YOU NAME IT WE HAVE IT
 Acculab Educational Desk Meter Moving Coil: Meters are made from best quality material incorporating Jewel bearings, Hardened & Precisely Polished Pivots & chemically treated hair spring for corrosion protection. Meters are fitted with Alnico High Flux Density magnets & have Linear scale with sharp pointer & anti parallax mirror for error free reading. All
meters are housed in moulded dust proof case with zero adjuster accessible from front. All meters confirm to IS specifications.
M.O. 65 : Round Dial Accuracy ±2% of FSD, Scale Length 55 mm ± 2mm. Available in desk top stand with top terminals or front terminals. Stands are made of ABS Plastic & have lock type terminals.
Dual Range Meters available on request.
M.R. 100 : Rectangular Dial Accuracy ±2% of FSD, Scale Length 85mm, clear acrylic front cover & front terminals ABS plastic stand.
All common ranges 100 pA - 30A, 50mV - 250V, Galvo 30.0-30 or 50-0-50
are available. Moving coil meter can be supplied incorporating rectifier for
AC use.
 Rheostat:- Metal or bakelite feet to hold the porcelain pipe with the help of rod
& nut. Guide rod carries contact block. Slides are provided with Phosphorous Bronze contacts & move perfectly on sliding rod. 3 terminals are provided, 1 is connected to slide block enabling the Rheostat to act as Potentiometer. Oxidized Eureka wire is wound on an insulating heat resistant
porcelain pipe. Total resistance and maximum current capacity are marked on slider. Rheostats are available in tube dia of 4.4 cm & 5.6 cm.Since they are open type, unprotected rheostat, they should not be used in excess of 50 volts. For various range of ohms & Amps
refer to catalogue chart. Groove type Rheostat wound with Kanthal / Nichrome wire also available.
 Resistance Box Plug Type :- To introduce resistance in circuit. Consisting of thickbrass blocks 12 mm, tappered, interchangeable plugs, fitted on a thick hylum sheet.
Selected double cover Manganin wire is wound on bakelite spool. The windings are double silk covered & non-inductive. The wire is coated to minimize the effect of change of temperature. Sufficient time is given to bobbin to provide equilibrium. The coils are mounted on the lower side of hylum sheet. Various coils are connected by double contact system and infinity plug is provided. The whole assembly is fitted on a teak wood box which is polished. Accuracy ±0.05% to ±0.1 %. All ranges upto 10,000 D are available.
 Decade Resistance Box :- Designed for quick, accurate work with laminated special grip contact rotated by a knob. Resistor Values printed on the panel are indicated by a pointer. Each contact position is indicated by a click. Each dial has 10
coils of equal value (may be 1/10, 1, 10, 100 or 1000/2). Manganin coils are non- inductively wound, properly varnished and aged for permanence of values over a period of time. Accuracy ± 0.05 % to ±0.1 %. DRBs are available in 1 dial, 2 dial upto 5
- dials, in teak wood box or chanel in chanel
style metal box which is powder coated.
 Post Office Box :- Interchangeable, Taper Plug type with split brass contact blocks 12mm thick. Npn-inductively wound, fully impregnated mangnin resistance coils having negligible temperature coefficient. The ratio arm each has resistance of 1 Q , 10/3,100/2, and 1000/3 in 4 ratio P.O. Box& 10/3 ,100/3 and 1000/3 in 3 ratio P.O. Box. Series arm has a resistance 11 to 11110 x 1/3 given by 16 coils. The panel is clearly engraved with nominal resistance values. 2 spring keys for battery & galvanometer are provided. External connections via 4 mm sockets are also available. Fitted in polished Teak-wood box with lid.
