Decade Resistance Box, Dial Type
Product Code : LSK-EAE-11112
Decade Resistance Box, Dial Type (SKU LSK-EAE-11112) sets a resistance with rotary dials, each dial switching one decade of high-stability 1% metal film resistors, with the decades connected in series. Built in two-, three- or four-dial versions and usable on AC or DC, it serves circuit, bridge and calibration practicals in schools, colleges and electronics labs. Science Lab Supplies manufactures it at its factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, supplying schools, colleges, tender contractors and distributors first-hand.
Specifications
Every specification of the decade box is shown in the table below. Briefly, the box uses high-stability 1% carbon metal film resistance elements arranged in series-connected decades on two, three or four dials, works on AC or DC, and can be built with constantan or manganin wound coils where higher accuracy is required.

Applications and Experiments for the Decade Resistance Box
Turning the dials adds the decade settings together, so any value within the range can be set quickly and read straight off the dials without pulling plugs. That convenience makes the box useful physics lab equipment in India for Class 12, B.Sc. and diploma electrical work.
- Class 12 physics: known resistance in meter bridge and potentiometer experiments, and in Ohm's law circuits with the Ohms Law Kit Apparatus.
- B.Sc. practicals: shunt and series resistance for converting a galvanometer into an ammeter or voltmeter.
- Balancing the known arm of a bridge, or checking a Portable Wheatstone Bridge Apparatus Circuit Board.
- Diploma and ITI electronics: setting trial resistances in AC and DC circuits.
Turn the dials only when the circuit current is low, and do not exceed the power the resistors can dissipate.
Standard Scope of Supply
The Decade Resistance Box, Dial Type is supplied as a single unit as described above, in the two-, three- or four-dial version you select. State whether metal film elements or constantan or manganin coils are wanted; decade values and optional accessories appear on the quotation.
Packing, MOQ and Lead Time
Ask for one decade box or a set for every electrical bench, naming the number of dials needed. The Science Lab Supplies quotation then gives packing, delivery time and price for that quantity, and bridges, meters or plug keys can be added.

Frequently Asked Questions
How many dials does the Decade Resistance Box, Dial Type have?
It is made in two-dial, three-dial and four-dial versions. Each dial switches one decade, and the decades are connected in series so the dial readings add up to the total resistance.
Can it be used on AC as well as DC?
Yes. The metal film resistance elements make the box equally suitable for AC or DC circuits, so it can be used in both direct-current and alternating-current practicals.
Is a higher-accuracy version available?
Yes. As well as the standard 1% carbon metal film elements, the box can be built with constantan or manganin wound coil resistance for higher accuracy. Mention this when you request a quotation.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer of this decade box, which is produced at its Saha, Ambala site in India. Quotations come directly from that manufacturing site, so there is no separate trading company involved.
