The new IET labs esi SR102 and esi SR104 are a highly stable (±0.5 ppm/year) and accurate (1 ppm), 100W and 10kW resistance standards.
The SR102 and SR104 standards available from Power Parameters are equipped for five-terminal measurements used for standard resistor readings and for temperature sensor readings.
Individual calibration data, which identifies the standard deviation and the temperature characteristics, is supplied with each unit.
In addition, each unit is equipped with a thermal well so that the exact temperature of the resistance.
The TEGAM precision transportable resistance standards are oil filled, hermetically sealed, five-terminal resistance standards designed for precision bench top or oil bath applications.
