The SRX and Series are cost effective, stable, laboratory or portable resistance standards. Their ruggedness and small size plus their low temperature coefficient makes the SRX Series ideal for any applications outside of laboratory environment within the temperature range of 18°C to 28°C. Because of the low temperature coefficient, they require no oil-or-temperature bath. The binding posts are constructed of low-thermal emf material.
The SRX series resistance standards are available in values ranging from 1 mΩ to 100 MΩ, with custom values available, to satisfy any requirement For higher resistances, the SRC series resistance standards are available in values ranging from 190 MΩ to 10 TΩ, with custom values available.
It is possible to maintain SRX/SRX resistance standards indefinitely. They are reliable due to their closed, rugged design and sealed resistors. The units are resistant to electromagnetic interference (EMI) because of their metal enclosure.
