastic in black and white, described in the listing as unbreakable.
Who manufactures these milliammeters?
Jain Laboratory Instruments Pvt Ltd (JLab) makes them at its works in Ambala, Haryana, India, and supplies them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and electrical teaching-instrument manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The milliammeters are made at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy them factory-direct, each meter is looked over before dispatch, and repeat orders are handled by the maker. The company holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Myanmar in Southeast Asia, Uzbekistan in Central Asia, Finland in Northern Europe, Zambia in East Africa and Tunisia in North Africa.
For Low-Current Practicals
- Voltmeters Dual Range — to read the voltage across the diode or component.
- Diode Mounted — a diode valve on a transparent base for demonstrating how a diode conducts.
- Rheostats (Nichrome Type) — for limiting and adjusting the current.
- Plug Key — for switching the circuit on only while reading.
More apparatus is in the School Lab Equipment range.
