Standard Resistance Box

Standard Resistance Box is a device used to provide precise electrical resistance for calibration and testing purposes. It consists of a set of resistors with known values, which can be dialed in to achieve the desired resistance. It is essential for accurate measurements in electrical engineering. Standard Resistance Box : Model SRB-1 Used as reference standard To be used with Kelvin Double bridge Model KDB-2031 2081. (Range 1 milli-ohm to 1K Ohms) 7 different values of 1 m,10m,100mohms, 1 , 10, 100 & 1Kohm. Accuracy 0.5 % Current ratings are for 1mohm(20A), 10mohm(10 A), 100 mohms (2A), 1ohm (50 mA), 10 ohm (10 mA), 100 ohm (5 mA), 1 Kohm (1mA)
