Owen Bridge (code EL-SI-8076) is an AC bridge for measuring unknown inductance by Owen’s method, used in BSc physics and electrical measurement labs. Fitted in a teak wood case, it has a built-in 1 kHz sine-wave source, a null detector with digital display, decade capacitor dials C3 and C4, decade resistance dials R2 and R3, and an internally fixed 1000 ohm arm R1. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Capacitance-Standard Inductance Bridges?
| Model | Capacitor dials | Resistance arms | Unknowns |
|---|---|---|---|
| This Owen bridge (EL-SI-8076) | C3 and C4, x0.1 µF | R3 x10, x100, x1000 ohm; R2 x100 ohm; R1 fixed at 1000 ohm | Not stated |
| Self Inductance Anderson Bridge | C, x0.01 µF | R1 x1, x10, x100 ohm; M x10, x100, x1000 ohm; R2, R3, R4 fixed at 1 kilo-ohm | Four supplied |

All three are listed with a 1 kHz sine-wave source and a digital null detector. The Owen bridge is the one with two capacitor dials, in steps ten times larger than the single capacitor dial of the other two; choose it when your syllabus names Owen’s method, and choose a model with supplied unknowns if you want practice coils included.
What Is the Owen Bridge Used For?
Owen’s bridge measures inductance in terms of capacitance and resistance. Its balance conditions do not depend on the frequency of the source, and the inductive and resistive balances can be set with separate controls, so balancing is quick and the method covers a wide range of inductances. That makes it a regular choice in AC bridge practicals for BSc physics and for electrical measurement courses in engineering colleges and polytechnics, often taught alongside the Maxwell and Anderson bridges.
In use, connect the coil under test at the marked 4 mm sockets, switch on the built-in 1 kHz source and set its amplitude, then adjust the R2 and R3 dials and the capacitor dials until the digital null detector reads a minimum. Record the settings and work out the inductance and the coil’s resistance from the Owen balance equations, keeping leads short to limit stray pickup.
What to Specify When Ordering
- Quantity — the minimum order is 10 bridges, supplied individually.
- Unknown inductances — the listing does not mention supplied unknowns, so add inductance boxes or coils if you need test inductances.
- Mains supply — state your local mains voltage so JLab can confirm the built-in source suits it.
Frequently Asked Questions
What does the Owen Bridge measure?
Unknown inductance, by Owen’s method, using its built-in 1 kHz sine-wave source and digital null detector.
What dials does it have?
R3 has decade dials of x10, x100 and x1000 ohm, C3 and C4 are decade dials of x0.1 µF, R2 is a decade dial of x100 ohm, and R1 is fixed internally at 1000 ohm.
Are unknown inductances included?
The listing does not say so. Ask JLab when you enquire, or order an inductance box or coils as test pieces.
Why choose Owen’s bridge?
Its balance does not depend on frequency, and the two balance conditions can be met with separate adjustments, which makes it straightforward for students.
What should an export quotation request include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling requirements and any tender reference.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronic lab instruments manufacturer in India, incorporated in 2017 and working from Hargolal Road, Ambala, Haryana. The Owen bridge is made at JLab’s own works instead of being bought from a trader, so universities, colleges, dealers and importers deal with the maker; each instrument is visually inspected before it leaves, and repeat orders are handled by the manufacturer. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — Papua New Guinea in Oceania, Saudi Arabia in the Middle East, Gambia in West Africa, Sudan in North Africa and Belgium in Western Europe, for example. Tender details are on the JLab lab tenders page.
