Vaiseshika Precision Vernier Potentiometer

Min. Order (MOQ) 1 Piece(s)
Brand Name VAISESHIKA

we are offering vaiseshika precision vernier potentiometer. description "vaiseshika" precision vernier potentiometer type - 9407 is designed for the measurement of voltage & current of a high order of accuracy. it can be used as a laboratory standard; for routine or accurate measurement of potential, resistance or current; as a standard for calibrating potentiometer; for standardizing electrical currents for electrical measuring instruments; and with thermocouples etc. excellent performance is achieved by the use of switches throughout the measuring circuit. a main switch divides the over all potential down to 0.1 v steps and the two successive 100 way switches divide down to 0.001 v and o.oooo1 v; a range switch multiplies the range by 1, 0.1 and 0.01 when required to achieve better resolution of measurement. these 100 way switches were specially designed for the potentiometer so that thermal e.m.f's generated at the contacts are minimized with low contact resistance. more over the circuit is designed to eliminate current flow through the 100 way switch contacts at balance, thus removing any error which might arise through changes in contact resistance featuresaccurate measurement of potential, current and resistance.highest quality manganin wire well-aged standards.high stepwise resolution of 2microvolt at the last range switch setting.excellent accuracy of 0.005.impeccable craftsmanship in construction, rigorous testing and simplicity of operationhard silver plated, self-cleaning switches with minimum contact resistance errors specificationrange of measurement: 0 to 1.90100 volt. range range switch setting0 micro v to 1.90100v : x10 micro v to 0.190100v : x0.10 micro v to 0.0190100v : x0.01 for our complete product range.

Vaiseshika DC Potentiometer

Brand Name VAISESHIKA

DescriptionThe Precision DC Potentiometer Type - 9408 has been designed to provide the highest standards of accuracy over a period of many years without any maintenance, whilst at the same time allowing rapid and easy operation. The most outstanding contribution to the development of potential meters in recent years resulted from the introduction of the unique Vaiseshika Low Resistance Precision instrument switch, used through out the Precision DC Potentiometer.This switch was developed after several years of research into the fundamental factors affecting contact resistance. The stationary contacts are silver clad copper bars, mounted in a robust insulating frame. The brush, which is composed of several contact springs, each of which is independent of the others and is unrestricted in its movement, makes a bridge contact between adjacent bars in a symmetrical manner. As a result, low and consistent contact resistance is achieved without high contact pressure or mechanical wear. After a life test of some 20, 000 operations, the switch was still mechanically sound and its stability had actually improved in the narrow range specified. The over all switch resistance is approximately 0.001 Ohm and the variation of contact resistance is less than 0.0001 Ohm. For our complete product range please
