Rheostats
Rheostats
Rheostats are mainly used for regulating electric current in industry and laboratory where these are used as adjustable resistors in electrical circuits. With three terminal provisions, these can be used to vary a D C potential smoothly from zero to maximum.
 
Decade Resistance Box
PL 33
Decade Resistance Box consists of decade switches with resistors. Each decade switch has 1-10 positions in addition to zero position. Specially designed switch with self cleaning and silver plated contacts ensure very low contact resistance and long life.
PL 34
Decade Resistance Box consists of decade switches with precision resistors. Each decade switch has 1-10 position in addition to zero position. The decades are housed in metallic rugged casing and provided with knobs having ribs for comfortable operation.
 
KELVIN BRIDGE PL 39
KELVIN BRIDGE PL 39
This instrument employs the double Kelvin Bridge principle for accurate measurement of low resistances. Twin, 5-position ratio arm, combined with a decade & slide wire, provide a wide range of resistance measurement, i.e. 0.2 micro-ohms to 11 ohms with high accuracy. Two or four terminal measurements may be employed. Current up to 10 A can be used during measurement.
 
LIGHT SPOT GALVANOMETER PL 64
LIGHT SPOT GALVANOMETER PL 64
The instrument consists of a taut suspension movement, light source, projection system, scale and sensitivity control switch. All components of the instrument are housed in a dust free aluminium cabinet nicely finished by stoving enamel paint.
 
WHEATSTONE BRIDGE
WHEATSTONE BRIDGE
TOSHNIWAL Portable Wheatstone Bridge PL32.03 is a very precise and portable instrument. This Wheatstone Bridge is designed to afford maximum convenience for a wide range of resistance measurement without the need of external accessories. The resistance coils in ratio & series arms are made from non-inductively wound and aged best quality manganin wires having negligible effect of ambient temperature variation, for long term stability. Switches used in this instrument are of self cleaning type having very low contact resistance & long life.
 
Potentiometer
PL 51
Toshniwal Students’ Potentiometer is a functional, general purpose instrument particularly suitable for laboratories, colleges etc. The range is 0-1.8 volts, which is directly readable in volts & milli volts. Standardization is done with the help of a built-in specially designed circuit, without altering the dial setting.
PL 52
The potentiometer consists of a slide wire and switch with precision coils. Both slide wire and coils are made from manganin wire and are aged for long term stability before mounting in instrument. The measuring range of the potentiometer can be selected by a range selector switch. Electronic Voltage Reference (EVR) having performance comparable to standard cell operates on built-in dry cells.
