Dielectric Constant Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SCD-1093
Jlab Export is a leading Dielectric Constant Apparatus Manufacturer,and suppliers in India
Dielectric Constant Apparatus (code EL-SCD-1093) is a bench instrument for calculating the dielectric constant of liquids and solids by a tuning method. A tunable high-frequency oscillator with an outer gang condenser is set for optimum tuning, shown on a meter; a dielectric is then placed between parallel plates, the change is detected again, and the difference is noted for the calculation. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Dielectric Constant Apparatus Used For?
The dielectric constant, or relative permittivity, of a material is the ratio of the capacitance of a pair of plates with the material between them to the capacitance of the same plates with air. In this apparatus the parallel plates form part of the tuned circuit of the high-frequency oscillator. Students first tune the gang condenser until the meter shows optimum tuning with no sample, then place the solid or liquid dielectric between the plates; its extra capacitance shifts the tuning, so the gang condenser is reset for optimum tuning again. The difference between the two settings measures the capacitance the dielectric added, and from it the dielectric constant is calculated.
Dielectric constants decide how capacitors are built and how insulating materials behave, which makes this a regular practical in B.Sc. physics and electronics labs. Keep the plates clean and dry between samples, place solid samples flat and centred, and make each tuning adjustment slowly near the meter peak.
What to Specify When Ordering
- Sample size and liquid holder — ask for the plate size and spacing, and how liquid samples are held, so you can prepare suitable specimens.
- Oscillator frequency — not stated in the listing; request it if your calculation needs it.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
Which materials can be tested?
Both liquids and solids, according to the listing. Ask JLab about the sample size and the way liquids are held between the plates.
How does the measurement work?
The oscillator is tuned with the gang condenser to the meter’s optimum point, the dielectric is placed between the parallel plates, the tuning is found again, and the difference is used to calculate the dielectric constant.
How is it different from the Dielectric Constant Kit?
The kit is listed for solid samples using an audio oscillator and a digital voltmeter. This apparatus uses a high-frequency oscillator with gang-condenser tuning and is listed for liquids as well as solids.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics lab instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The dielectric constant apparatus is made at JLab’s own works, not traded in, so colleges, universities, dealers and importers buy direct from the maker; 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 Honduras in Central America and the Caribbean, Tonga in Oceania, the UAE in the Middle East, Belgium in Western Europe and Mexico in North America. See the JLab lab tenders page for tenders.
