we are offering vaiseshika precision kelvin cum-wheatstons bridge. description
"vaiseshika" kelvin-cum-wheatstone bridges type : 9405 are important instruments in the measurement of resistance as low as 0.1 micro ohms to highest value of 1 ohm. manganin has the quality of very low temperature co-efficient which is a critical parameter for resistance standards manufacturing. kelvin cum wheatstone bridge 9405 is also constructed with manganin coils & sheet. phosphor bronze silver plated switches have been used to minimise the residual resistance error. four standard decade dials, ratio selector & plug keys facilitate accurate null detection.
user can easily change over from kelvin section to wheatsone bridge section & vice-a-versa with the help of a selector switch.
