Our product range contains a wide range of Electronic Lab Trainer, Kelvin Bridge, Post Office Box Wheatstone Bridge, Wheatstone Bridge and Digital Electronic Circuit Trainer
Kelvin Bridge For precision measurement of low resistances, range 10-4 to 1 ohm. With a rotary dial having ten coils of 0.1 ohm each and a circular slide wire resistance reading in steps of 0.001 ohm. A multiplier of 0.1 enables readings upto 0.0001 ohm. Separate current & potential terminals are provided. Properly aged manganin coils are used. Accuracy 0.1% or 0.2% of the slide wire length whichever is greater.
Post Office Box Wheatstone Bridge With two ratio dials of 10, 100 and 1000 ohms each and a resistance arm of four dials, each of ten coils of 1, 10, 100 and 1000 ohms, giving total resistance of 11, 110 ohms, with 4 mm socket terminals for battery, galvanometer and unknown resistance. Highly stabel resistances are used. Accuracy 0.1%.
Wheatstone Bridge Four gap system, enabling two additional resistances to be interpolated in the additional gaps, enables greater accuracy of measurement by reducing unwanted resistances to a minimum.Two brass strips are provided to close the gaps when so required. Complete with jockey.
