Digital Frequency Meter Type Manufacturer,Supplier and Exporter in India
Product Code : EL-DMI-1036
Jlab Export is a leading Digital Frequency Meter Type Manufacturer,and suppliers in India
Digital Frequency Meter Type (code EL-DMI-1036) is a bench digital frequency meter that measures from 1 Hz to 50 MHz and shows the result on a 6-digit display. Its internal clock uses an oven-controlled crystal, and the input is protected up to 550 V (DC + peak AC), which suits electronics, communication and physics labs that test oscillators and signal generators. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Frequency Meters?
| Model | What it measures | Display | Reference and form |
|---|---|---|---|
| This meter (EL-DMI-1036) | 1 Hz to 50 MHz, general signals | 6-digit | Oven-controlled crystal clock; bench cabinet |
| Digital Mains Frequency Meter | Mains frequency | Three-digit | Crystal-controlled reference; panel-mounting cabinet |
| A.F. Oscillator Function Generator Cum Digital | Built-in frequency meter on separate terminals, alongside a sine and square-wave generator | Digital readout | Combined generator and meter |
Choose this meter when you need a stand-alone counter that reaches 50 MHz with an oven-controlled time base. The mains frequency meter is meant for fixed panel monitoring of the supply, and the oscillator-cum-frequency-meter suits benches that want a signal source and a frequency readout in one cabinet.
What Is the Digital Frequency Meter Used For?
A digital frequency meter counts the cycles of an input signal during a precisely timed interval set by its internal crystal clock, and displays the count as a frequency. Keeping the crystal in a temperature-controlled oven means the time base drifts very little as the room warms or cools. In the lab it is used to set and check function generators, measure the output of LC, RC and crystal oscillators, verify timer and multivibrator circuits, and follow carrier and intermediate frequencies in communication experiments. Typical users are B.Sc. electronics, engineering, polytechnic and ITI electronics labs and repair workshops.
Signals of about 20 mV r.m.s. are enough from 10 Hz to 1 MHz; above that, feed a slightly stronger signal. Never apply more than the stated input protection, and let the meter warm up so the crystal oven reaches its working temperature before precise readings.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Your mains supply voltage, as the listing does not state the power input.
- Any signal generator or oscillator trainers to be quoted with the meters.
Frequently Asked Questions
What frequency range does the meter cover?
From 1 Hz to 50 MHz, shown on a 6-digit display.
How sensitive is the input?
It needs 20 mV r.m.s. from 10 Hz to 1 MHz, and the requirement rises to 50 mV r.m.s. at higher frequencies up to 50 MHz.
Why does an oven-controlled crystal matter?
The meter’s readings are only as steady as its time base. Holding the crystal at a constant temperature keeps the clock frequency stable as the lab temperature changes, so repeat readings agree closely.
Is the input protected against high voltages?
Yes, up to 550 V (DC + peak AC). Stay below that limit when connecting circuits with a DC level or large signals.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, trading as JLab, is a manufacturer of electronic test and digital measuring instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This meter is built in JLab’s own works, not procured from a trader, so institutes, dealers and importers buy direct from the factory; each instrument is checked by eye before packing and repeat orders come from the same source. JLab is registered as a manufacturing enterprise under MSME Udyam number UDYAM-HR-01-0003849 and exports under Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Liberia in West Africa, Japan in East Asia, Malawi in East Africa, the Maldives in South Asia and the USA in North America.
