Q Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-TAMI-1018
Jlab Export is a leading Q Meter Manufacturer,and suppliers in India
Q Meter (code EL-TAMI-1018) is a mains-operated instrument that measures the Q, or quality factor, of an inductor at a measuring frequency of 1 kHz or 10 kHz, over a range of 0.1 to 100. The reading is shown on a moving-coil meter, and the instrument works on 220 V, 50 Hz. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Q Meter Used For?
The Q of a coil compares the energy it stores in its magnetic field with the energy it loses in each cycle; for an inductor it equals the inductive reactance divided by the coil’s loss resistance (ωL/R). A high-Q coil wastes little energy, while a low Q points to winding resistance, core losses or a poorly chosen wire gauge. The listing notes that Q is needed when designing coils or transformers, so this test and measuring instrument suits electronics and electrical engineering labs, B.Sc. and M.Sc. physics practicals, polytechnics and ITI electronics workshops where students wind or compare inductors.
Because inductive reactance rises in proportion to frequency, the same coil usually gives a different Q at 10 kHz than at 1 kHz, and comparing the readings shows students how losses change with frequency. The instrument has a balancing dial and a moving-coil meter; ask JLab for the operating procedure when you order, and keep the coil leads short, since long leads add resistance to the measurement.
What to Specify When Ordering
- Measuring frequency — the listing gives 1 kHz or 10 kHz; state whether you need both frequencies on one instrument.
- Mains supply — the instrument works on 220 V, 50 Hz; mention your local supply in the enquiry.
- Coils to test — add a decade inductance box or a set of inductance coils if students need known inductors.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
What does a Q meter measure?
It measures the quality factor of an inductor — the ratio of its reactance to its loss resistance. This model reads Q from 0.1 to 100 on a moving-coil meter.
At what frequency does it measure Q?
The listing gives a measuring frequency of 1 kHz or 10 kHz. Q depends on frequency, so record which one was used with each reading.
How is it different from the Digital L.C.R. Meter?
The Digital L.C.R. Meter reads inductance, capacitance and resistance on a digital display, with dissipation and quality factor read directly. The Q meter is a dedicated instrument for the Q of inductors, with an analogue moving-coil meter.
Who manufactures this Q meter?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of electronic lab instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Q meter is assembled at the company’s own works rather than sourced from a trader, so colleges, training institutes, dealers and importers deal directly with the manufacturer; every unit is visually inspected before it is packed, and repeat orders are handled by the same team. JLab exports worldwide and ships to buyers in every region — for example Norway in Northern Europe, Tajikistan in Central Asia, the Dominican Republic in Central America and the Caribbean, the USA in North America and Iraq in the Middle East. Institutions buying through tenders can see the JLab lab tenders page.
