Standard Low Resistance Box

Standard Resistance Box (SRB-17) 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 (SRB-17) Used as reference standar Range: 20 Micro-ohm to 100 Kohms Accuracy : 0.5 % for 20 & 50 Micro-ohm & 0.2 % for other values. Manganin wire is used for Resistance Coils 14 different values of 20 uW, 50 uW, 100 uW, 1 mW, 10mW, 50mW, 100mW,500mW, 1W, 10W, 100W, 1kW , 10KW & 100 Kohms Power Rating (VI) of all Resistors is more than 1 Watts Current ratings are for 20 uW ( 250 A), 50 uW (150 A), 100 uW (125 A), 1 mW (50 A),10mW (15 A), 50mW (6 A), 100mW (3.5 A), 500mW (2.5 A), 1W (1.25 A), 10W (0.6 A), 100W (0.12 A), 1kW (10 mA), 10KW (3mA) & 100 Kohms ( 1.2 mA) Accuracy claimed by us can be checked by any NABL Accredited lab. Charges by NABL Lab are extra . We also make - Standard Resistance Box MODEL SRB-19 Cover all values from 20 uW to 1W. Shunts of 1milli-ohm ,1000 A or 0.1 milli-ohm 1000 A are also made by us.
