Four Dial Condenser Box Manufacturer,Supplier and Exporter in India
Product Code : EL-SI-8089
Jlab Export is a leading Four Dial Condenser Box Manufacturer,and suppliers in India
Four Dial Condenser Box (code EL-SI-8089) is a decade capacitance box for physics and electrical labs, with four dials of 10 x 0.001, 10 x 0.01, 10 x 0.1 and 10 x 1 mfd, so a known capacitance can be set in steps as small as 0.001 mfd. The same box is also offered in two-dial and three-dial versions. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Four Dial Condenser Box Used For?
A decade condenser box does for capacitance what a resistance box does for resistance: the value it presents is the sum of the four dial settings, so students can dial in a known capacitance and change it in steps without rewiring. It serves as the adjustable standard arm when balancing De Sauty and Wien bridges, sets C in RC time-constant and filter experiments, and shows how a resonance or cut-off frequency moves as the capacitance changes in B.Sc. physics and engineering practicals. Change the dials with the supply switched off, keep the applied voltage within the rating JLab confirms for your order, and store the box in a dry place.
Frequently Asked Questions
What capacitance can be set on this box?
The four dials are 10 x 0.001, 10 x 0.01, 10 x 0.1 and 10 x 1 mfd, and the capacitance set is the sum of the four dial settings. The smallest step is 0.001 mfd.
Is a two-dial or three-dial version available?
Yes. The listing also names Two Dial and Three Dial Condenser Boxes; ask JLab for their dial ranges.
What type of capacitor and working voltage does it use?
The listing does not say. Tell JLab the highest voltage in your circuits and ask for the capacitor type, tolerance and working voltage of the box you are quoted.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab) makes the condenser box at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab instruments manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The condenser box is produced at JLab’s own works, not bought in from a trader, so colleges, dealers and importers buy direct from the maker. JLab exports worldwide and ships to buyers in every region — Greece in Southern Europe, Bulgaria in Eastern Europe, Latvia in Northern Europe, Eswatini in Southern Africa and Belgium in Western Europe, for example. Tender information is on the JLab lab tenders page.
